  • How to count the number of listitems in an asp.bulletedlist with JavaScript

    - by Andy5
    Hi I have an asp:bulletedlist control, which sits inside a div tag, and I need to count the number of list items inside the control. Searching the internet, and noting the fact the html given back by the items is a list i.e. <li>, I thought I could use an example of: var listcontrol = document.getElementById('BulletedList1'); var countItems = listcontrol.getElementByTagName('li').length; However, when I do this, it throws and error saying that no object exists for this control. So, my problem is, and because I must do this clientside because I want to use this to set the height of the div tag, is how do you count the number of items inside a asp:bulletedlist control with javascript?

  • Designers, Expression or SharePoint Designer, and real source control

    - by David Lively
    I'm trying desperately to move from VSS to a real source control system. Options include TFS and SVN. My designers need to keep their ability to modify source files and instantly preview their changes in a browser without having to commit their changes. Using FPSE with VSS, this works flawlessly, since saving a file causes the copy in the working folder on the dev server to be updated, so they can just save and refresh their browser which is pointed at the dev server. The site in question consists of 350k+ lines of classic ASP code and some new ASP.NET MVC. They only need to be able to modify views within the MVC code, not C#. Though Expression includes a version of Cassini for local debugging, Cassini does not support classic ASP. Surely someone has solved this problem before. It can't be necessary to install IIS on each designer's machine (this is absolutely untenable). I need a way to have a common working folder on a dev webserver updated whenever someone saves a file locally, just like using FPSE. I'd rather not write an FPSE proxy that knows how to talk to TFS/SVN. Any suggestions? (I know I've asked this question in the past, but I haven't yet found a solution.)

  • Writing JavaScript from a Custom Control

    - by coffeeaddict
    I'm new to writing custom controls. I have MyCustomControl.cs and in my Render method I want to render out about 50 lines of JavaScript. What's the best way to do this, use the writer? protected override void Render(HtmlTextWriter writer) { writer.write(@"<script type....rest of opening tag here"); writer.Write(@" function decode(s) { return s.replace(/&amp;/g, ""&"") .replace(/&quot;/g, '""') .replace(/&#039;/g, ""'"") .replace(/&lt;/g, ""<"") .replace(/&gt;/g, "">""); };" ); I plan on having around 6 more writer.Write to write out some more sections here. Is that the best approach to actually perform the writing of JavaScript in this manor? or should I use ClientScript.RegisterClientScriptBlock? So what's the best practice or common way people are writing javascript from a custom control? (I'm not talking about a user control here!!, custom control/Class!) I also want to keep any indentation for readability once it's spit out/rendered on the client when viewing source.

  • ASP.NET Radio Button State and Back Key

    - by Dave S
    When using the browser back key on a page with radio buttons and using auto-postback, the state of the buttons (checked) stays the same while other parts of the page do not. This results in a situation where button two is checked and the cached page (because of server-side logic) displays a message that button 1 is checked. What is the best way to handle this situation? The following code example exhibits this behavior: [Form:] <asp:RadioButton ID="rb1" runat="server" AutoPostBack="true" Text="Button1" OnCheckedChanged="rb_CheckedChanged" GroupName="rbgroup" Checked="true" /> <br /> <asp:RadioButton ID="rb2" runat="server" AutoPostBack="true" Text="Button2" OnCheckedChanged="rb_CheckedChanged" GroupName="rbgroup" /> <br /> <hr /> <asp:Label ID="lbl1" runat="server">Button 1</asp:Label> [Code Behind:] protected void rb_CheckedChanged(object sender, EventArgs e) { if (rb1.Checked == true) lbl1.Text = "Button 1"; else lbl1.Text = "Button 2"; }

  • [Need help]: Issue with submit button and html file input control’s Click() method

    - by somesh
    Scenario: On click of a button, we dynamically create html file input (file upload) control on the page and call that file input controls Click() method. User then selects the file from the disk. There is a “Submit” button to upload the selected file. Problem: The problem is, when clicked on “Submit” button first time, the input value from the file input control is cleared. And the request does not go to the server. When clicked second time, the request goes to server with empty file input value. Why the first click on submit button does not send the request to server. And why it clears the file input control value? Note: The issue is observed only when we call Click() method programmatically. If we let user to click browse, then in that case, the "Submit" does not clear the input value and sends request to server on first click itself. Any help would be appreciated. Thanks in advance. By the way, server side code is in asp.net and client side in java script, testing on IE. -Somesh

