将过滤器行添加到gridview

Question

我想添加一行，其中将包含下拉列表、搜索文本框，也许还有其他控件以允许过滤到 gridview。我看过This Question，但对我没有帮助。如何添加一行以便将这些控件添加到我的 gridview？

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

Answer 1

这就是我所做的。

 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
