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?


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


thanks for your help

Hi Donna:

DataSource is a property available on a DataGrid for all the
languages. Are you saying DataSource doesn't appear in the properties
window? Or doesn't compile?

Actually datasource is not the property of datagrid when you create the
datagrid in the run time instead of design time. Here is the code
Public Sub CreateGrid()
'declare a new datagrid and set properties
Dim DataGrid1 As New DataGrid()

'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

Any thought?
thanks

That seems odd, the only thing I can think of is that you have another
class by the name of DataGrid. Try:

Dim DataGrid1 As New System.Web.UI.WebControls.DataGrid

Any luck?

Scott,
Thank you very much. I thought that I import the
System.Web.UI.WebControls, then I could use datagrid directly. You
are right that there should be another class called datagrid somewhere
which I even did not know it exists. Thanks again
