然后将field设为TemplateField ，并将ID绑定到HiddenField中，并在删除时在该特定列上找到Control HiddenField.

谢谢

May it will help you
Make then field as a TemplateField and bind the ID in a HiddenField and while deleting find the Control HiddenField on that particular column.

Thanks

使用gridview的DataKeyNames属性.

use DataKeyNames property of gridview.

<asp:gridview id="gridview1" runat="server" datakeynames="Id">
<columns>
</columns>
</asp:gridview>

并在代码隐藏中使用它

and use it in codebehind

id = Convert.ToDateTime(gridview1.DataKeys[row.RowIndex].Values[0]);

尝试一下，使用templateFiled而不是boundfield并在其中保留一个hidednfield.

Try this, Use templateFiled instead of boundfield and keep a hidednfield inside it.

<asp:templatefield visible="false">
    <asp:hiddenfield id="hdnAttendanceID" runat="server" value='<%=Eval("AttendanceID"); %>'>
    </asp:hiddenfield>
</asp:templatefield>

然后在Row_Command事件的代码后面

And later in codebehind Row_Command event

GridViewRow gvr= (GridViewRow) e.CommandSource
HiddenField hdnAttendanceID= (HiddenField)gvr.FindControl("hdnAttendanceID");
string AttendanceID= hdnAttendanceID.Value;
