這個問題，真是搞了我1天，這次記住他

第一種方法：

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{

GridViewRow drv = ((GridViewRow)(((Button)(e.CommandSource)).Parent.Parent));
Button btn1 = drv.FindControl("button3") as Button;
btn1.Text = "此訂單不可取消";
btn1.Enabled = false;

}

第二種方法：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{

//DataRowView drv = e.Row.DataItem as DataRowView;
//System.Web.UI.WebControls.Button btn1 = e.Row.FindControl("button3") as System.Web.UI.WebControls.Button;
//foreach (GridViewRow gvr in GridView1.Rows)
//{
// Button btn1 = GridView1.FindControl("button3") as Button;
// btn1.Text = "此訂單已經取消";
// btn1.Enabled = false;
//}

?

if (e.Row.RowType == DataControlRowType.DataRow)
{
if (e.Row.FindControl("Button3") != null)
{
Button btn1 = (Button)e.Row.FindControl("Button3");
btn1.Text = "此訂單已經取消";
btn1.Enabled = false;

}
}

}
