RadDataBoundListBox and DataTemplate

[Peter]

Hi,

how is it possible, that I can hide empty rows from my listbox? Now I use a RadDataBoundListBox with a Data Template.

Thanks in advanced for your help.

Hello Peter,

Thank you for contacting us.

There are three scenarios with empty items:

• The property specified by DisplayMemberPath is null: in this case the null items will not be visualized by default.
• The ItemsSource contains null elements and DisplayMemberPath is not specified: the same as the previous scenario.
• The ItemsSource collection contains null elements and DisplayMemberPath is specified: in this case you will have to edit the template of the items in order to avoid NullReferenceException when the DisplayMemberPath property is not found.

Support for empty items without editing the ItemTemplate seems useful and I have logged it in our ideas & feedback portal where our community can vote for it an raise its priority.

I hope this helps. Please, let us know if you have further questions.

Regards,
