GridView中的RowCommand问题

Question

在网格视图中第一次单击行项时出现了这个奇怪的问题，因为它不会触发。我正在将一个用户控件动态加载到占位符中。在第一次单击失败后，后续的单击都是正常的，并触发RowCommand事件。

非常感谢您的任何建议

    protected void Page_Load(object sender, EventArgs e)
    {
        this.PreRender += new EventHandler(Group_PreRender);
        this.Init +=new EventHandler(Group_Init);
        AttachEvents();

        if (Page.IsPostBack)
        {
            GetData();

        }
        else
        {
            gvName.DataBind();
        }

    }


    private void AttachEvents()
    {
        gvName.RowCommand += new GridViewCommandEventHandler(gvName_RowCommand);
    }
    protected void gvName_RowCommand(object sender, GridViewCommandEventArgs e)
    {
             //code here
    }

我还尝试在标记中添加事件

​

       <asp:Button ID="btnDisable" runat="server" CommandArgument="<% # Container.DataItemIndex %>" Visible="<%# ((EducateMe.BaseTypes.AbstractLink)Container.DataItem).IsActive == true %>" CommandName="Disable" ToolTip="Disable" Text="Apply" />
