如何將hovermenuextender控件綁定到動態表格視圖中具有多列的行？

Question

我希望將hovermenu彈出窗口附加到從數據源動態填充的gridview的行中。 我試圖在發生rowdatabound事件時將hovermenuextender控件的TargetcontrolId屬性設置為行唯一ID。 但是，彈出窗口不是出現在每一行的右側，而是出現在標題行的右側。 有人可以幫我解決這個問題嗎？ 我在下面的代碼中使用了相同的代碼

代碼背后：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    try
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            HoverMenuExtender hoverMenu =(HoverMenuExtender)e.Row.FindControl("hme2");
            if (hoverMenu != null)
            {
                hoverMenu.TargetControlID = hoverMenu.Parent.Parent.UniqueID;

            } 
        }
    }
}

Answer 1

protected void gv_RowCreated(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        AjaxControlToolkit.HoverMenuExtender ajxhovermenu = (AjaxControlToolkit.HoverMenuExtender)e.Row.FindControl("ahm_1");
        e.Row.ID = e.Row.RowIndex.ToString();
        ajxhovermenu.TargetControlID = e.Row.ID;
    }
}

在GridView的RowCreated事件中提供HoverMenuExtender的TargetControlID並將其設置為RowID
