Hi,

I have a problem when the dropdownlist editor is displayed in the cell. It always shows the first list item. When I move off to another cell the cell.value gets replaced by the list item.
I thought I can handle it in the Editor_SetControlValue by prepopulating the dropdown list with the cell.value. Following is my code:
*****************
Private Sub UnitEditor_SetControlValue(ByVal sender As Object, ByVal e As Infralution.Controls.VirtualTree.CellEditorSetValueEventArgs) Handles UnitEditor.SetControlValue
Dim dropDownList As Infralution.Controls.VirtualDropDownList = TryCast(e.Control, Infralution.Controls.VirtualDropDownList)
Dim UnitList As List(Of AttributeUnit) = TryCast(dropDownList.DataSource, List(Of AttributeUnit))
_unitSearchValue = New AttributeUnit("", e.Value.ToString)
Dim FoundUnit As AttributeUnit = UnitList.Find(AddressOf FindUnitListItem)

UnitDropDownList.SelectedItem = FoundUnit
End Sub


Private Function FindUnitListItem(ByVal value As AttributeUnit) As Boolean
If _unitSearchValue.Description = value.Description Then
Return True
Else
Return False
End If
End Function

********************

However, changing the dropdowlist.selecteditem doesn't change the text displayed.


Please help!!!

Thanks in advance

If you bound the Unit column to the Unit object (not to the Unit.Description) object then you should just be able to set the CellEditor for the column and it will all work automatically. For a VirtualDropDownList you have to set the CellEditor.ValueProperty to "SelectedItem".

You should, however, also be able to do it the way you are attempting. Did you paste this code from your project? Because that would probably explain why it's not working. The line:
