Populating the DropDown List !

Hi Friends,

I am creating one page in which I have 2 dropdown list boxes. I should populate the second Dropdown based on the text selected in the first dropdown box. So for this what is the technique I should use. please help me out in this.

Thank you,

DotNetMate.

Code Block

private void ListBox1_SelectedIndexChanged(object sender, System.EventArgs e)
{
string selectedItem = ListBox1.SelectedItem.Text;
//Populate ListBox2
}

You'd want to hook the SelectedIndexChanged event of ListBox1 and then populate ListBox2 based off of the SelectedItem of ListBox1. You need to make sure that AutoPostBack is set to true for ListBox1.
