[Solved] vb.net radgrid tutorial not working

[jtby]

 

I am trying out radgrid silverlight control.  From Help I choose Controls->RadGridView->Tutorial->Getting Started, and copy and paste the code there into my project.  However code fails at the highlighted line below with Too many arguments to 'Public Sub New()'

Private Function GetObservableObjectData() As ObservableCollection(Of Customer)

 

 

    Return New ObservableCollection(Of Customer)(GetData())

 

 

End Function

... is it a problem in the documentation?  I have copied the code exactly.

Hello jtby,

Thank you for pointing this out. Indeed, there is a mistake in the documentation, which we will correct right away. The error is due to the fact that in Silverlight the ObservableCollection(Of T) class does not have a constructor accepting an IEnumerable(Of T). We will correct the code snippet so it works in both Silverlight and WPF.

The correct code you should use is:

    Private Function GetObservableObjectData() As ObservableCollection(Of Customer)
        Dim data As New ObservableCollection(Of Customer)()
        For Each customer As Customer In data
            data.Add(customer)
        Next
        Return data
    End Function

I hope this helps. Please, excuse us for the inconvenience.

Kind regards,
Ross
