Dear all:


how could i avoid a  selectionchanged event when i bind data source to a combobox?
ex:
void getVersionCompleted(...)
{
....
combobox1.ItemsSource = e.result;
//then it will call combobox1.selectionchanged event but i don't want
}

i try add combobox1.items.clear() before "combobox1.ItemsSource = e.result;"
but got a error message: System.InvalidOperationException was unhandled by user code
please kindly help...

thanks~

Hello Judy,

If RadComboBox has set the SelectedValue property before you set ItemsSource it will try to select the item with the specified value. If you don't have set SelectedValue you should not get SelectionChanged event.

In other words the SelectionChanged event is raised every time one of the SelectedValue or SelectedItem properties change.
