I have custom objects of type phone and each phone has a phonetype example Phone.PhoneType.Name="Business"
I have a grid which is bound to a generic list of Phone. One of the columns in the grid is a GridViewLookupColumn named phonetype (ie. Business, Mobile, Fax etc..)
On the init of my app I assign the PhoneTypes to the data source
Me
.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

Thank you for contacting us.
Please see the sample code below:
| Dim t As New DataTable() |
| t.Columns.Add("some column", GetType(String)) |
| t.Columns.Add("phone column", GetType(String)) |
| t.Rows.Add("some text", "Mobile") |
| t.Rows.Add("some text", "Business") |
| t.Rows.Add("some text", "Business") |
| t.Rows.Add("some text", "Fax") |
| Me.radGridView1.MasterGridViewTemplate.AutoGenerateColumns = False |
| radGridView1.Columns.Add(New GridViewTextBoxColumn("some column")) |
| Dim c As New GridViewLookUpColumn("phone column") |
| c.DataSource = New String() {"Mobile", "Business", "Fax"} |
| c.FieldName = "phone column" |
| radGridView1.Columns.Add(c) |
| Me.radGridView1.DataSource = t |
| Me.radGridView1.MasterGridViewTemplate.EnableFiltering = True |
This example will soon become available in our documentation. When you edit the values in the comboboxes they are saved in your database (the t DataSet in the case above).
Do not hesitate to write me back if you have more questions.

Thanks for getting back to me, I have another thread running where I am having trouble with grids generally. I think it is because the grid is bound to custom objects in a generic list . I am investingating at the moment and I will get back to you with my findings

Thank you. Please make sure that you access the RadGridView only from the thread where it was created.
