Slow Collapse and Expand on grouping

[Phil H.]

My RADGrid is slow while collapsing and expanding in groups.  I noted that it is posting back.  Can post-back be turned off on collapse.  ... what other suggestions?

Hi Phil,

When grouping is handled on the client, groups are expanded client-side, without a postback. To enable grouping on the client, set the GroupLoadMode property of a table view to "Client" and the ClientSettings.AllowGroupExpandCollapse property to True.

Thanks, <MasterTableView GroupLoadMode="Client">  Does the job.
