您可以始终使用模板字段而不是命令字段。

<asp:TemplateField>
  <ItemTemplate>
    <asp:Button name="btnDelete" commandName="Delete" OnClientClick="return confirm('Delete 
this Item');" Text="Delete" runat="server" />
    <asp:Button name="btnEdit" commandName="Edit" Text="Edit" runat="server" />
  </ItemTemplate>
</asp:TemplateField>

完成此操作后,我将模板字段用于 ConfirmButtonExtender 来自Ajax控制工具包。

<asp:TemplateField>
   <ItemTemplate>   
       <asp:Button name="DeleteButton" commandName="Delete" Text="Delete" runat="server" />   
       <ajaxToolkit:ConfirmButtonExtender TargetControlId="DeleteButton" ConfirmText="Delete this entry?" />
   </ItemTemplate>   
</asp:TemplateField>  

这是一个用于删除确认的javascript。

 function not_check1()
            {
              var where_to1= confirm("Do you really want to delete this record??");

                                    if (where_to1 == true)
                                        {
                                            return true;
                                        }
                                    else
                                        {
                                            return false;
                                        }
           }

这是一个网格视图字段,从中调用javascript。

 <asp:TemplateColumn ItemStyle-Width="20" >
<ItemTemplate>
 <asp:ImageButton ID="ib_delete" runat="server" ImageUrl="~/image/images.jpg" commandName="Delete"  OnClientClick="return not_check1();" ImageAlign="Middle"/></ItemTemplate>

</asp:TemplateColumn>

在 RowDataBound 添加-

LinkButton objDelete = e.Row.Cells[0].Controls[0] as LinkButton;
objDelete.Attributes.Add("onclick", "javascript:return confirm('Do you want to delete this item?');");
