I try to dynamically add datagrid to my web form in VB.NET. But when I

try to setup the datasource, the DATASOURCE is not the property of
datagrid. Anybody know the reason? Here is my code:

Public Sub CreateGrid()
'declare a new datagrid and set properties
   Dim DataGrid1 As New DataGrid()
     DataGrid1.ShowHeader = True
   DataGrid1.AutoGenerateColumns = False
   DataGrid1.SelectedItemStyle.BackColor = Color.Yellow

   'add bound columns to the datagrid
   Dim datagridcol As New BoundColumn()
   datagridcol.HeaderText = "Last Name"
   datagridcol.DataField = "lastname"
   DataGrid1.Columns.Add(datagridcol)

   datagridcol = New BoundColumn()
   datagridcol.HeaderText = "First Name"
   datagridcol.DataField = "firstname"
   DataGrid1.Columns.Add(datagridcol)

   'bind datagrid
   '*************************************
   'I will get error in here and tell me that
   'datasource is not the property of DataGrid1
   DataGrid1.DataSource = GetDataSet()
   DataGrid1.DataBind()

   'add datagrid to the page
   Page.Controls(1).Controls.Add(DataGrid1)

End Sub

I tried the same thing in C#, the DATASOURCE is the property of
datagrid and it works great.

thanks for any help

I found that I have another class also called datagrid which caused
that there is no datasource property. I should use the full name like
system.web.ui.controls.datagrid to declare it.

I'm glad you finally figure it out yourself.
