我希望将悬停菜单弹出到从数据源动态填充的网格视图的行。我尝试在发生 rowdatabound 事件时将 hovermenuextender 控件的 TargetcontrolId 属性设置为行唯一 ID。但是弹出窗口不是出现在每一行的右侧，而是出现在标题行的右侧。有人可以帮我解决这个问题吗？我使用下面的代码相同

代码隐藏：

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;

            } 
        }
    }
}

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;
    }
}

Give TargetControlID of the HoverMenuExtender in RowCreated event of GridView and set it as the RowID