  • “User Control” uses an incorrect event

    - by Lijo
    Hi, I am using two instances of a user control. But when I click on a button in the user control, both of the instances calls the function corresponding to the first event (AcknowledgeReceipt()) However, when I remove the first user control and clicks on the btnRequestClarification, it calls the correct method (RequestClarification()) Is there a way to correct this behavior? acknowledgeModificationPopupCtrl = (ConfirmationPopup)this.LoadControl("~/ConfirmationPopup.ascx"); plHConfirmationPopup.Controls.Add(acknowledgeModificationPopupCtrl); acknowledgeModificationPopupCtrl.ContinueClick += new EventHandler(AcknowledgeReceipt); RequiredFieldValidator reqFValidatorAcknowledge = (RequiredFieldValidator)acknowledgeModificationPopupCtrl.FindControl("reqValidatorTxt"); reqFValidatorAcknowledge.ValidationGroup = "AcknowledgeReceipt"; acknowledgeModificationPopupCtrl.ValidationGroup = "AcknowledgeReceipt"; btnAcknowledgeReceipt.Attributes.Add("onclick", "validateconfirmPopup('true','xx' ,’yyy','Note' ,'true'); return false;"); requestModificationPopupCtrl = (ConfirmationPopup)this.LoadControl("~/ConfirmationPopup.ascx"); plHConfirmationPopup.Controls.Add(requestModificationPopupCtrl); requestModificationPopupCtrl.ContinueClick += new EventHandler(RequestClarification); RequiredFieldValidator reqFValidator = (RequiredFieldValidator)requestModificationPopupCtrl.FindControl("reqValidatorTxt"); reqFValidator.ValidationGroup = "request"; requestModificationPopupCtrl.ValidationGroup = "request"; btnRequestClarification.Attributes.Add("onclick", "validateconfirmPopup('true',’kkk' ,’lll','ff' ,'true'); return false;"); Thanks Lijo

  • jquery.clone() and ASP.NET Forms

    - by Jeff
    So I have a page where I would like to be able to add multiple, dynamic users to a record in a database. Here's the rough start page: <div id="records"> <div id="userRecord"> Name: <asp:TextBox runat="server" ID="objNameTextBox"></asp:TextBox> <br /> Phone Number: <asp:TextBox runat="server" ID="objPhoneNumberTextBox"></asp:TextBox> <br /> </div> </div> And the jquery: $(function () { $(".button").button().click(function (event) { addnew(); event.preventDefault(); }); }) function addnew() { $('#userRecord').clone().appendTo('#records'); } So my question is what do I use within ASP.NET to be able to poll all of the data in the form and add a unique record for each #userRecord div within the #records div? Yes - I should change the userRecord to a class - I will deal with that. This is just simple testing here. Should I look in JSON for this type of function? I'm not familiar with it but could figure it out if that is indeed my best option. Thanks for the guidance!

