CheckboxList PreRender

[Nehal Shah]

The PreRender event on a CheckboxList never seems to fire. Anyone else
having this problem? Is this a bug or am I doing something wrong?

Thanks,
Nehal

Hi Nehal,

As I understand, we can reproduce the problem with the following steps.

1. Create a default web application in VS.NET 2003.

2. Put a Button control and a CheckBoxList control on the webform.

3. Add the event handlers for the Button control and the CheckBoxList
control.
...
private void CheckBoxList1_PreRender(object sender, System.EventArgs e)
{
Response.Write("CheckBoxList1_PreRender");
}

private void Button1_PreRender(object sender, System.EventArgs e)
{
Response.Write("Button1_PreRender");
}
...
4. Build and Run the application. The PreRender of the CheckBoxList control
does not fire.

I am researching on this issue now. If I have misunderstood your concern,
please feel free to let me know.

Yes, those were the steps I followed although I used a textbox instead of a
button.

Thanks for checking into it. At least I know I'm not doing something wrong.

I figured out a workaround. I overrided the Render method and moved the
code from the PreRender event procedure to it. Of course, I have to call
MyBase.Render afterwards.
