RowDataBound可防止触发RowUpdating事件

Question

目前我正在使用未绑定的GridView，它有RowUpdating事件来编辑/更新数据到db。我还使用RowDataBound事件为所有列分组子标题。 但是我注意到，自添加RowDatabound以来，RowUpdating事件根本没有被触发。删除RowDataBound的那一刻，程序就像往常一样工作。

我需要使用一个主标题对Sub Headers进行分组。这个问题背后的原因是什么？ 我可以解决哪些解决方案，并根据要求实现目标。

     ///<summary>
     ///Adding sub headers to gridview
     ///</summary>
     ///<param name="sender"></param>
     ///<param name="e"></param>
    protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //columns
        GridViewRow outerGridView = e.Row;            

        if (outerGridView.RowType == DataControlRowType.Header)
        {
            GridViewRow gvrow = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Insert);

            TableCell cell0 = new TableCell();
            cell0.Text = "Project Details";
            cell0.HorizontalAlign = HorizontalAlign.Center;
            cell0.ColumnSpan = 6;

            TableCell cell1 = new TableCell();
            cell1.Text = "Monday";
            cell1.HorizontalAlign = HorizontalAlign.Center;
            cell1.ColumnSpan = 2;

            TableCell cell2 = new TableCell();
            cell2.Text = "Tuesday";
            cell2.HorizontalAlign = HorizontalAlign.Center;
            cell2.ColumnSpan = 2;

            TableCell cell3 = new TableCell();
            cell3.Text = "Wednesday";
            cell3.HorizontalAlign = HorizontalAlign.Center;
            cell3.ColumnSpan = 2;

            GridView2.Controls[0].Controls.AddAt(0, gvrow);
        }
    }