  • The Microsoft Ajax Library and Visual Studio Beta 2

    - by Stephen Walther
    Visual Studio 2010 Beta 2 was released this week and one of the first things that I hope you notice is that it no longer contains the latest version of ASP.NET AJAX. What happened? Where did AJAX go? Just like Sting and The Police, just like Phil Collins and Genesis, just like Greg Page and the Wiggles, AJAX has gone out of band! We are starting a solo career. A Name Change First things first. In previous releases, our Ajax framework was named ASP.NET AJAX. We now have changed the name of the framework to the Microsoft Ajax Library. There are two reasons behind this name change. First, the members of the Ajax team got tired of explaining to everyone that our Ajax framework is not tied to the server-side ASP.NET framework. You can use the Microsoft Ajax Library with ASP.NET Web Forms, ASP.NET MVC, PHP, Ruby on RAILS, and even pure HTML applications. Our framework can be used as a client-only framework and having the word ASP.NET in our name was confusing people. Second, it was time to start spelling the word Ajax like everyone else. Notice that the name is the Microsoft Ajax Library and not the Microsoft AJAX library. Originally, Microsoft used upper case AJAX because AJAX originally was an acronym for Asynchronous JavaScript and XML. And, according to Strunk and Wagnell, acronyms should be all uppercase. However, Ajax is one of those words that have migrated from acronym status to “just a word” status. So whenever you hear one of your co-workers talk about ASP.NET AJAX, gently correct your co-worker and say “It is now called the Microsoft Ajax Library.” Why OOB? But why move out-of-band (OOB)? The short answer is that we have had approximately 6 preview releases of the Microsoft Ajax Library over the last year. That’s a lot. We pride ourselves on being agile. Client-side technology evolves quickly. We want to be able to get a preview version of the Microsoft Ajax Library out to our customers, get feedback, and make changes to the library quickly. Shipping the Microsoft Ajax Library out-of-band keeps us agile and enables us to continue to ship new versions of the library even after ASP.NET 4 ships. Showing Love for JavaScript Developers One area in which we have received a lot of feedback is around making the Microsoft Ajax Library easier to use for developers who are comfortable with JavaScript. We also wanted to make it easy for jQuery developers to take advantage of the innovative features of the Microsoft Ajax Library. To achieve these goals, we’ve added the following features to the Microsoft Ajax Library (these features are included in the latest preview release that you can download right now): A simplified imperative syntax – We wanted to make it brain-dead simple to create client-side Ajax controls when writing JavaScript. A client script loader – We wanted the Microsoft Ajax Library to load all of the scripts required by a component or control automatically. jQuery integration – We love the jQuery selector syntax. We wanted to make it easy for jQuery developers to use the Microsoft Ajax Library without changing their programming style. If you are interested in learning about these new features of the Microsoft Ajax Library, I recommend that you read the following blog post by Scott Guthrie: http://weblogs.asp.net/scottgu/archive/2009/10/15/announcing-microsoft-ajax-library-preview-6-and-the-microsoft-ajax-minifier.aspx Downloading the Latest Version of the Microsoft Ajax Library Currently, the best place to download the latest version of the Microsoft Ajax Library is directly from the ASP.NET CodePlex project: http://aspnet.codeplex.com/ As I write this, the current version is Preview 6. The next version is coming out at the PDC. Summary I’m really excited about the future of the Microsoft Ajax Library. Moving outside of the ASP.NET framework provides us the flexibility to remain agile and continue to innovate aggressively. The latest preview release of the Microsoft Ajax Library includes several major new features including a client script loader, jQuery integration, and a simplified client control creation syntax.

  • WPF Toolkit Charting and IndependentValueBinding, IndependentValuePath

    - by Joel Barsotti
    So I'm having a problem with the charting engine from the WPF toolkit. We haven't moved our data to a proper object model, so the ItemSource is backed with a DataView. First attempt <chartingToolkit:ScatterSeries x:Name="TargetSeries" DataPointStyle="{StaticResource TargetStyle}" ItemsSource="{Binding Path=TargetSeriesData}" IndependentValueBinding="{Binding Path=TargetSeries_X}" DependentValueBinding="{Binding Path=TargetSeries_X}" /> This crashes because, I believe, it thinks the bindings are the values to plot or some sort of mismatch. Second attempt <chartingToolkit:ScatterSeries x:Name="TargetSeries" DataPointStyle="{StaticResource TargetStyle}" ItemsSource="{Binding Path=TargetSeriesData}" IndependentValuePath="{Binding Path=TargetSeries_X}" DependentValuePath="{Binding Path=TargetSeries_X}" /> This crashes during the init step becaue the Path properties aren't backed with dependency properties and therefore cannot be bound. Third attempt <chartingToolkit:ScatterSeries x:Name="TargetSeries" DataPointStyle="{StaticResource TargetStyle}" ItemsSource="{Binding Path=TargetSeriesData}" IndependentValuePath="targetFooXColumnName" DependentValuePath="targetFooYColumnName" /> Now this works! But I wanted to use the binding so I can switch from using the targetFooXColumnName to the targetFooBarXColumnName. So this solution will cause a whole lot of hacky looking code to switch the Path's manually. Anyway to fix this? Can I use some sort of convertor to get the Binding properties to correctly pull the data from the columns in the DataView? Thanks, Joel

