RadMultiColumnComboBox Object

This article lists the client-side API of RadMultiColumnComboBox and how to use it.

To use the API, you must first get a reference to the control's client-side object. For example:

var rmccbObject = $find("<%=RadMultiColumnComboBox1.ClientID %>");

RadMultiColumnComboBox is a server-side wrapper over the Kendo UI MultiColumnComboBox Widget. Thus, it exposes the API of the underlying Kendo widget. To get a reference to the Kendo widget instance, you can do either of the following:

  • Use the get_kendoWidget() method of the MS AJAX wrapper:


    var rmccbObject  = $find("<%=RadMultiColumnComboBox1.ClientID %>"); //the standard script control object
    var kendoMccbm = rmccbObject.get_kendoWidget(); //the Kendo widget
  • Get the Kendo Widget in its usual way. Make sure to use the $telerik.$ jQuery reference:


    var kendoMccbm = $telerik.$("#<%=RadMultiColumnComboBox1.ClientID %>").data("kendoMultiColumnComboBox"); //the jQuery selector must get the RadMultiColumnComboBox1 wrapper span element

In addition to using the Kendo method directly, you can also use their wrappers that follow the MS AJAX convention through the RadMultiColumnComboBox client object.
