I would like to know more about how the ASPNET runtime assigns unique control IDs to the controls on a page. I'm curious because it
doesn't appear to be "fixed"...which causes problems with composite controls which contain controls doing postbacks.
Here's what happened to me: I ...

I posted this in a different group yesterday with no responses, so I'll
try here.
I have a simple control that is in a CS file (not ASCX).  It is derived
from DropDownList like this

I'm trying to create my own custom control based on the textbox, but
with additional properties to specify whether or not the textbox is a
required field, and if its needs to be validated against a regular
expression. I'd also like it to change its backcolor and be focused on

How can I change the tag prefix of a custom control.
My Asp.Net 2.0 custom control tag prefix is cc1.
Thanks,

I am trying to extend the default asp:ImageButton to include an image for an
enabled state and a second image for a disabled state.  I currently did this
by extending the ImageButton class in a custom control, creating a property
for each of these images (EnabledImageUrl, ...

Okay, I'm confused: I have a custom composite control which has several "steps". I've created the DesignerActionList infrastructure
to move between the steps at design time. The methods that control the movement get called, the "step state" gets changed...but the
design surface ...

I have a custom control in a Formview. This custom control consists of a
textbox, a label and some code-behind. The code behind generates a codenumber
in the label based on a database and the entry in the textbox. Everything
works fine. I bind with two properties the textbox and ...

I have a custom composite control whose markup needs to contain child controls, an array property, and simple properties, all as
nested tag elements, e.g.:
<cc1:MyComposite runat="server" id="whatever" SimpleProp1="somevalue">
    <ChildControls>    <-- this is a property collection, of ...

In design-mode, when my databound composite control creates its child controls and adds them to its control collection, the
designers for the newly-created child controls (which are also composite databound controls) don't get called.
Why is that? I thought the designer was always ...

I'm building a custom control which is essentially a customized version of the Wizard control, although it doesn't derive from the
Wizard class. It's designed so that you can add a sequence of a limited number of types of steps to the control (e.g., an
Introduction step, a ...

I used to know how to hijack the last cell of a datagrid when it's
selected but can't seem to with a gridview.  It's been a while, but I
seem to remember adding something like this "</td></tr><tr><td
colspan=4>testinghere</td></tr>" to get another row that I could

I've written a "SmartWizard" class that essentially adds initialization and exit handlers for the individual steps, allowing for
easier control over how a user walks through the wizard.
But I've run into a problem with the design-time support. With a regular Wizard, clicking on a ...

I'm in a bit of a pickle here: I've got some kind of problem involving persisting some complex properties on a custom control, but
because VS2005 SP1 keeps crashing when it encounters the problem I'm at a loss as to how to figure out what's wrong.
Here's a sketch of the custom ...

I have a datagridview column that will contain both editable and
non-editable values. I have set the columns readonly property to true. I
then use the AddRows event to check the value of an hidden column and if
that is false i set a specific cells readonly property in the column ...
