I am using telerik:RadGrid with one master table and 2 detail table in it. On load of the grid if no detail table exists for the row then also it is displaying > symbol. If we click on that then the symbol will go off becuase no details table exists for that row. This was not the problem in the earlier versions of telerik. But now I have upgraded the telerik version to Version=2010.1.413.40. In this version I am getting problem like this.
Is it version problem or can i fix it in my code?

You can refer the following documentation for hiding expand/collapse images when there is no record.

Could not get it....It is not working. See I have done what is been mentioned in the link. After adding the mentioned code I am not able to remove that hierarchy symbol if no records exists in detail table.

In aspx page.... I have added for masterTable
HierarchyLoadMode
="ServerBind"
Can u please help me????????
Can you please confirm that the conditional check is properly evaluated, and thet the visibility is toggled off as expected - this can be done by putting a breakpoint, and verifying that the code is reached as expected.
