I'm dynamically adding a calendar extender like so:

When a postback occurs I get the following error:

I'm trying to create a calendar extender dynamically on my application. For that i am using the following code:
[Code]....
THe problem is that i'm having a runtime exception, on the OnPreRender of the ExtenderControlBase.cs saying that "A control with ID "filtrodatainicio" could not be found. I'm pretty sure the problem resides in the fact that i'm creating both the text box and the extender dynamically but i can't quite figure out what should i change to make this work.

Is there any workaround here?

[Code]....
When I run the site with this code I get the following error:Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors.Parameter name: element
I thought it might be because the target control ID changes during compilation so i tried to find the labels in the Page_InitComplete method with this:[Code]....
The expression in the FindControl argument is what the id of the label looks like when i view source in my browser after running the page.I also tried to use the popup control's DynamicControlID property, but im not sure what the DynamicServiceMethod is for.

is anybody interesting in share and join to develop callback web controls. My purposes is lower unsynchronized page development cost. I have developed a base class and a set of common controls. Currently, they allowed to be loaded dynamically in a control or ASCX via callback event using sample server side code. Control library code will automatically register javascript and render it on client browser. These controls worked fine in both callback and postback. To load dynamically from an ASCX file.
'ascx1.ascx contain some callback-able controls
Private Function LoadAscx_DuringCallback(Optional ByVal RenderMe As Boolean = False) As String
Dim rt As String = ""
div1.Controls.Clear()
Dim c As Control = LoadControl("~/Test2/ASCX/ascx1.ascx")
c.ID = "ascx1"
div1.Controls.Add(c)
If RenderMe Then rt = CallbackManager1.RenderControlHelper(c)
Return rt
End Function
Or to load dynamically as a control
'c is a callback-able TextBox
Private Function LoadControl_DuringCallback(Optional ByVal RenderMe As Boolean = False) As String
Dim rt As String = ""
div1.Controls.Clear()
Dim c As New ACT360_CallbackControls.ZYH.TextBox
AddHandler c.KeyUp, AddressOf TextBox_KeyUp
AddHandler c.GetFocus, AddressOf TextBox_GetGocus
div1.Controls.Add(c)
If RenderMe Then rt = CallbackManager1.RenderControlHelper(c)
Return rt
End Function
how can change target control ID of an autocomplete Extender without refreshing page or using update panel

I am using ASP.NET 2.0 with VB. In design view of grid, i have one textbox in its template field. I also have one Ajax Calender Extender and FilteredTextBox Extender. I have set target controlId of both calender and filteredtextbox extender equal to that textbox. Now dynamically i dispose one of the extender from that textbox. everything works ok. But once my page reloads it takes the original design image, means both extenders are being set to that textbox.

View 1 RepliesI am using ASP.Net 3.5 with AJAX. I have a situation where I create a table dynamically depending on user input. One column of the table will contain a small image. Right now, it takes a click of the image to show a larger view in a new window. I would like to change it so that when the mouse moves over the image a HoverMenu pops up with the enlarged image view. I have done this with image controls placed on the page at design time where only the image's url is dynamic. How can this be done if image conrtol is created dynamically in the back-end code?
View 5 RepliesHow would I create an AJAX Accordion pane from the code behind? I would like the user to be able to click a button to add a new pane to an existing accordion control. However, I can only seem to create one new pane because clicking the button after that causes the old pane to be overwritten. I have this in the button click event:

A new pane is created with the correct content, but then it keeps getting overwritten. I've looked around and have seen similar problems but no answer.

i have been trying to create controls dynamically on my web page using the StringBuilder class..and i dont quite seem to get through...
i am trying to do this...
StringBuilder sbTest = new StringBuilder(string.Empty);
sbTest.Append("<input type="text" id="txt1" runat="server" />");
Response.Write(sbTest.ToString());
The page for sure displays a TextBox on the browser which is easily accessible through JavaScript...but what i want is the control to be available on the Server Side too...so that when the page is posted back to the server i can easliy obtain the value that has been entered by the user into the textbox.
When i try to submit the page which has modal popup extender,popup extender becomes visible! How can i avoid this?

I want to create custom control (let's name it DesignPanel) that will allow user to design his own webpage structure that would be stored in a sitemap file. This Design Panel will have child controls inside ( SiteElement). User will build page strcture by connect Site Elements, customize them ( like change name) and add new ones.
This last point is main issue for me. Should I add those Site Element controls dynamically like DesignPanel.Controls.Add(new SiteElement()) in UpdatePanel control or there is better approach ( adding them to DOM structure by javascript, something diffrent)?
