Hi, bind your dropdown using below process:

C#

if(!isPostback)
{
BindDDL();
}

and write a function to bind ddl.

Don't forget to mark, if it is your solution. :-)

Hi,
set the AutoPostBack property of DropDownList to false,

and in the page loading state you can handle the post back by this

C#

if(!this.Page.IsPostBack)
{
   // do ...
}

good luck
