在datagridview标头单元上自动过滤 [英] autofilter on datagridview headercell

问题描述

我想在Windows的datagridview控件的标题单元格中显示自动筛选"下拉按钮.
这就是我所拥有的:

I would like to display the AutoFilter drop-down button in a header cell of the windows''s datagridview control.
This is what I have:

DataTable dt = new DataTable();
            dt = DataGet();

            if (dt.Rows.Count > 0)
            {
                DataView defaultView = dt.DefaultView;

                dgv.DataSource = null;
                dgv.DataSource = defaultView;
            }


dgv.Columns["Surnames"].HeaderCell = new DataGridViewAutoFilterColumnHeaderCell();

上面的这一行给出了以下错误.
你知道如何解决吗?

请注意，我不想在设计时创建datagridview的字段，因为正如您在这段代码中所看到的，它们会自动添加到datagridview中.

谢谢


{包含的DataGridView控件的DataSource属性必须设置为BindingSource."} System.Exception

This above line gives the following error.
Do you know how this can be solved please?

Note that I do not want to create the fields of the datagridview at design time because as you see in this code, they get added automatically to the datagridview.

Thanks
