Question

我正在使用我的格式的数据网格，它有2个按钮，编辑和删除，但这些事件并没有被触发。我在代码中哪里出错了。我在vb.net中运行相同的代码，但在c＃中转换后，它无效。 Plz帮助。

在将代码从vb.net转换为c＃时，我是否还需要进行其他更改？提前谢谢！

在您的aspx文件中，您无法调用“dgjob_ItemCommand”方法，因为您希望事件被触发。

你必须在Grid的OnSelectedIndexChanged事件上调用“dgjob_ItemCommand”。

<asp:datagrid id="dgjob" runat="server" CssClass="davpdgdatagrid" 
                    PageSize="100" AutoGenerateColumns="False" ShowFooter="True" 
                    BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" 
                    BorderWidth="1px" CellPadding="4" ForeColor="Black" GridLines="Horizontal" 
                    HorizontalAlign="Center" OnSelectedIndexChanged="dgjob_ItemCommand">
                        <AlternatingItemStyle CssClass="davpdgalt"></AlternatingItemStyle>

我希望这会有所帮助。

datagrid_itemcommand事件未被触发
