I have a RadGrid with the default setting of GroupLoadMode="Server". When I click on a group, it collapses, but when I click on it again, it will not expand. Am I missing some setting?

    
                <telerik:RadGrid ID="rgContacts" runat="server"

Hello Anthony,

You are using the default GroupLoadMode which is server. And the same time you have set <ClientSettings AllowGroupExpandCollapse="true">

Try to set <ClientSettings AllowGroupExpandCollapse="false"> or <MasterTableView GroupLoadMode="Client"> and see if this solves the problem.

Do you get any JavaScript error when you click on the expand button? Is postback happening?
