asp.net - 如何为 Commandfield ButtonType 添加工具提示作为图像

Question

我必须为我的 gridview 编辑图像按钮添加工具提示。我编码为 Commandfield。

<asp:CommandField ButtonType="Image"  
    HeaderStyle-HorizontalAlign="center"
    EditText="Edit" UpdateText="Edit" 
    ShowEditButton="True"  
    ItemStyle-VerticalAlign="Top"
    EditImageUrl="~/Images/edit.png"    
    UpdateImageUrl ="~/Images/Save.png" CancelImageUrl ="~/Images/cancel.png" 
    ItemStyle-Width="15px" ControlStyle-Width="15px">
</asp:CommandField>

是否可以在 gridview 命令字段按钮类型中添加工具提示作为图像？

以下代码效果很好:

protected void gvResourceEditor_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            try
            {
                if (e.Row.RowType == DataControlRowType.DataRow)
                {
                    e.Row.Cells[4].ToolTip = "Edit Resource Details";
                    if (e.Row.RowState == DataControlRowState.Edit || e.Row.RowState.ToString() == "Alternate, Edit")
                    {
                        int i = 0;
                        foreach (TableCell cell in e.Row.Cells)
                        {
                            if (e.Row.Cells.GetCellIndex(cell) == 4)
                            {
                                ((System.Web.UI.WebControls.ImageButton)(e.Row.Cells[4].Controls[0])).ToolTip = "Update Resource Details";
                                ((System.Web.UI.LiteralControl)(e.Row.Cells[4].Controls[1])).Text = " ";
                                ((System.Web.UI.WebControls.ImageButton)(e.Row.Cells[4].Controls[2])).ToolTip = "Close Resource Details";
                            }
                            i++;
                        }
                    }
                }
            }
            catch (Exception _e)
            {
            }
        }
