I have a very basic RadGrid implemented with 1 master table and 1 detail table connected via a <ParentTableRelation>. I have the grid set to HierarchyLoadMode="Client" and the load time on the page is somewhere in the neighborhood of 1 minute plus.

Am I doing something wrong? 500+ rows doesn't seem like a ton to me for a grid to handle. Are there settings I can alter to make this work?

Paging won't work for my situation either.

Hi Craig,

500+ rows with client hierarchy actually means that

1) you databind 1 master table AND 500+ detail tables simultaneously, which is bad for the server-side performance
2) all detail tables are rendered on the client, which means that you have several THOUSAND rows rendered and this is bad for the client-side performance

I am afraid you are pushing to the limit in this case. You either need to use paging or use ServerOnDemand hierarchy load mode.

Best wishes,
