Question

在RadGrid上我可以使用CommandItemTemplate来定义我自己的按钮，在我的例子中，保存并取消编辑（如下所示）

＆＃13;

<CommandItemTemplate>
    <div style="padding: 5px 5px;">
        <asp:LinkButton ID="btnUpdateEdited" runat="server" CommandName="UpdateEdited">Update</asp:LinkButton>
        <asp:LinkButton ID="btnCancel" runat="server" CommandName="CancelAll">Cancel editing</asp:LinkButton>
    </div>
</CommandItemTemplate>

＆＃13;

在后面的代码中，我设置了ItemCommand。

> protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
    if (e.CommandName.CompareTo("UpdateEdited") == 0)
    {
        var commandItem = ((GridCommandItem)e.Item);
        //Updade code here.
    }
}

如何使用修改后的字段访问修改后的行，以便执行更新？

Answer 1

你应该在命令项中拥有它们，你可以像这样访问它们：

GridDataItem item = (GridDataItem)e.Item;
string value = item["ColumnUniqueName"].Text;

Answer 2

这是你想要的吗？只是您可能需要修改它的示例..
