Empty value in XamComboEditor if value doesnt exists in ComboBoxItemsProvider
posted

 

Hi,

I need display empty value in xamdatagrid if saved value GUID doesnt exists in ComboBoxItemsProvider.

But I still see GUID value.

THX for help.

 

 foreach (DataRow dr in dt.Rows)

 {

                provider.Items.Add(new Infragistics.Windows.Editors.ComboBoxDataItem(new             Guid(dr["id"].ToString()), dr["name"].ToString()));

   }

 

Style s = new Style(typeof(Infragistics.Windows.Editors.XamComboEditor));

Setter set = new Setter(Infragistics.Windows.Editors.XamComboEditor.ItemsProviderProperty, provider);

 

 s.Setters.Add(set);

 field.Settings.EditorStyle = s;

    Hello,

     

    It has been a while since you have made your post, in case you still need support I will be glad to assist you further. I suppose the other community members can benefit from this answer as well. I have been looking through your post and I suggest you use the following code in your XamComboEditor’s EditModeEnding event:

      

    XamComboEditor combo = (sender as XamComboEditor);
if (combo.Value.ToString() != String.Empty)
{
    if (!(combo.ItemsProvider.ItemsSource as ObservableCollection<Guid>).Contains(Guid.Parse(combo.Value.ToString())))
    {
        combo.Value = String.Empty;
    }
}

     

    Feel free to write me if you have further questions.
