Hello Telerik Team !
On a first hand, I have a form with postcode and city fields.
On a other hand, I have a database, with a table who carry an entire country of codepost/city accordingly.
I turn the postcode into a MultiColumn ComboBox, and the idea is when someone start filling at least 3 char of a post code, programmatically launch a request to the database to fill as both post code and city like :
the among query fill a DataTable "postcodeToCity" and I programmatically add the data like this :
My problem belongs in the right event to choose to launch the request, TextChanging do not exist, so I have been trying KeyDown, KeyPress & KeyUp without any success, indeed all char entered beyond the first char reset to the beginning. Even if I try to launch the request beyond a minimum length.
The postcode Multi Combo is in Suggest mode only.
So I am wandering if an Events could allow me to achieve this or if I simply try to achieve something impossible with this Control ?
Many thanks in advance if you have any idea or feedback for me !
