Answer 1

The error is because your are using plain javascript for finding radgrid(telerik controls).
The javascript used for telerik contols is different than the normal javascript for html contols:
To find radgrid with id="grdTeste":
var grdTeste=$find("<%=grdTeste.ClientID%>"); //find radgrid
This will help you to work with radgrid on client side:
