添加篩選器行到gridview

Question

我想添加一行到那將包含下拉菜單，搜索文本框，也許其他控件允許篩選到gridview。我看過This Question，但它沒有幫助我。如何添加一行，以便將這些控件添加到我的GridView中？

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound 
Dim cell As New TableCell 
    Dim ddloper As New DropDownList 

    If e.Row.RowType = DataControlRowType.Header Then 
     Dim row As New GridViewRow(-1, -1, DataControlRowType.Header, DataControlRowState.Normal) 

     For Each c As DataControlField In CType(sender, GridView).Columns 
      Dim nc As New TableCell 
      nc.Text = c.AccessibleHeaderText 
      row.Cells.Add(nc) 
     Next 
     'e.Row.Parent.Controls.AddAt(-1, row) 

    End If 
end sub

這就是我所做的。

Protected Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound 
    Dim row As New GridViewRow(-1, -1, DataControlRowType.Header,DataControlRowState.Normal) 

    GridView1.Rows(2).Parent.Controls.AddAt(0, row) 



end sub
