Filter for any of multiple words?

[Mike Trank]

Hi.  Would it be possible to modify the "contains" filtering behavior to find any of multiple words in the combobox data?

For example: a combobox item is "follow the yellow brick road".  As I type 'the' then a space and then 'road' it would find this item because it contains any of my filtering words.  The current 'contains' behavior would not have found this item as it would have been looking for 'the road' as one string/keyword.  I hope I am making sense.

Can the client-side events such as itemrequesting or something similar be used to intercept/modify the filter before sent to the data source?

Thank you very much.

Hi Mike,

The desired functionality is not supported our of the box from the RadComboBox, but could be achieve if the filtering is manually performed. If the control is bound to a web service, the developer could query the data set in the desired way. If the web service approach is not applicable, the server ItemsRequested event could be used instead.

All the best,

And how can we achieve that? Is there an analytic example with code? Thnx

Any news Mr Dimitar? Is it possible for you to display an example of a web service and one for itemsrequested? I would appreciate that, thnx :)

Hi zznbilly,

As this scenario is not supported out of the box, we do not have examples for it. As Dimitart mentioned, you can use the built-in APIs to send custom requests to the server where you can access and parse the context and filter the database accordingly.

Here are the instructions to load items from the WebService:

• Loading Items from a Web Service
• Loading Items from WCF Service

The following article explains how to send custom context to the server:
