  • How to get the value of a SELECT HtmlElement in C# webBrowser control

    - by AndrewW
    Hi, In a C# WebBrowser control, I have generated a SELECT HtmlElement with a number of OPTION elements using w.RenderBeginTag(HtmlTextWriterTag.Select). I need to get the value of the select when the user changes it, and so added an event handler in the WebBrowser DocumentCompleted event. private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { .... webBrowser1.Document.GetElementById("id_select_0").AttachEventHandler("onchange", new EventHandler(ddSelectedIndexChanged)); .... } protected void ddSelectedIndexChanged(object sender, EventArgs e) { .... } The event handler does get called, but the sender parameter is null and e is empty. Does anyone know how to overcome this problem? Andrew

  • JavaScript Intellisense with Telerik in ASP.NET Master Page Project with VS 2010

    - by Otto Neff
    Today I was looking for a solution to get finally the JScript/Javascript/jQuery Intellisense Featureworking with my ASP.Net Webform Project to work. I found some good articles: - JScript IntelliSense Overview- JScript IntelliSense: A Reference for the “Reference” Tag- Enabling JavaScript intellisense in VS.NET 2010 to work with SharePoint 2010- Rich IntelliSense for jQueryBUT, all of suggested solutions did not work right with my Master Page based Visual Studio 2010 Solution.Only with physical Javascript Files (Telerik includes certain Javascript Files like jQuery as Ressource) or/andconfigure always a new ASP.NET Scriptmanager / RadScriptManager on every page derived from the Master Page, wasn't exactly what I was looking for. So I came up with the following simple Solution, to Trick VS2010and still have the Project running with multiple runat="server" Scriptmanagers. In short:- New ASP.NET control derived from ScriptManager with emtpy overwritten OnInit() to use it as emtpy wrapper for VS2010. In detail:New RadScriptManager Classusing System; using System.Collections.Generic; using System.Linq; using System.Web; using Telerik.Web.UI; namespace IntellisenseJavascript.Controls { public class IntelliJS : RadScriptManager { protected override void OnInit(EventArgs e) { } protected override void OnPreRender(EventArgs e) { } protected override void OnLoad(EventArgs e) { } protected override void Render(System.Web.UI.HtmlTextWriter writer) { } public override void RenderControl(System.Web.UI.HtmlTextWriter writer) { } } } web.config<configuration> ... <system.web> ... <pages> <controls> <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI, Version=2011.3.1115.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4"/> <add tagPrefix="VSFix" namespace="IntellisenseJavascript.Controls" assembly="IntellisenseJavascript"/> </controls> </pages> ...

  • webbrowser control on form2 vb windows application

    - by user228058
    Hi, I have a vb windows application with 2 forms, where form2 is called from form1 using form2.showdialog() I added a web browser control to form2, and I'm getting the following error at the point where form2 is called: Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it. I tried: 1) adding STAThread() to the form_load() 2) I added a module to my application, and created a sub main(), with the STAThread attribute applied to it 3) I marked the sub startup() with STAThread() And none of this helped. Any tips on how to get around this issue? Thanks, rcpg

  • Render a user control ascx

    - by Jeremy
    I want to use an ascx as a template, and render it programatically, using the resulting html as the return value of an ajax method. Page pageHolder = new Page(); MyUserControl ctlRender = (MyUserControl)pageHolder.LoadControl(typeof(MyUserControl),null); pageHolder.Controls.Add(ctlRender); System.IO.StringWriter swOutput = new System.IO.StringWriter(); HttpContext.Current.Server.Execute(pageHolder, swOutput, false); return swOutput.ToString(); This all executes, and the Page Load event of the user control fires, but the StringWriter is always empty. I've seen similar code to this in other examples, what am I missing?

