Server side filter parsing

[JT]

I would like to send the text of the combos input into the querystring (?text=abc) when server-side filtering. How can I accomplish this with the wrapper? Alternatively, is there code provided for parsing default query string information?

[JT]

I found a way to do this clientside by doing the following:

 

var combo = $("#combo").data("kendoMultiColumnComboBox");

combo.dataSource.transport.options.read.data = function () {
    return { text: $("#combo").data("kendoMultiColumnComboBox").text() }
};

 

Wondering if there is a way to do this server side in the control markup? Worst case I can use the ScriptManager to add it to every server side multi column combobox.

Hello JT,

Until the server-side filtering via ItemsRequested event is implemented, you can use the ClientDataSource as suggested in the feedback portal item: 

• https://feedback.telerik.com/aspnet-ajax/1400066-load-on-demand-or-virtualization-feature-for-multicolumncombobox; 

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:
