Hi all,
I am attempting to create a Rad grid (version 2010.3.1215.40 in Visual Studio 2010 ) which returns a list of contacts. Each contact may have a number of 'profiles' representing how we know a person. For example, We may have a contact called Joe blogs, he could have two profiles, one which links him to Company A and one which links him to Company B (ie a contractor/consultant). A user needs to be able to select the profile id from the list of contacts, however we wish to only display the nested detail table if there is more then 1 profile. If there is only 1 profile then the user should just see that in the main grid.
So far I have the grid set up to display the full list of contacts and then they have the nested grid of profiles, however a user can currently expand a row even if it has 1 or 0 profiles. Any sugestions on how to not display the nested grid where the profile count is less then 2?
Many Thanks

Sorry, never mind. I have just found it in the documentation.
http://www.telerik.com/help/aspnet-ajax/grid-hide-expand-collapse-images-when-no-records.html
However, now all the master tables rows have their images hidden despite having a number of profiles
EDIT:
Solved. I was assigning the datasource to the detail table only when the row being expanded posted back. The count was therefore always going to be 0 (or perhaps nothing) as the preload event fired before that point . By setting the HierarchyLoadMode to Server, all the binds were then done as the gridloaded and therefore before the preload event checked the count.
