  • I need to know how to create a custom webform template in ASP.NET that allows me to pick a master pa

    - by Pete
    Using Visual Studio 2008, I need to create a custom web form that when picked acts like the web content form, by providing a dialog that lets you pick a master page. I have looked through the webform.zip template and thought I had a clue, but trying different combinations has baffled me as it either doesn't appear or doesn't work. Also when you set the project type to Web and sub project type to CSharp it doesn't appear, so I don't know if this part of the cause, because I would of hoped that the SupportsMasterPage element would of caused this dialog to appear, if it is a web item, but no luck. Frown Any ideas? p.s. I have used my googling resources to the maximum so unsure what to do.

  • How do I set up for sharing code (ASP.NET) across multiple domain names?

    - by Scott J.
    I have built a website and now the customer wants to split it between three different domains. What is the best way to do this? This is what I have so far. c:/website1/ points to www.website1.com c:/website1/vd1/ points to www.website2.com c:/website1/vd2/ points to www.website3.com The webhost I'm working with has done it the following way, but now I'm getting a bunch of errors that seems like it's not seeing the App_code folder. Do I need to make a lot of changes? How does this affect the location references?

  • What alternatives are there for asp.net forms authentication?

    - by Eytan Levit
    Hi, We are developing a web app that will have a pretty complex user and permission system. The general idea is that we have 3 levels of security: a simple user - that can only access basic data that is in a data repository a manager - that can open up data repositories a superuser - that can open up repository factories. each repository contains various data types(text, images, etc etc). We are looking for authentication methods that will allow us: 1. Scalability. 2. Customization. 3. To create permissions that will effect the GUI + deny access to certain pages. 4. To create predefined roles - that will allow for easy setup of new users. 5. To create custom roles for specific users - allowing them permission sets that are different from the predefined roles. Thanks in advance

  • How can I resolve ASP.NET "~" app paths to the website root without a Control being present?

    - by jdk
    I want to Resolve "~/whatever" from inside non-Page contexts such as Global.asax (HttpApplication), HttpModule, HttpHandler, etc. but can only find such Resolution methods specific to Controls (and Page). I think the app should have enough knowledge to be able to map this outside the Page context. No? Or at least it makes sense to me it should be resolvable in other circumstances, wherever the app root is known. Update: The reason being I'm sticking "~" paths in the web.configuration files, and want to resolve them from the aforementioned non-Control scenarios. Update 2: I'm trying to resolve them to the website root such as Control.Resolve(..) URL behaviour, not to a file system path.

  • How to convert .NET WPF application to Windows Forms?

    - by Janusz
    Hello, We have created a beautifully designed .NET WPF desktop application. We are installing the application with InnoSetup , and if .NET 3.5 is not present, it automatically installs it. However, the package to download .NET 3.5 is huge and we found out that about 30% of users do not finish instalation due to this. The obvious solution is to recode everything into .NET 1.1 with Windows Forms but its a major development which would take few weeks. Also, we would then face dilemma if to support both versions (and use innosetup to choose the right one) or just ditch WPF all together. Is there any easy way how to convert WPF to Windows Forms? Or do we have any alternative options to consider? Thank you!

  • Gridview looses ItemTemplate after columns are removed

    - by Middletone
    I'm trying to bind a datatable to a gridview where I've removed some of the autogenerated columns in the code behind. I've got two template columns and it seems that when I alter the gridview in code behind and remove the non-templated columns that the templates loose the controls that are in them. Using the following as a sample, "Header A" will continue to be visible but "Header B" will dissapear after removing any columsn that are located at index 2 and above. I'm creating columns in my codebehind for the grid as a part of a reporting tool. If I don't remove the columns then there doesn't seem to be an issue. <asp:GridView ID="DataGrid1" runat="server" AutoGenerateColumns="false" AllowPaging="True" PageSize="10" GridLines="Horizontal"> <Columns> <asp:TemplateField HeaderText="Header A" > <ItemTemplate > Text A </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> Header B </HeaderTemplate> <ItemTemplate> Text B </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> For i = 2 To DataGrid1.Columns.Count - 1 DataGrid1.Columns.RemoveAt(2) Next EDIT So from what I've read this seems to be a problem that occurs when the grid is altered. Does anyone know of a good workaround to re-initialize the template columns or set them up again so that when the non-template columns are removed that hte templates don't get removed as well?

  • Why Can't I store XML in ASP.NET ListBox Value?