  • Use ASP.Net server control code generation from .ashx

    - by Matt Dawdy
    I'm trying to take an existing bunch of code that was previously on a full .aspx page, and do the same stuff in a .ashx handler. The code created an HtmlTable object, added rows and cells to those rows, then added that html table the .aspx's controls collection, then added it to a div that was already on the page. I am trying to keep the code in tact but instead of putting the control into a div, actually generate the html and I'll return that in a big chunk of text that can be called via AJAX client-side. HtmlTable errors out when I try to use the InnerHtml property (says it isn't supported), and when I try RenderControl, after making first a TextWriter and next an HtmlTextWriter object, I get the error that Page cannot be null. Has anyone done this before? Any suggestions?

  • What Source Control?

    - by Hein du Plessis
    I desperately need source control to manage projects between more than one developer. A long time ago I used Visual Source Safe and it worked quite well. Can anybody recommend a free substitute? I have the following basic requirements: I need to host the repository on my own server. I do not want extra clutter within my source files, like CVS does. I need proper check in / check out, so that nobody can change a module until I've checked it back in. I don't want / need source code merging / branching. We use Delphi for web development, so many html files, images, sql files, etc. Any recommendations?

  • Installing a source control without admin rights

    - by Simon T.
    I'm forced to use SourceSafe at my job. There is no way this is going to change. I would like to use another source control for my own need in parallel. I want to be able to keep an history of my modifications, branch easily and merge. I can install any application that doesn't requires admin rights. I cannot install Python or anything that integrates in File Explorer. I'm not much of a command line guy so a GUI is a must. I managed to install Mercurial but not TortoiseHG. There is a chance msysgit would install but the GUI isn't very good. Any suggestions?

  • DragDrop-Support of PictureBox-Control

    - by Effdee
    After some searching i figured out how dragdrop is implemented for a picturebox. But there is one thing - the (inherited of course) allowdrop property isn't accessible from code or property window of picturebox class. So to make it work i added following line to my form-load: ((Control)pictureBox1).AllowDrop = true; Why do i have to do that? In msdn it says: "This API supports the .NET Framework infrastructure and is not intended to be used directly from your code." Any explanation appreciated and sorry for my grammar ;)

  • Industry Reports on Source Control Tools

    - by Kent Boogaart
    Hi, I'm looking for independent industry reports that compare and contrast the various source control tools out there. In particular, I care about Clearcase vs Sourcesafe vs SVN, but if the report includes other SCM systems that's fine. I need this for a client who wants to get a feel on exactly what they stand to gain switching to SVN (yes, from Clearcase and VSS). In other words, something I can use to sell it to their business. I'm hoping some case studies have been done on developer productivity with these tools and resultant reports made freely available. Thanks, Kent

  • Control within ascx is null when ascx is added from codebehind

    - by Snoop Dogg
    I am having difficulties how to construct my question, but if I have to put it simply the situation is that I have categories of products. I have an aspx with a repeater on the left that lists the categories. And I want the products to be listed on the right. Category number is variable so I made an ascx with a DataList in it. When I try to do foreach category, ascx = new ascx(); then the DataList within this ascx control is null. ps: what I want to do is to preload all the products (thre is not much) and hide the divs and fadein fadeout them using jQuery when a category div is clicked. rightnow it is using jQuery.load(); and I don't like how the images load, cuz they download from top to bottom. Progressive gifs alsdo not an option. site demo is here http://techlipse.net/test/ledart Thanks a lot in advance...

  • Choosing a source control system: logical next steps after VSS

    - by Dave
    I've been using Git for the past few months and love it. I looked into how to host it in a corporate environment. Considering a 10 person team who use Visual SourceSafe, programming in Coldfusion, Powerbuilder, PHP and a bit of .NET, I found, to my surprise, that the Git 'server' tooling is still fairly rudimentary. http://stackoverflow.com/questions/1761054/git-in-a-company-hosting-own-server Question Apart from SVN, what other source control options would be a logical next step after VSS? Paid options are fine. Something with nice tooling, that isn't scary would be great :-)

  • Neither IE or Firefox respects the control values that are output

    - by Luke Rohde
    I'm writing a survey designer asp.net mvc. It has buttons to move questions up and down. The buttons post the whole form back and the affected questions are swapped on the server. When the form returns the only thing that is changed are the values for each survey question. Both firefox and IE seem to ignore this change. Nothing is persisted to the database (until save) and url doesn't change so the post just returns the same view but I've stepped through my code to ensure the sequence of values being rendered in the view reflects the swap which is ok. However "view - source" doesn't show the change suggesting caching issue (maybe auto complete). I've tried autocomplete="off" in my form. Response.Cache.SetNoStore(); in my global.asax [System.Web.Mvc.OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")] before my controller and the following in my page header NOTHING!!! This must be real common. Anyone got a clue?

