Hi,
for my previous post i got the result, now in the ddl i m inserting the values using property window in design mode and during execution during selectedindex change event,ddl is not retaing the value i have written the code as below:
protected void ddlFil_SelectedIndexChanged(object sender, EventArgs e)
{
if (Convert.ToInt32(ddlFil.SelectedItem.value)== 1)
{
Response.Redirect("pAssUsr.aspx");
}
}
In the above code eventhough the selected value is 1 i m seeing 0 during debuging this is becoz after post back the value is not retained in the ddl... how to make the ddl to retain the value...
