Web Forms :: Dynamic Usercontrol Loading When Using ParseControl() Method In VS2008

Oct 12, 2010

In the process of migrating an old VS2003 web app to VS2008, I'm running into this issue and haven't been able to find a resolution. Sample code: "Default.aspx" has a PlaceHolder(ToolHeader). In the Page_Load(), we dynamically load a user control passing in the virtual path to a helper method [public Control ParseUserControl(string virtualPath)]. This reads the content from the physical path, returns
a Control from ParseControl() method. I immediately get the following error when I open the default.aspx page in browser.

Parser Error

Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Could not load type 'DynamicUC.UcControl'.

Source Error:
Line 1: <%@ Control AutoEventWireup="true" CodeBehind="UcControl.ascx.cs" Inherits="DynamicUC.UcControl"&nbsp; %>

Can't figure out why it can't load the type. Namespaces are looking right. I try removing the Inherits="DynamicUC.UcControl" attribute from the "ucControl.ascx", it loads the page fine. Also, this control is a simple one and has no code behind. There are others with actual code behind. They won't work if I remove the Inherits attribute.

Web Forms :: Dynamically Loading UserControl From DLL?

Nov 15, 2010

I would like to load UserControl dynamically from DLL in the bin directory.

The dll contains several usercontrols which dynamically create webcontrols within them.

I do not have Virtual Path of the UserControls to use in LoadControl(String virtualpath) and LoadControl(Type, object[]) does not work(why the heck is it there in the first place anyways).

provide me some sample code which takes either the path of dll or assembly name "ServerControls" to load usercontrol "UserControl1" dynamically into placeholder "PlaceHolder1"

Forms Data Controls :: Formview - ParseControl And OnTextChanged

Sep 20, 2010

I have a formview with some templates. This is hooked up using objectdatasource. To the default layout I add some additional Label/Textboxes dynamically based on metadata in a database. I create the additional controls in the ItemCreated event using ParseControl on a Placeholder and populate the values in the DataBound event. This all works fine.

I have been modifying the extra textboxes using a ForEach loop in the ItemUpdated and ItemInserted events of the main formview. However this modifies each textbox regardless of whether the textbox has changed. What I want is to only modify the textbox if it has changed. I have tried to hook up OnTextChanged for the additional textboxes (using ParseControl) but the handler is never getting called. I thought maybe I was making a mistake in the execution order of the page but now I'm wondering whether ParseControl isn't hooking up the event handler correctly? Anyone come across this?

C# - Dynamically Loading Usercontrol In Updatepanel?

Feb 16, 2011

So I'm trying to dynamically load a usercontrol into a placeholder in another usercontrol inside a updatepanel.

basically I've got this markup:

<asp:UpdatePanel ID="upPopup" runat="server">
<ContentTemplate>
<UC:Popup runat="server" ID="UC_Popup" />
</ContentTemplate>
</asp:UpdatePanel>

And then this markup inside that usercontrol (Popup):

<div id="modal">
<asp:PlaceHolder ID="phPopupPlaceholder" runat="server"></asp:PlaceHolder>
<asp:Label ID="lblModal" runat="server"></asp:Label>
</div>

In the codebehind of the popup usercontrol I have:

public void Show(UserControl control) {
this.phPopupPlaceholder.Controls.Add(control);
this.lblModal.Text = "Loaded";
}

And I call this show method elsewhere with:

Popup.show(new MyUserControl());

Nothing loads into the placeholder though.

But in the show method I can load regular server-controls fine like this:

this.phPopupPlaceholder.Controls.Add(new Label(){ Text = "Label!" });

Can anyone explain to me why regular controls are loaded fine, but my usercontrol isn't loaded?

C# - Loading Usercontrol On Runtime And Reloading The Page?

Jan 29, 2011

On my page I have a placeholder where I load a usercontrol when I select an item in dropdownlist.

protected void ddlLoadCtr_SelectedIndexChanged(object sender, EventArgs e)
{
Control userControl = LoadControl("../AleSettings1.ascx");
plchldSettingsControl.Controls.Add(userControl);
}

If I press F5 (IE) after user control was rendered, I get IE's warning window that IE needs to resend the information....
How can I prevent it and why does it happen?

UPDATE:Maybe there is another approach? I want to load specific control (with it's markup) when user selects it from the dropdownlist.
if a postback is made the control shouldn't disappear(only if another control was selected from the dropdownlist) Everything is inside update panel!

Custom Web UserControl (vs2008 C#) - "not A Known Element" When Placed?

Jan 15, 2010

I created (vs2008 C#) an "asp.net web server control" project. I then remove the default .cs and replace it with an "asp.net web server control" cs file which has a default name of WebCustomControl1.cs. I named the project CCContainer and renamed the .cs file as CCContainerA.cs, so the class name is CCContainerA. I then create a new (VS2008 C#) web application in which I add my custom control. After compiling CCContainer to CCContainerA.dll I create a reference to this dll in the web app, and add CCContainerA.dll to my web app's toolbox. When I drag my custom control to the webform I automaticall get this directive line:

I have a usercontrolthat has to do a lot of DB calls which can take a few seconds making the page slow to load. Ideally I'd like the main page to load straight away and then the usercontrol content appear when it is ready.

Web Forms :: Calling A Public Method On Aspx Page From A Usercontrol

Sep 7, 2010

I have a problem with calling a method on a aspx page from a usercontrol.

The case is: I have 1 main page with 5 usercontrols, when something goes wrong in the code I want to display the error message in a Modalpopup Extender. I can create for each usercontrol a different modalpopup extender but isn't much easier when I make 1 popup in the aspx page. But the problem is: How should I call a method in the aspx page that open the popup?

I have search several hours on the internet but can't find anything useful.

Web Forms :: Nested Dynamic UserControl Drops Value Of Textbox - Not Dropdownlist?

Aug 12, 2010

I have a webUserControl that is nested inside of another dynamically loaded usercontrol. The nested user control (harddrive) can have multiple iterations, see below for hierarchy When a postback occurs the value in the dropdownlist inside of the nested userControl is saved, but the data in the textboxes is lost. any ideas?

Hierarchy:
insert.aspx
[^--loads] asset.ascx
[^--- loads] harddrive.ascx -- there can be multiple instances of this control inside of the asset.ascx user control