    - by mcass20
    Hello, Why does this work: ListItem item = new ListItem(); string value = lstAvailExtPropsToFilter.SelectedItem.Text +" = "+ txtExtPropToFilter.Text; string text = lstAvailExtPropsToFilter.SelectedItem.Text + " = " + txtExtPropToFilter.Text; item.Text = text; item.Value = value; lstExtPropsToFilter.Items.Add(item); But not this: ListItem item = new ListItem(); string value = string.Format("<key>{0}</key><value>{1}</value>", lstAvailExtPropsToFilter.SelectedItem.Text, txtExtPropToFilter.Text); string text = lstAvailExtPropsToFilter.SelectedItem.Text + " = " + txtExtPropToFilter.Text; item.Text = text; item.Value = value; lstExtPropsToFilter.Items.Add(item);

  • In asp classic: How can I make sure that a variable can be cast as an int?

    - by Tchalvak
    The following function was suggested to me: ' Defines a forced casting function, which "casts" anything that it can't detect as a number to zero. Function MakeInteger(val) If IsNumeric(val) Then MakeInteger = CInt(val) Else MakeInteger = 0 End If End Function Unfortunately there appear to be some things that return true for IsNumeric() but still can't be cast as an int. Is there any better check to use?

  • ASP.NET how can access public properties of MasterPage from external Class ?

    - by eugeneK
    Why i can't access MasterPage's public property (MessagePlaceholder) from other Class (Errors) ? my master page code behind using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class MyMasterPage : System.Web.UI.MasterPage { public string MessagePlaceholder { get { return messagePlaceholder.InnerHtml; } set { messagePlaceholder.InnerHtml = value; } } protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { messagePlaceholder.InnerHtml = Errors.getMessage(); } } } my Errors Class public static string getMessage() { HttpContext c = HttpContext.Current; string messageType = ""; if (c.Session["errorMessage"] != null) { messageType = "errorMessage"; } else if (c.Session["successMessage"] != null) { messageType = "successMessage"; } if (!string.IsNullOrEmpty(messageType)) { StringBuilder userMessageSb = new StringBuilder(); userMessageSb.Append(string.Format("<div id=\"{0}\" title=\"{1}\">{2}</div>", messageType, messageType.Replace("Message",string.Empty), c.Session[messageType])); // fix so message will not re-appear c.Session.Remove(messageType); messageType = userMessageSb.ToString(); } return messageType; } public static void setSuccess(string successMessage, bool isRedirect) { HttpContext.Current.Session["successMessage"] = successMessage; } public static void setError(string errorMessage, bool isRedirect) { HttpContext.Current.Session["errorMessage"] = errorMessage; if (!isRedirect) { ((HttpContext.Current.CurrentHandler as System.Web.UI.Page).Master as MyMasterPage).MessagePlaceholder = getMessage(); } } this is how i set error if (true) { Errors.setError("this is an error demo", false); return; } or with redirect after error if (true) { Errors.setError("yet another error", true); Response.Redirect("~/error.aspx"); }

  • Why ASP.NET menu control ignores roles in Web.sitemap?

    - by MainMa
    Hi, I have a website with a menu based on sitemap. ActiveDirectoryRoleProvider is a custom class. securityTrimmingEnabled of sitemap provider is set to true. Now, nevertheless the roles set in the sitemap file, site menu displays every sitemap entity. So for example if I have in sitemap a node with roles="*", a second one with roles="Administrators" and a third one with roles="Foo" and I login as a member of Administrators group but not Foo group, the site menu will display all three items. On the other hand, if I have a node which does not specify roles attribute but has children, this node will never be displayed. If I put: <%= HttpContext.Current.User.IsInRole("Administrators") ? "Admin" : "Not admin"%> <%= HttpContext.Current.User.IsInRole("Foo") ? "Foo" : "Not foo"%> before the menu, it displays that I'm Admin, but Not foo, which is just fine. So if it knows that I'm Admin but Not foo, why does it continue to display Foo's sitemap nodes? Note: changing authorizations has no effect on the menu. It continues to show every item, even for the pages I'm unable to access.

  • Model View Presenter plus ASP.NET Web Service; where does the asmx live?

    - by Dirk
    I've been slowly transitioning from a traditional web forms architecture to the MVP pattern (Passive View). So far, it's been fairly easy to implement b/c the views I've dealt with have all employed a classic PostBack model. However, I've come across my first view that will refresh portions of itself via web services. I can't grok where the web service should live (Presenter I think) or how to expose that asmx end point to my View while still maintaining the clean separation of concerns/testability that MVP affords me. I've searched far and wide for some examples on how this might be implemented and have come up with nothing. Please help!

