C#代码

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

    {

        if (((DropDownList)e.Row.FindControl("DropDownList1")) != null)//判断有没有DropDownList

        {

            DropDownList ddl = (DropDownList)e.Row.FindControl("DropDownList1");

                  string lbl = ((Label)e.Row.FindControl("Label2")).Text;//获Label2的值

            ddl.Items.FindByText(lbl).Selected = true;//设置ddl的默认值

 

        }

    }
