Error when assigning a dataview to a gridview control

[WarrenW]

Hi Everyone,

I've been working on this error all day! I have a dataview created from a sqldatasource control and I'm trying to assign it to a gridview but I get Object reference not set to an instance of an object.

Code:

        Try
            Session("dsCustomer") = "Y"
            dsCustomer.SelectParameters("SEARCH1").DefaultValue = Trim(txtAccountNo.Text)
            Dim dv As DataView = DirectCast(dsCustomer.[Select](DataSourceSelectArguments.Empty), DataView)
            If dv.Count > 0 Then
                C1GridView4.DataSource = dv
                C1GridView4.DataBind()
                C1GridView4.Visible = True

Can't I assign a dataview as a datasource? Or not?

Thanks!