  • Good Laptop .NET Developer VM Setup

    - by Steve Brouillard
    I was torn between putting this question on this site or SuperUsers. I've tried to do a good bit of searching on this, and while I find plenty of info on why to go with a VM or not, there isn't much practical advise on HOW to best set things up. Here's what I currently HAVE: HP EliteBook 1540, quad-core, 8GB memory, 500GB 7200 RPM HD, eSATA port. Descent machine. Should work just fine. Windows 7 64-bit Host OS. This also acts as my day-to-day basic stuff (email, Word Docs, etc...) OS. VMWare Desktop Windows 7 64-bit Guest OS with all my .NET dev tools, frameworks, etc loaded on it. It's configured to use 2 cores and up to 6GB of memory. I figure that the dev env will need more than email, word, etc... So, this seemed like a good option to me, but I find with the VM running, things tend to slow down all around on both the host and guest OS. Memory and CPU utilization don't seem to be an issue, but I/O does. I tried running the VM on an external eSATA drive, figuring that the extra channel might pick up the slack. Things only got worse (could be my eSATA enclosure). So, for all of that I have basically two questions in one. Has anyone used this sort of setup and are there any gotchas either around the VMWare configuration or anything else I may have missed here that you can point me to? Is there another option that might work better? For example, I've considered trying a lighter weight Host OS and run both of my environments as VMs? I tried this with Server 2008 Hyper-V, but I lose too much laptop functionality going this route, so I never completed setup. I'm not averse to Linux as a host OS, though I'm no Linux expert. If I'm missing any critical info, feel free to ask. Thanks in advance for your help. Steve

  • cygwin GNU make .net program piping inconsistent behavior

    - by Codism
    This question may sound like a superuser question but I feel there is something related to programming. Anyway, my computer had a fresh installation of Win 7 64 and cygwin recently. Now I observed some problem with pipe handling in gnu make file. The following is the Makefile I use to reproduce the issue: all: fsutil | cat my-dotnet-console.exe | cat The problem is: for the first command line, the piping works every time but for the second command line, the piping barely works - I got no result for the second command for most cases, regardless of the environment (cmd or bash) in which the make file is invoked. However, if I copy paste the second command line into cmd (or bash), the pipe works every time. The following is my .net program: static void Main(string[] args) { Console.WriteLine(new string('a', 40)); Console.Out.Flush(); } The make version is 3.82.90 but the same problem was observed in a previous version (because of the windows path handling problem in 3.82.9, I replaced make.exe with a previous version). I don't know the exact cygwin version I have installed but the current version on cygwin.com is 1.7.11-1. Currently, my work around is to redirect the output to a temporary file but it would be great if I can avoid the temporary file. Thanks

  • Library Organization in .NET

    - by Greg Ros
    I've written a .NET bitwise operations library as part of my projects (stuff ranging from get MSB set to some more complicated bitwise transformations) and I mean to release it as free software. I'm a bit confused about a design aspect of the library, though. Many of the methods/transformations in the library come with different endianness. A simple example is a getBitAt method that regards index 0 as the least significant bit, or the most significant bit, depending on the version used. In practice, I've found that using separate functions for different endianness results in much more comprehensible and reusable code than assuming all operations are little-endian or something. I'm really stumped regarding how best to package the library. Should I have methods that have LE and BE versions take an enum parameter in their signature, e.g. Endianness.Little, Endianness.Big? Should I have different static classes with identically named methods? such as MSB.GetBit and LSB.GetBit On a much wider note, is there a standard I could use in cases like this? Some guide? Is my design issue trivial? I have a perfectionist bent, and I sometimes get stuck on tricky design issues like this... Note: I've sort of realized I'm using endianness somewhat colloquially to refer to the order/place value of digital component parts (be they bits, bytes, or words) in a larger whole, in any setting. I'm not talking about machine-level endianness or serial transmission endianness. Just about place-value semantics in general. So there isn't a context of targeting different machines/transmission techniques or something.

