Databinding - Binding Custom Class Property From ASCX Markup?
May 19, 2010I have an ASCX that inherits from a WebControl that has a 'CustomConfiguration' property of type CollectionConfigurationItem. This configuration gets set elsewhere in the code, so by the time it gets to the ASCX it is set up to how I wish to use the data. At this point I'd like to render out another control using this configuration, like so:
<modules:DataModule runat="server" CustomConfiguration="<%# Model.CategoryListConfiguration %>" />
However, breaking into DataModule always results in 'CustomConfiguration' being null, which is the default value for the property. I've tried adding a Bindable attribute to the property but to no avail, and when I set an EventHandler for the DataBinding event on the DataModule it doesn't even get called.
How can I set this custom-class-typed property from the markup or, failing that what's the second-best method of getting this to work?
C# - Extend Control (ASCX) And Access Base Markup File From Subclass Code?
Jan 29, 2010I'm building form validation controls for our C# ASP application. The bulk of the work is handled by a BaseValidator control (subclassing System.Web.UI.UserControl), which also has the markup for the validation output. This is then extended by subcontrols like PasswordValidator, that provides the Validate method and any extra fields needed by that validator control.
(The end goal is to have controls like <uc1:PasswordValidator ControlId="txtPassword" /> which we can plop into any form with minimum duplication.)
However, PasswordValidator.ascx.cs cannot access the form elements defined in BaseValidator.ascx; the only way I've found to do so is to duplicate the markup in each subcontrol's *.ascx file. How can I extend BaseValidator.ascx.cs and access BaseValidator.ascx's markup in the subclass?
MVC :: How To Encapsulate Logic In Ascx Partial View With The Same Efficiency Of Webforms Ascx
Aug 10, 2010I have to build a few ascx partial views in my MVC applications to encapsulate re-usable functionalities as well as archive SOR and SOC. However, I encountered challenge how to encapsulate the business logic that drives MVC ascx views.In webforms, the code behind of an ASCX control can handle a button click event and browser still shows the same page with only one postback. How can I archive the same thing in MVC? When ~/Address/Edit/2 includes an ascx partial view with a button on it that calls another MVC action - let's say ~/ShareController/CommonAction - what is the best way for the CmmonAction to return to the very same view that includes the ascx file?Perhaps I am missing a common pattern in MVC web development?
View 5 RepliesControl Within Ascx Is Null When Ascx Is Added From Codebehind?
Apr 14, 2010I 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 [URL]
Many Ascx-to-one Ascx.cs Error In VS2008?
Mar 16, 2010I'm developing second language support for the site. So I made duplicate .ascx and .aspx files for existing ascx.cs and aspx.cs
Most of the time everything works fine.. but suddenly I'm getting:
Type 'ctrl_car' exists both in 'c:WindowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files
zhdengined072cc729d5698bApp_Web_xdmblegv.dll', and in 'c:WindowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files
zhdengined072cc729d5698bApp_Web_gkptrzo2.dll' (translated from russian)
ctrl_car ctrl = (ctrl_car) LoadControl("car.ascx");
I have few such strings of code... and same error occurs with one of them. But WITHOUT any changes from me with those files. To fix thaat bug for some time I need to delete solution and website folder and reget them from SS. Solution was converted from vs2005.
Web Forms :: How To Inherit .ascx Page To Another .ascx Page
Sep 16, 2010i have made a BaseUserControl.ascx and a ChildUserControl.ascxfile. both have its own code behind file.So what i want, i wanted to inharit ChildUserControl.ascx fileto BaseUserControl.ascx. so whatever in my BaseUserControl.ascx fileshould be visible into the ChildUserControl.ascx,means if i have kept a TextBox in BaseUserControl.ascx should be visibleinto the ChildUserControl.ascx desing view. and it should be accessible into the ChildUserControl.ascx code behind file.
1) Is this possible, if yes then how?
2) if above is possible then How to access BaseUserControl.ascx code behind file into the ChildUserControl.ascx code behind file?
Using Codeblocks Within Usercontrols?
Sep 30, 2010I tried using a codeblock syntax within a property sent to a web user control:
<uc1:MyControl ID="MyControl1" runat="server" SomeProperty="<%= somevalue %>"/>
The user control has the public property SomeProperty declared and also uses code block to display the property value:
<p><% = SomeProperty %></p>
The output on my page is unfortunately
<p><%= somevalue %></p>
And not the actual value. Anyone know of some workaround for this?

