At a customers request, I am trying to have a RadGrid go into edit mode on a mouse click in a grid row and update the item when another row is selected or the 'Enter' key is pressed. I got it all to work, except that the grid has a details table that wants to expand or collapse when the 'Enter' key is pressed, which is visually unappealing. I have the HierarchyLoadMode of the master table view set to 'Client'. I have not been able to find a setting in the grid object model (I'm building this as a SharePoint web part, so everything is C# code behind using the RadGrid objects) that disables this behaviour. Does anyone know how to disable this?
