Using multiple dropdownlist in gridview control

I have tried that but it did not work for me. Actually what i am trying to do is. I am not binding the gridview to any source but i need to have dropdownlist (4) with data from sql table. Should i use empty data template to display the gridview but the gridview should have dropdownlists populated from database. No other datt is there in gridview except for the dropdownlists which are populated.. Please give me some idea where am i going wrong?

You will have to bind the Dropdown in EmptyDataTemplate in the following way

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)     
{         
    if (e.Row.RowType == DataControlRowType.EmptyDataRow)         
    {             
           DropDownList ddl = (DropDownList)e.Row.FindControl("ddl1");
           //Bind here

    }              
}

Ok i will try this one and let u know

Hi Mudassar Thanks it worked.

How do i write selectionIndex changed for these dropdownlists?

Should all dropdownlists have autopostback to true in such case for selection?

Yes for all dropdowns set AutoPostBack = true and set the SelectedIndexChanged event

Note: Make sure you bind Grid only in !IsPostBack condition otherwise your events will never hit.
