Hello everybody,
we are using RadControls for WinForms Q3 2009 SP1 and want to change the items of a ComboboxColumns editor by the value of the cell of another column.
For this in GridView.CellBeginEdit we set the editors element to the filtered datasource and expected the Comboxbox just to show the items of the filtered datasource BUT it shows all items of the original unfiltered datasource.
RadComboBoxEditor editor = m_gridView.ActiveEditor as RadComboBoxEditor;
if (null != editor)
{
((RadComboBoxElement)(editor.EditorElement)).DataSource = filteredDataSource;
}
Did we make a mistake or is it just a bug???

Hi DGPunkt,
Thank you for the question.
The CellBeginEdit event is fired before the moment the DataSource of the GridViewComboBoxColumn is assigned to the RadComboBoxEditor. Therefore, your setting is overridden by the default DataSource of the GridViewComboBoxColumn.
In order to assign a custom DataSource to the RadComboBoxEditor, you should use the CellEditorInitialized event, because it is fired after the default RadComboBoxEditor initializations take place.
I am attaching a sample project which demonstrates the approach. I hope that it will help you in your further development.
