When a RadGrid has the "AllowScroll" property set to True and is populated via a DataSourceID, calling the ExportToExcel() method on the grid results in the grid immediately rebinding. This undoes any changes made to the grid, like during the recommended way to export Template columns. When AllowScroll=False, the grid does not rebind and Template columns are exported, as expected.

While changing the value from RadCombox, meaning firing the SelectedIndexChanged, I am getting the below error.

Exception information:

When trying on localhost SelectedIndexChanged of RadCombobox is getting fired and rgrid_NeedDataSource of RadGrid is not fired but when deployed on IIS, the scenario is opposite, SelectedIndexChanged is not fired but rgrid_NeedDataSource is getting fired.

Please help.

Also another thing, I wanted to understand how to use licenses.licx file in our project for telerik dll version 2013.1.314.45?
