Hi,

the summary dialog enables me only to check the Count summary type while others are disabled. Setting summary for the grid via API, i.e. 

SummarySettings maxSummary = e.Layout.Grid.DisplayLayout.Bands[0].Summaries.Add(tmpCol.Key, SummaryType.Maximum, tmpCol);

works fine and grid displays sum, max, min etc.

What's wrong there? I supoose there is a problem reading data type for columns in the underlying DataTable, am I wrong? 

Thanks
