Reference a Textbox in a dynamically created header row in a gridview

[joss Perold]

Hi

I have a gridview that onRowCreated adds a second header row above the first one. In the created one there is a textbox control. My question is how would I access that textbox in the code behind?


The code for the created row is below:

 
            If e.Row.RowType = DataControlRowType.Header Then
                Dim gvHeaderGrid As GridView = sender
                Dim gvrHeaderGridview As New GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Insert)
                Dim txtExpectedBlackSwanDate As New TextBox
                txtExpectedBlackSwanDate.Columns = 3
                txtExpectedBlackSwanDate.CssClass = "input"
                Dim lblExpectedBlackSwanDate As New Label
                lblExpectedBlackSwanDate.Text = "Black Swan Expected Date:"
 
                For colAdd = 0 To 2
                    Dim tblCellAdd As New TableCell
                    If colAdd = 0 Then
                        tblCellAdd.Controls.Add(lblExpectedBlackSwanDate)
                        tblCellAdd.Controls.Add(txtExpectedBlackSwanDate)
                    ElseIf colAdd = 1 Then
                        tblCellAdd.Text = "Black Swan Cycle"
                    ElseIf gvBlackSwanDeflation.AutoGenerateColumns = True And colAdd = 2 Then
                        tblCellAdd.Text = "Black Swan Deflation Rates per Annum"
                    End If
 
                    If colAdd < 1 Then
                        tblCellAdd.ColumnSpan = 1
                    ElseIf colAdd = 1 Then
                        tblCellAdd.ColumnSpan = 2
                    ElseIf gvBlackSwanDeflation.AutoGenerateColumns = True And colAdd = 2 Then
                        tblCellAdd.ColumnSpan = 6
                    Else
                        tblCellAdd.ColumnSpan = 3
                    End If
                    tblCellAdd.HorizontalAlign = HorizontalAlign.Center
                    gvrHeaderGridview.Cells.Add(tblCellAdd)
                Next
 
                CType(gvBlackSwanDeflation.Controls(0), Table).Rows.AddAt(0, gvrHeaderGridview)
 
            End If
        Catch ex As Exception
 
        End Try
    End Sub
 

Any help would be most appreciated. Thanks in advance
