Problem to get datasource is "null" or “not an object” for kendo drop down list in Internet explorer 8 with compatibility view mode on

[Prashant]

After submitting form We are getting dropdown is undefined with an error datasource object is “null” or “not an object”

We are using dropdown component as below code

Examples:

var dropdown = $("#cboxLoadedContent #connection_mode").data("kendoDropDownList");

dropdown.dataSource.data([{text:'Connection Mode',value:'0'},{text:'Local Files',value:'localfiles'}]);

This is happened only on internet explorer 8 with compatibility view mode on/lower version of internet explorer browser.
It working properly with mozila 9 and Internet explorer 8.

Thanks in advaced.
