Question

我想在删除行之前询问删除按钮是否要求确认。我该怎么做呢？

<dx:GridViewCommandColumn VisibleIndex="3" ButtonType="Image" Width="10px">
    <DeleteButton Visible="True" Text="<%$ Resources:GlobalResource, Delete %>" >
        <Image   Url="../Resources/Imgs/Erase.gif" ToolTip="<%$ Resources:GlobalResource, Delete %>" />
    </DeleteButton>
    <HeaderCaptionTemplate>
        <dx:ASPxButton runat="server" ID="ButtonAddNew" Text="<%$ Resources:GlobalResource, Add %>" ToolTip="<%$ Resources:GlobalResource, Add %>" Image-Url="~/Resources/Imgs/Add.gif" AutoPostBack="False">
            <ClientSideEvents Click="function(s, e) { OperationsGrid.AddNewRow(); }" />
        </dx:ASPxButton>
    </HeaderCaptionTemplate>
</dx:GridViewCommandColumn>

假设我已经正确理解了你的问题（你想在执行删除之前得到确认消息，对吗？），我已经使用了OnClientClick按钮属性，如下所示：

  <asp:ImageButton ID="btnDel" runat="server" ImageUrl="Images/delete-button.jpg" ToolTip="Delete" OnClientClick ="return confirm('Are you sure to delete this record?');"/>

另外，在后面的代码中，为了检查确认框中的哪个按钮被按下（确定/取消），我有以下代码：

    if (btnDel.CausesValidation == true)    //ok was pressed.
       {
             //perform delete.
       }

稍后编辑：

<dx:ASPxGridView ID="myGrid" runat="server" AutoGenerateColumns="False" ClientInstanceName="GridView1" >
    <ClientSideEvents CustomButtonClick="function(s, e) {     
              e.processOnServer = confirm('Do you really want to apply changes?'); }" />        
</dx:ASPxGridView>
