Performance of WinGrid Group By
posted

Hi,

I am working on an application that uses an ultrawingrid attached to a DataView

which is subsequently looking at a DataTable.

I am making use of the ultragrid group by facility to aggregate the figures in the grid.

However, I have some concerns over the performance of using group by. The data in the DataTable

could potentially be updated many times a second. Another option is to use another DataTable with a

data relation to the previous table and use the "expression" property on a column to do the summations.

However, doing this increases the complexity slightly and I lose some of the flexibility of doing it via the grid.

What do you recommend? I have read the article on performance tips (http://news.infragistics.com/forums/t/15306.aspx)

which will no doubt help. Are there any issues with regard to performance of using the group by in a grid?

Many thanks
