Hello,
I have a related RadComboBox demo like this link. It works fine.
However, I try to add Filter property for RadCombobox Country (Filter="Contains"), I have a problem.
I select an item of RadComboBox Continent then at first mouse click on RadComboBox Country, the item list of RadCombobox Country is shown as empty but the items count of RadComboBox Country > 0. I leave out of RadCombobox Country and then I click on RadCombobox Country again, the item list is shown as full.
Would be grateful for any ideas to show the item list of RadComboBox Country at first click. Thank you.
Sorry my English.
