raising post back for a custom server control

11/18/2004 7:22:17 PM

0/0

Hello,

I am writing custom server control that is part of a page that has many of other server controls.
Now, my server control has a combo box in it and a list box. As i change my selection in combobox, the items in listbox should change. So i wired up the selectedIndexChanges event.

I added the following line of code in CreateChildControls() method:

this.m_cbxSecurity.SelectedIndexChanged +=new EventHandler(m_cbxSecurity_SelectedIndexChanged);

and then i defined the method m_cbxSecurity_SelectedIndexChanged in the same class.

After doing all this, the control is not firing the event. Iam unable to guess wahts going on.
I'll appriciate some help.

Thanks

Is AutoPostBack set to true for the control?

Hey,

Did you try debugging the control? Are you sure it's not firing? Maybe it's the code within the event handler that has issues... try putting a breakpoint on that event handler to double-check.

There are two ways to approach this problem. The easy way is to create a event delegate for that combo box in the custom control, and then use the event delegate in the aspx page to response the event. The standard hard way is to implement IPostBackDataHandler to your custom server control (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemwebuiipostbackdatahandlerclasstopic.asp). This way you will be able to catch the postback from the request object and trigger your event handler. Hope this helps.
