Hello JT,

The MultiColumnComboBox can be bound the ClientDataSource. The settings to configure the WebService binding are almost identical between the MultiColumnComboBox and the ClientDataSource, so you would be able to easily setup the ClientDataSource.

The benefit of using the ClientDataSource would be using the OnCustomParameter event, which allows you to send various data to the server in the desired format:

Is there an internal build I can try out for the load on demand feature? Between various ajax calls and postbacks in our webforms project, I am unable to get this control working against webservice calls as parameters may change based on other control postbacks. These parameters are also not part of the kendo filter implementation. Load on demand with an ItemsRequested event would work perfectly.

Update:

The Virtualization demo shows how to bind the MultiColumnComboBox to a web-service.

The server-side binding is still not offered by the control and for this reason I am changing the feature request status to "In Development".

Please bear with us for its implementation!

Hi Milind,

The requested virtualization feature is already available. You can test it at https://demos.telerik.com/aspnet-ajax/multicolumncombobox/virtualization/defaultcs.aspx.