  • Procedures before checking in to source control?

    - by Mongus Pong
    I am starting to get a reputation at work as the "guy who breaks the builds". The problem is not that I am writing dodgy code, but when it comes to checking my fixes back into source control, it all goes wrong. I am regularly doing stupid things like : forgetting to add new files accidentally checking in code for a half fixed bug along with another bug fix forgetting to save the files in VS before checking them in I need to develop some habits / tools to stop this. What do you regularly do to ensure the code you check in is correct and is what needs to go in? Edit I forgot to mention that things can get pretty chaotic in this place. I quite often have two or three things that Im working on in the same code base at any one time. When I check in I will only really want to check in one of those things.

  • WPF Control Toolkits Comparison for LOB Apps

    In preparation for a new WPF project Ive been researching options for WPF Control toolkits.  While we want a lot of the benefits of WPF, the application is a fairly typical line of business application (LOB).  So were not focused on things like media and animations, but instead a simple, solid, intuitive, and modern user interface that allows for well architected separation of business logic and presentation layers. While WPF is mature, it hasnt lived the long life that Winforms has yet, so there is still a lot of room for third party and community control toolkits to fill the gaps between the controls that ship with the Framework.  There are two such gaps I was concerned about.  As this is an LOB app, we have needs for presenting lots of data and not surprisingly much of it is in grid format with the need for high performance, grouping, inline editing, aggregation, printing and exporting and things that weve been doing with LOB apps for a long time.  In addition we want a dashboard style for the UI in which the user can rearrange and shrink and grow tiles that house the content and functionality.  From a cost perspective, building these types of well performing controls from scratch doesnt make sense.  So I evaluated what you get from the .NET Framework along with a few different options for control toolkits.  I tried to be fairly thorough, but know that this isnt a detailed benchmarking comparison or intense evaluation.  Its just meant to be a feature set comparison to be used when thinking about building an LOB app in WPF.  I tried to list important feature differences and notes based on my experience with the trial versions and what I found in documentation and reference materials and samples.  Ive also listed the importance of the controls based on how I think they are needed in LOB apps.  There are several toolkits available, but given I dont have unlimited time, I picked just a few.  Maybe Ill add on more later.  The toolkits I compared are: Teleriks RadControls for WPF since I had heard some good things about Telerik Infragistics NetAdvantage WPF since both I and the customer have some experience with the vendors tools WPF Toolkit on codeplex since many of my colleagues have used it Blacklight codeplex project which had WPF support for the Tile View control  (with Release 4.3 WPF is not going to be supported in favor of focusing only on SilverLight controls, so I dropped that from the comparison) Click Here to Download the WPF Control Toolkits Comparison Hopefully this helps someone out there.  Feel free to post a comment on your experiences or if you think something I listed is incorrect or missing.  Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • I want to version control my entire slice

    - by Tom
    I'm renting a slice (i.e., a VPS) from Slicehost. I've a spent a day or two filling up /usr with my favorite packages, /etc with configs and init scripts, and so on. Now I want to: save this whole setup somewhere (e.g., to load onto another machine). see what changes I've made to which files revert changes, tag revisions, and all that other good version control stuff Saving a disk image gives me (1), but not (2) and (3). Using Subversion (svn import / svn://someotherhost) might give me all three, but I expect problems if I actually try to check a project out into / and maintain .svn directories in root-owned areas. And to load my setup onto a fresh slice, I'd need to install an svn client on it first. Is there a good way to do what I want to do?