Configuration :: UserControls Not Getting Re-compiled?
Nov 22, 2010We deployed a UserControl to our testing server. Then made a change to the UserControl and re-deployed. I cannot get the change to take. We have cycled the ASP.NET server, deleted the file completely and re-copied, and also tried a suggestion to change the web.config in order to force all files to be re-compiled.
I definitely know that we are changing the correct file. At one point, I removed the UserControl file altogether and received the "File not found error" when trying to load the user control. The file IS the correct version on the testing server.

C# - How To Add A Dynamic Number Of UserControls In Page
Feb 25, 2010I have an (almost) empty aspx page and I want to insert a certain number of the same user control in this page.
I tried to add them from the CodeBehind but it seems that the UserControls are completely empty.
In the main page (MainDiv is a div with runat="server"):
protected void Page_Init(object sender, EventArgs e)
{
WebUserControl1 uc = new WebUserControl1();
WebUserControl1 uc1 = new WebUserControl1();
MainDiv.Controls.Add(uc);
MainDiv.Controls.Add(uc1);
}
(it doesn't work if i put this code on Page_Init, Page_Load or Page_PreRender)
UserControl (gw is a Gridview contained in the UserControl):
protected void Page_PreRender(object sender, EventArgs e)
{
if (_data != null)
{
gw.DataSource = _data;
gw.DataBind();
}
}
when I arrive there, gw is null (this.Controls.Count is 0).

View 1 RepliesWeb Forms :: Visibility Of Panels And UserControls?
Mar 9, 2010First off - has any recent .NET / Windows Service Pack / Windows Update changed the behaviour around the Visibility of Panels / User Controls? An area of our site has all of a sudden stopped working. The most recent change that I made was a few weeks ago, I've backed out the change from my development environment, but the issue is still happening.
I'll explain what is happening. I have a couple of forms where the same behaviour is happening, but they follow the same pattern:
On the form there is let's say 2 ASP:Panel controls. In each of these there is a separate ASP:UserControl. When the User first visits the page, they are shown the first Panel and User Control. On this control they complete a couple of steps and click Next. This fires an event on the main page, which hides the first panel and shows the second panel, at least that is what is supposed to happen - and if I debug and step into the code this is what is happening as normal. Except on screen, the first panel is no longer being hidden, so it would appear clicking the Next button does nothing.
I'm at a loss as to what has happening - nothing has changed, and stepping through the code it's working correctly, but the screen is not reflecting what is happening in the code.
My next step is to create an isolated set of test pages to recreate the issue. Will attach when done and investigated, hopefully this will solve it

Feb 15, 2011This is probably embarrassingly easy, but I've having problems getting this to work.
On ResidentAddress.aspx, I have 2 user controls (AppName.ascx and NavButtons.ascx). When a textbox in AppName.ascx has focus, I want to update a hidden input field on NavButtons.ascx with the value of "TRUE". In the codebehind page for NavButtons, I want to see what the value of this hidden input filed is.
This is what I have so far:
NavButtons.ascx
<input type="hidden" id="IpChangeFlag" name="ChangeFlag" runat="server" value="FALSE" />
AppName.ascx
<asp:TextBox ID="txtFirstName" runat="server" onFocus="document.getElementsByName('ChangeFlag').value='TRUE';">
NavButtons.ascx.vb
If IpChangeMade.Value.Trim.ToUpper = "TRUE" Then
MyValue = true
End If
I am unable to change the value of ipChangeFlad. It always has the value of FALSE.
