How to clear / delete value from ComboBoxItemsProvider
posted

I am trying to work out a way to delete / clear / set null a cell once it has had a value selected by the combo box selector.

Is there any built in behaviors that will let me do this. Currently once I have something selected it is impossible to set it back to empty

 

thanks for your suggestions

regards

Murray

    Hello Murray,

    You can handle SelectedItemChanged event of XamComboEditor, then retrieve the active record, and use CellValuePresenter object for a given cell and set it like this:

    privatevoid xamCombo1_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e)

    {

     

     

    DataRecord dr = xamDataGrid1.ActiveRecord as DataRecord;

     

    if (dr != null) CellValuePresenter cell = CellValuePresenter.FromCell(dr.Cells["your cell"

     

    {

     

    ]);

    cell.IsEnabled =

     

    false; 

     

    // Or

     

    cell.Visibility =

     

    Visibility.Hidden;

      }

    }
