User Control controls not created when dynamically creating user control
Have created a user control for displaying and editing a dynamically number of values. The user control contains two labels and an edit box. When dynamically loading the user control I get an error when the control itself tries to change setting on the fields within the user control.
Why doesnt this work? It works okay if I dont load it dynamically but create a user-control-instance in the aspx-page but thats no solution.
Here is my code:

I have a gridview with a lot of rows. This means I can't create the the correct controls (like dropdowns) at once but I have to create them once the user wants to edit a row.

lstPersCat.ID = "lstPersCat"
Dim strUserGroups(10) As String
strUserGroups = retUserGroups(CType(gvResults.Rows(e.NewEditIndex).Cells(9).Controls(0), TextBox).Text.ToString)
For i As Integer = 0 To strUserGroups.Length - 1
If Len(strUserGroups(...create and add controls dynamically to dynamically created Table Control

Heres the deal. I have a hierarchal or tree structure of data that needs to be represented in dropdownlists (ddl). The root is a single ddl and the items in the ddl are children of the root. When a child is selected I need to add another ddl to the control collection with it's children as listitems. Its like dropdownlist chaining without knowing the order of the dropdownlists.
Now I know I can use the Page.OnInit method to add the ddl, but since viewstate is not loaded until after OnInit is called I don't have access to the selected child.
Right know I am getting around this by u...Dynamically creating controls in a Table control
Hi I'm using a Table control to create a table in a Webform, however I need to be able to create additional controls within certain cells for instance an ImageButton where I can then build an event handler for each one I dynamically create.
How do I do this, I've been trying add the control to the Controls collection of either the Page or the Table - all with poor results.
Normally I'd add a control into a place holder, but again that's something that I'd need to dynamically create also in each cell I suppose...?
Thanks in advance.

I have a interface with a treeview and a gridview. The gridview has two templatefields that handles insert/update/deletes. The gridview is handling editing of different tables so I create the other columns in the gridview dynamically as boundfields. The user selects the table to edit in the treeview.
The problem I am having happens when the user selects a table to edit the second time. The code that executes removes all bound fields, (dynamically added when user selected the first table in the treeview), but not the two template fields, and then adds boundfields specifi...Dynamic Slave Controls
I am working a solution to enhance slave controls. I have created a proof of concept based on the 2.04 code base that shows how to load slave controls without switching to the admin view. I have included a sample module that contains 3 view controls. Each control has a row of buttons that can be used to load one of the other 2 controls. (and no I am not using panels.) The default control has a drop down of other instances of the dynamic control that exist on the current tab. Using the module communicator you can raise an event from one control that tells another instance of the module what c...Adding dynamically created controls to Wizard control.
