AttendanceID colunm隐藏但该ID需要Delete.但是我找不到此ID.请提供适当的解决方案.


AttendanceID colunm Hide but This id need for Delete.But i cant find this ID. Pls give appropriate solution.

推荐答案


<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]);


<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;
