Thank you for writing.
Filtering the items or disabling some items does not depend on whether the RadListDataItem
has been added in the designer or at run-time.
Filtering can be set by using a predicate and its Filter
property or via a FilterExpression
, more information is available here: http://docs.telerik.com/devtools/winforms/dropdown,-listcontrol-and-checkeddropdownlist/dropdownlist/filtering.html
I am sending you attached an example project which I believe should get you going. In the sample, the items are filtered depending on the value of a RadToggleSwitch
control. I am also sending you a gif file showing the result on my end.
I hope this helps. Should you have further questions please do not hesitate to write back.
