Based on RadioButtonList's selection, I determine the datasource of the RadGrid.
I have AutoPostBack to true for the RadioButtonList and do a Rebind in SelectedIndexChanged of RadioButton and it displays the data from different sources in the RadGrid just fine.
However, in the pager section, its not refreshing the number of items.
That is, say datasource A has 50 records and B has 100 records. Choosing between different radiobutton, it displays the records from A and B. But in pager section, it always shows number of items from datasource A.
