Gridview selected Index Changed event problem

Hi,

 Are you bind the data to gridview at Page load or any events.

if you bind the data to gridview at the time of page loading. the data will be refreshed,wile you select the row..hence no data availble on gridview row selection.

If u bind the data to gridview at the time of page loaing use this one..

if(!Ispostback)

{

  //Bind data to gridview

}

Problem is nothing selected in DropDown hence SelectedItem is null.

Try something like this:

 protected void GridView1_SelectedIndexChanged(object sender, EventArgs e) {
            //Where index of Cells is the column in Grid that you wan't to refer
            string selectedRowValue = GridView1.SelectedRow.Cells[1].Text;
            DropDownList1.ClearSelection();

            //Here you'll have to make sure that value of the variable selectedRowValue exists in the DropDownLists list items or else you will end up getting an error
            DropDownList1.Items.FindByText(selectedRowValue).Selected = true;
            
        }
