DataGrid 增加一列全选

JS:

 function SelectAll(tempControl) { //将除头模板中的其它所有的CheckBox取反 var dt = document.all.<%=dgdFileList.ClientID%>; for(var i = 1; i < dt.rows.length; i++) { var checkb = dt.rows(i).cells(0).childNodes(0); if(tempControl.checked) checkb.checked= true; else checkb.checked= false; } }

DataGrid:

  <asp:TemplateColumn HeaderStyle-Width="10px">
            <HeaderTemplate>
             <asp:CheckBox id="chkHeader" runat="server" AutoPostBack="False" onclick="javascript:SelectAll(this);"></asp:CheckBox>
            </HeaderTemplate>
            <ItemTemplate>
             <asp:CheckBox id="chkItem" runat="server"></asp:CheckBox>
            </ItemTemplate>
           </asp:TemplateColumn>