  • How to handle null return from custom HttpHandler in asp.net?

    - by Campos
    I'm using a custom ashx HttpHandler to retrieve gif images from a database and show it on a website - when the image exists, it works great. However, there are cases when the image will not exist, and I'd like to have the html table holding the image to become invisible so the "image not found" icon is not shown. But since the HttpHandler is not synchronous, all my attempts checking for image size at Page_Load were frustrated. Any ideas on how this can be accomplished?

  • Why does my ASP.NET user control's field value reset to 0?

    - by Innogetics
    In the code below, why does the groupId value reset to 0 during Page_Load event? Maybe perhaps the AccountGrid created with groupId 1 is not the one that is loaded to the page? public partial class AccountGrid : System.Web.UI.UserControl { int groupId = 0; public AccountGrid() { } // an aspx page creates AccountGrid with "new AccountGrid(1)" public AccountGrid(int groupId) { this.groupId = groupId; } protected void Page_Load(object sender, EventArgs e) { DataAccessFacade facade = new DataAccessFacade(); // groupId resets to 0 here... grdAccount.DataSource = facade.GetAccountsByAccountGroupId(this.groupId); grdAccount.DataBind(); } } In my page, I have public partial class Default : System.Web.UI.Page { public Default() { } public void Page_Load(object sender, EventArgs e) { ctlAccountGrid = new Views.Controls.Account.AccountGrid(1); // should I do databind? ctlAccountGrid.DataBind(); } }

  • A Better way? Finding ASP.NET controls, finding their id

    - by CSharp
    I have a method that finds all the controls, iterates through them, determines if they are a textbox,drop down list, etc.. retrieves their ID name, and depending on the ID name it will set a boolean statement (thus I would know if that section of the form is complete, and will email to a certain group of people) unfortunetly this is done with too many if statements and was wondering if I could get some help making this more manageable protected void getEmailGroup() { Control[] allControls = FlattenHierachy(Page); foreach (Control control in allControls) { if (control.ID != null) { if (control is TextBox) { TextBox txt = control as TextBox; if (txt.Text != "") { if (control.ID.StartsWith("GenInfo_")) { GenInfo = true; } if (control.ID.StartsWith("EmpInfo_")) { EmpInfo = true; } } } if (control is DropDownList) { DropDownList lb = control as DropDownList; if (lb.SelectedIndex != -1) { if (control.ID.StartsWith("GenInfo_")) { GenInfo = true; } if (control.ID.StartsWith("EmpInfo_")) { EmpInfo = true; } } } } } }

  • Can I create an ASP.NET ImageButton that doesn't postback?

    - by Giffyguy
    I'm trying to use the ImageButton control for client-side script execution only. I can specify the client-side script to execute using the OnClientClick property, but how do I stop it from trying to post every time the user clicks it? There is no reason to post when this button is clicked. I've set CausesValidation to False, but this doesn't stop it from posting.

  • How do I restrict the WCF service called by an ASP.NET AJAX page to only allow calls for that page?

    - by NovaJoe
    I have an AjaxControlToolkit DynamicPopulate control that is updated by calls to a WCF service. I know I can check the HttpContext in the service request to see if a user of the page (and thus, the control) is authenticated. However, I don't want anyone clever to be able to call the service directly, even if they're logged in. I want access to the service to be allowed ONLY to requests that are made from the page. Mainly, I don't want anyone to be able to programatically make a large number of calls and then reverse-engineer the algorithm that sits behind the service. Any clever ideas on how this can be done? Maybe I'm over-thinking this? Thanks in advance.

  • Where does ASP.Net get its rendered IDs from?

    - by NeilD
    Hi, I've inherited a project with some nasty JavaScript that depends on hard coded object ids. i.e. There are lots of places where it does things like this var magazine = document.getElementById('repModuleDisplay__ctl3_chkCats_0'); When the page renders in my UAT environment, the HTML looks like this, and everything works OK. <input id="repModuleDisplay__ctl3_chkCats_0" type="checkbox" name="repModuleDisplay:_ctl3:chkCats:0" ... etc However, when I put it on my Production environment, the HTML is suddenly rending like this: <input id="repModuleDisplay_ctl03_chkCats_0" type="checkbox" name="repModuleDisplay$ctl03$chkCats$0" ... etc The difference in ids means that the JavaScript can't find the Element, and fails. In an ideal world, I'd scrap the buggy JavaScript and do it again properly, but for a quick fix, I'd like to know what is causing the difference in rendering between the two environments. Does anyone have any ideas? Thanks, Neil
