My UltraWinGrid 7.3 grid, built with .NET3.5 (VS 2008)suffers from performance issues. I have tried the tricks given in http://news.infragistics.com/forums/t/15306.aspx ... this did improve performance, but now, certain grids "Blink" coz the updates coming in are too quick to handle. Here are my questions:
1) If only one cell is updated in a row, is there a way that only that cell is repainted and not the entire row/grid? If not, whats the least expensive way (time wise) of handling real time cell updates?
2) The DataSets im binding as DataSource have atmost 2 relations ... most have none at all. Would I still need to use a BindingSource to bind the DataSets?
Thanks.

The best way to tell is to try it out. I can't say for certain if this will be okay. But any problems you encounter will be immediately obvious. If you bind the grid directly, without using a DataSource, and you can expand down to the lowest level of data and select a row in the grid, I'd say you're safe.
My Grid doesnt have any formulae ... all the values are passed to the server for calculation.
I tried putting a binding source, but it didnt seem to work.
Here's what ive done so far:
1) Currently I directly bind a DataSet as a datasource. These have either 1 or 0 relations. I tried the Binding source with the DataSet name, but that failed.
2) For every Data Source update, I suspend painting and row synchronization and enable it immediately after , but this causes the Grid to blink every now and then. Now I now that each time only a few (2-3) cells are updated, in different parts of the grid, but is this causing the whole grid to be redrawn ?
3) The Cell Display Style is now "Plaintext" for all grids
4) Ive re-used appearances whereever possible
5) My "MaxBandDepth" is 1 or 2 for all the grids.
6) all the data types match (that was always the case)
Is there anything else I can do?
