Try below code inside the
SelectedIndexChanging
Event.
GridViewRow row = GridView1.Rows[e.NewSelectedIndex];
DropDownList ddl = row.FindControl("ddlDropDownList") as DropDownList;
someLabel.Text = ddl.SelectedValue.ToString();
OP 's reply
Nope. It doesn't work, but I figured out the solution. It is:
Label drpValue = (Label)this.GridView1.Rows[e.NewSelectedIndex].Cells[1].FindControl("Label1");
Lbl1.Text = drpValue.Text;