  • .NET Dependency Management Systems

    - by StriplingWarrior
    I have some .NET projects that are starting to get large enough to merit looking into Dependency Management solutions, so we don't have to copy binaries from one project to another. Here's what I've found so far: NPanday is based on a port of Maven. I can't tell how recently it was worked on, but the last release was in May 2011. NuGet seems to be under active development, and it appears to have support directly from Microsoft. Some people complained that it "only addresses dependency resolution," but I don't know what else it should address, or whether it has added more features since that point. It does appear to have recently added the ability to import binaries as part of the build process so we don't have to commit them to our repositories. Refix appears to still be in Beta, after having received no attention since Sept 2011. Would somebody with recent experience using any of these dependency management tools (or any others that work well) share your experience? Is NuGet mature enough to use it for dependency management? If not, what does it lack?

  • Converting listview to a composite control

    - by Paul
    The link below shows a listview composite control in its most basic form however I can't seem to extend this to what I'm trying to do. http://stackoverflow.com/questions/92689/how-to-define-listview-templates-in-code My listview has 1 tablerow with 2 fields. The first field contains 1 element whilst the second field contains 2 elements as shown below. <asp:ListView ID="lstArticle" runat="server"> <LayoutTemplate> <table id="itemPlaceholder" runat="server"> </table> </LayoutTemplate> <ItemTemplate> <div class="ctrlArticleList_rptStandardItem"> <table width="100%"> <tr> <td valign="top" class="ctrlArticleList_firstColumnWidth"> <a href="<%# GetURL(Container.DataItem) %>"> <%# GetImage(Container.DataItem)%> </a> </td> <td valign="top"> <span class="ctrlArticleList_title"> <a href="<%# GetURL(Container.DataItem) %>"> <%# DataBinder.Eval(Container.DataItem, "Title") %> </a> </span> <span class="ctrlArticleList_date"> <%# convertToShortDate(DataBinder.Eval(Container.DataItem, "ActiveDate"))%> </span> <div class="ctrlArticleList_standFirst"> <%# DataBinder.Eval(Container.DataItem, "StandFirst")%> </div> </td> </tr> </table> </div> </ItemTemplate> So to convert this I have to use the InstantiateIn method of the ITemplate for the layouttemplate and the ItemTemplate. Data is bound to the itemtemplate using the DataBinding event. My question at the moment is how do I setup the ItemTemplate class and bind the values from the above ListView ItemTemplate. This is what I've managed so far: private class LayoutTemplate : ITemplate { public void InstantiateIn(Control container) { var table = new HtmlGenericControl("table") { ID = "itemPlaceholder" }; container.Controls.Add(table); } } private class ItemTemplate : ITemplate { public void InstantiateIn(Control container) { var tableRow = new HtmlGenericControl("tr"); //first field in row var tableFieldImage = new HtmlGenericControl("td"); var imageLink = new HtmlGenericControl("a"); imageLink.ID = "imageLink"; tableRow.Controls.Add(imageLink); // second field in row var tableFieldTitle = new HtmlGenericControl("td"); var title = new HtmlGenericControl("a"); tableFieldTitle.Controls.Add(title); tableRow.Controls.Add(tableFieldTitle); //Bind the data with the controls tableRow.DataBinding += BindData; //add the controls to the container container.Controls.Add(tableRow); } public void BindData(object sender, EventArgs e) { var container = (HtmlGenericControl)sender; var dataItem = ((ListViewDataItem)container.NamingContainer).DataItem; container.Controls.Add(new Literal() { Text = dataItem.ToString() }); } One of the functions in the ListView just for an example is: public string GetURL(object objArticle) { ArticleItem articleItem = (ArticleItem)objArticle; Article article = new Article(Guid.Empty, articleItem.ContentVersionID); return GetArticleURL(article); } Summary What do I need to do to convert the following into a composite control: 1. <a href="<%# GetURL(Container.DataItem) %>"><%# GetImage(Container.DataItem)%></a> 2. <a href="<%# GetURL(Container.DataItem) %>"> <%# DataBinder.Eval(Container.DataItem, "Title") %> </a>
