We use RadComboBox with On Demand service. Is it possible to enter text and select the first match on the server? Something like: Combo.SelectFirstMatchByText('...').

Or: how can we select an item on the server, when we have a unique value (the webservice would always return one or no item), without having all kinds of custom code with DataBind etc.

Hello,

There is no option to preselect an item from the web service. The possible approach is to select it on the client, once the items are populated.

Well, I think there should be an option. When converting a "normal" ComboBox to OnDemand behaviour, there is still code like "SelectedValue = xxx". Now there is not an easy solution to address this.

A possible solution would be: radComboBox.SelectFirstOrDefault("1234")

The code would call the specified method of the web service, and would pick the first item from the list returned. When I'm in the position, I will try to write something to address this point and post it here.

Hi,

Thank you for the feedback. In general the web service is not aware of the control and only returns JSON data which is then parsed on the client.
