Phillip,
Thanks for the response. I have made some progress after examing the
article under this link you provided:
http://msdn.microsoft.com/library/d...atingwebservercontroltemplatesdynamically.asp
then click on "Creating Templates Programmatically in the DataGrid
Control". I decided to use the DataGrid control.
and here's an excerpt from this article:
' Visual Basic
Private Sub Page_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load
Dim tc1 As New TemplateColumn()
tc1.HeaderTemplate = New _
DataGridTemplate(ListItemType.Header, "Column1")
tc1.ItemTemplate = New DataGridTemplate(ListItemType.Item, _
"Column1")
tc1.EditItemTemplate = New _
DataGridTemplate(ListItemType.EditItem, "Column1")
tc1.FooterTemplate = New _
DataGridTemplate(ListItemType.Footer, "Column1")
DataGrid1.Columns.Add(tc1)
Dim tc2 As New TemplateColumn()
tc2.HeaderTemplate = New _
DataGridTemplate(ListItemType.Header, "Column2")
tc2.ItemTemplate = New _
DataGridTemplate(ListItemType.Item, "Column2")
tc2.EditItemTemplate = New _
DataGridTemplate(ListItemType.EditItem, "Column2")
tc2.FooterTemplate = New _
DataGridTemplate(ListItemType.Footer, "Column2")
DataGrid1.Columns.Add(tc2)
SqlDataAdapter1.Fill(DsCategories1)
DataGrid1.DataBind()
End Sub
' Visual Basic
Private Class DataGridTemplate
Implements ITemplate
Dim templateType As ListItemType
Dim columnName As String
Sub New(ByVal type As ListItemType, ByVal ColName As String)
templateType = type
columnName = ColName
End Sub
Sub InstantiateIn(ByVal container As Control) _
Implements ITemplate.InstantiateIn
Dim lc As New Literal()
Select Case templateType
Case ListItemType.Header
lc.Text = "<B>" & columnName & "</B>"
container.Controls.Add(lc)
Case ListItemType.Item
lc.Text = "Item " & columnName
container.Controls.Add(lc)
Case ListItemType.EditItem
Dim tb As New TextBox()
tb.Text = ""
container.Controls.Add(tb)
Case ListItemType.Footer
lc.Text = "<I>Footer</I>"
container.Controls.Add(lc)
End Select
End Sub
End Class
My question is: why it produced four additional columns instead of two
since the code asked to dynamically allocate two
more columns in addition to the data columns coming back from the
database? This is what it looks like without my data
columns showing.
Column1 Column2 Column1 Column2
Item Column1 Item Column2 Item Column1 Item Column2
