Need to disable Edit/Delete/Insert in SPRadGrid Web Part

I need to disable edit/delete/insert functionality from a SPRadGrip web part I am using in my SharePoint 2010 environment. The SPRadGrid Designer does not have checkboxes for these like I have seen on the Demo Page.

I am using version 2010 3.1317.0

 Any input would be helpful. Unfortunately upgrading is not an option, so hopefully my version supports disabling these. I have found that through the header context menu and can hide the edit/delete columns, but these changes do not persist.

Thanks in advance,

Tom
