Duplicate entry in DDL

Hi,

Use IsPostBack on page_load bcoz it fires only once when page is loaded first time.

page_load
{
if(!IsPostBack)
{
       
}

}

Hi RIM Singh,

Put a check if it's a postback on page load. Wrap your Page_Load codes inside an if block like this:
----------------------------------------

if(!IsPostBack)
{
        //fill the ddl
        // other codes go here if required
}

-----------------------------------------


Happy Coding :)

before binding data to dropdown make it clear 1st

Ex:
 ddlCountry.Items.Clear();;

after that write the dropdown bind code
put your bind code within

if(!IsPostBack)
{
      
}

if any problem rply.
