.radGridView1.MasterGridViewTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

But the problem with that is it automatically sizes the columns to be all equal which is not suitable for this application. And in this case giving each column a fixed length is also not an option as this application needs to run on several resolutions. When i tried using 

 this.radGridView1.MasterGridViewTemplate.BestFitColumns(); 

The columns only appear on part of the child form(ie if the user resizes the child form, the columns do not resize with it). So if you could please let me know if there is a workaround. Thanks in advance.

.PhoneTypeBindingSource.DataSource = CMXApplication.LookUps.PhoneTypes

CType(Me.PhonesRadGridView.Columns("PhoneType"), Telerik.WinControls.UI.GridViewLookUpColumn).DataSource = Me.PhoneTypeBindingSource.DataSource

Because of the nature of the custom objects I intercept the Cellformatting event, to display the name of the phone type

Private Sub PhonesRadGridView_CellFormatting(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.CellFormattingEventArgs) Handles PhonesRadGridView.CellFormatting

If e.CellElement.RowIndex >= 0 Then

If e.CellElement.ColumnIndex = 1 Then

e.CellElement.Text =

CType(PhonesBindingSource(e.CellElement.RowIndex), FTS.CMX.CMXModel.Phone).PhoneType.Name

End If

End If

End Sub

so far so good. When I edit the grid row I select a different phonetype in my GridViewLookUpColumn (PhoneType). I need to assign  a phonetype from the  GridViewLookUpColumn  to my phone. What I think I need to do is this, capture the CellEndEdit value from the GridViewLookUpColumn and assign a phonetype to my phone.

When I query the GridViewLookUpColumn  it is not the selected value from my grid

Can you give me pointers on how to achieve the desired results?

Private Sub PhonesRadGridView_CellEndEdit(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles PhonesRadGridView.CellEndEdit

Dim Phone As FTS.CMX.CMXModel.Phone = ContactProxy.Contact.Phones(PhonesRadGridView.CurrentRow.ViewInfo.CurrentIndex)

If PhonesRadGridView.CurrentRow.Cells(0).Value = String.Empty Then

If Phone.EntityState = EntityState.Added Then

PhonesRadGridView.Rows.RemoveAt(ContactProxy.Contact.Phones.Count - 1)

ContactProxy.Contact.Phones.Remove(Phone)

End If

Else

If e.ColumnIndex = 1 Then 'assign the phone type to the phone

'CType(Me.PhonesRadGridView.CurrentCell, Telerik.WinControls.UI.GridComboBoxCellElement).Text

Debug.WriteLine(

CType(Me.PhonesRadGridView.CurrentCell, Telerik.WinControls.UI.GridComboBoxCellElement).Value)

End If

End If

End Sub

Thanks P
