I have a custom grouping summary for a particular column (Lets call it column A). I set the properties (formatting, forumla, etc) in the "InitializeLayout" event, but when the grid loads up column A does not show any grouping summary for that column (even though I know for sure that my custom function gets called). I also rigged up a button on the form to add more grouping summaries to the grid when pressed, when the extra summaries are added column A finally shows the grouping summary. Why does it do this? I want column A's grouping summary to appear right when the grid is loaded with data.
