Hi.

I am using a radrotator for an image gallery. When i first bind the rotator it is fine.

But when i bind it again after postback, it gives me an error:

Unable to cast object of type 'Telerik.Web.UI.RadRotatorItem' to type 'Telerik.Web.UI.ControlItem'.

I don't understand why it is doing that.

Here is the code for the binding:

Private Sub RebindRotator()
        Dim projID As Integer = CInt(Request.QueryString("ID"))
        Dim query = From tbl In db.ProjectsImages Where tbl.ProjectID = projID Select tbl

        If Not query Is Nothing Then
            ThumbnailsRadRotator.DataSource = query
            ThumbnailsRadRotator.DataBind()
        End If
    End Sub

Any help would be highly appreciated :-(
