Anyone have any ideas on why the code below will show up
in a browser's sourcecode as an empty table, and is not
visible?

aspx:
<headertemplate>

<asp:Table ID="MyTable" runat="server" />

</headertemplate>

codebehind:
Class MyClass....

Protected WithEvents CaseTypeHeaderTable As
System.Web.UI.WebControls.Table = New
System.Web.UI.WebControls.Table
Protected WithEvents CaseTypeSortButton As
System.Web.UI.WebControls.Button = New
System.Web.UI.WebControls.Button
Protected WithEvents CaseTypeFilterDropDown As
System.Web.UI.WebControls.DropDownList = New
System.Web.UI.WebControls.DropDownList
Protected WithEvents CaseTypeHRow1 As
System.Web.UI.WebControls.TableRow = New
System.Web.UI.WebControls.TableRow
Protected WithEvents CaseTypeHRow2 As
System.Web.UI.WebControls.TableRow = New
System.Web.UI.WebControls.TableRow
Protected WithEvents CaseTypeHCell1 As
System.Web.UI.WebControls.TableCell = New
System.Web.UI.WebControls.TableCell
Protected WithEvents CaseTypeHCell2 As
System.Web.UI.WebControls.TableCell = New
System.Web.UI.WebControls.TableCell


private sub Page_Load.....
call setMyTable()
end sub

Private Sub setMyTable()
With Me.MySortButton
.BackColor = Color.Maroon
.ForeColor = Color.White
.ID = "MySortButton"
.Text = "Sort This Column"
.ToolTip = "Click to sort this column"
.EnableViewState = True
End With

With Me.MyFilterBox
.ID = "MyFilterBox"
.ToolTip = "Enter value on which to filter records
and press [ENTER]. To show all records clear the box and
press [ENTER]."
.EnableViewState = True
End With

With Me.MyCell1
.VerticalAlign = VerticalAlign.Bottom
.HorizontalAlign = HorizontalAlign.Center
.Controls.Add(Me.MySortButton)
End With

With Me.MyCell2
.HorizontalAlign = HorizontalAlign.Center
.VerticalAlign = VerticalAlign.Top
.Controls.Add(Me.MyFilterBox)
End With

With Me.MyRow1
.Cells.Add(Me.MyCell1)
End With

With Me.MyRow2
.Cells.Add(Me.MyCell2)
End With

With Me.MyTable
.Rows.Add(Me.MyRow1)
.Rows.Add(Me.MyRow2)
End With
End Sub
End Class

Hi Sue,

After reviewing the description, I think the question is: You want to add
several controls to a table, and then add the table to the headertemplate
of a control (DataGrid / DataList/ Repeater). However, now the able is
showed empty in the browser. Please post here if I have any
misunderstandings.

I remembered that I have answered this issue before. Did it not work? You
may want to send me an email (remove "online") attached your simplified
source code (.vb and .aspx) then I might be able to work out what the
problem is.

Here are some suggestions:

If the table is in a header template, we need use FindControl method to get
the correct reference to it.

For example, the table is in the headertemplate of a datagrid:

Dim TestTable As Table

Private Sub DataGrid1_ItemDataBound(ByVal sender As System.Object, ByVal e
As System.Web.UI.WebControls.DataGridItemEventArgs) Handles
DataGrid1.ItemDataBound
If e.Item.ItemType = ListItemType.Header Then
Dim ctrl As Control = e.Item.FindControl("MyTable")
If Not ctrl Is Nothing Then
TestTable = CType(ctrl, Table)
End If
End If
End Sub

Then we can add rows to TestTable.

Best regards,
Lewis
