Why my ListBox Control in my Web Control is not Raising the SelectedIndexChanged Even

Hi All,
I am creating a control with ASP "ListBox" control.
Also I have added necessary code to handle the ListBox.SelectedItemChanged
Event.
But surprisingly the control is not comng to this code at all.
Why my ListBox Control in my Web Control is not Raising the
SelectedIndexChanged Event ?
Any suggestions please?
Thanks
Anand Ganeshdid you set the AutoPostBack property to true?
<asp:listbox ... AutoPostBack="True" />

Yes I did. Here is the code.
protected override void CreateChildControls()
{
foreach(string st in this.GlobalArrayList)
{
TheListBox.Items.Add(st) ;
}
TheListBox.Attributes.Add("AutoPostBack","True") ;
TheListBox.Attributes.Add("id","ListBoxCheck") ;
TheListBox.Attributes.Add("runat","server") ;
TheListBox.Attributes.Add("OnSelectedIndexChanged","TheListBox_SelectedIndex
Changed")
;
this.Controls.Add(TheListBox) ;
Button TheButton = new Button() ;
TheButton.Click +=new EventHandler(TheButton_Click);
this.Controls.Add(TheButton) ;
//base.CreateChildControls ();
}
But still the TheListBox_SelectedIndexChanged function is not being called.
I am using the CreateChildControls() function to create my controls and I am
not overiding and using the render function.
Will this cause an issue?
Thank
Anand

Hi,
The 'attributes' collection you are adding to, is for client-side
attributes only. Instead, use the appropriate property of the ListBox
control like this:
TheListBox.AutoPostBack = true;
TheListBox.ID = "ListBoxCheck";
TheListBox.SelectedIndexChanged += new
EventHandler(TheListBox_SelectedIndexCha
nged);

Thanks a lot Roger it Worked.
