Hi,

This is a duplicate post since i have not heard any acknowledgement (http://ko.infragistics.com/community/forums/t/83474.aspx)

Can someone please confirm if this is a bug? Again i see the same behavior if virtualization is on or off  so please ignore the subject line of the previous post

See attached sample

Summary:

If we set "ShouldRefreshOnDataChange" to false, and add a single row to the grid the cpu takes only 3-4% on my box.

If we set "ShouldRefreshOnDataChange" to true, and add a single row, the cpu takes 25% (i.e. one full core)

Try running the attached sample by turning on/off the above property in (TabItem1.xaml.cs) line 51

Per your documentation "ShouldRefreshOnDataChange - Get / set whether this rule needs to reaquire data due to cell value being changed", so it should render only the cell/row which is updated, but apparently as per the trace i see all cells are being repainted in the view port.

Could you please take this urgently with devs and update me if it is a bug and if so when it can be patched? We need conditional formatting, otherwise can you please let me know if there is any other way i can style a row manually when a particular property changes?
