What methods should I call to iterate through rows and cell values so it would fire the fewest events etc... for the fastest iteration

Hi Va, I am not sure what iteration methods you are looking for. Please refer this thread and see if that is related to your need. http://www.syncfusion.com/support/forums/message.aspx?MessageID=16755 Also refer this sample that is shipped. Syncfusion\Essential Studio\4.1.0.10\windows\Grid.Windows\Samples\In Depth\GridPopulationSample(also available in earlier versions) Check out Invalidate and Refresh methods. Regards, Stanley

Sorry - I was unclear. I was wondering if calling the same functions through GridControl.Model instead of GridControl (like HideRows[], as well as Model.Data etc..) is faster because it may not fire events?

Hi Va, You can call the CurrentCell.SuspendEvents and SuspendChangeEvents before the routines. It will prevent CurrentCell events. this.gridControl1.CurrentCell.SuspendEvents(); this.gridControl1.SuspendChangeEvents(); this.gridControl1.ResumeChangeEvents(); this.gridControl1.CurrentCell.ResumeEvents(); You can directly access the GridData object instead of using an indexer on the grid. This will avoid events and probably be a factor of 5 - 10 times faster. Please refer this thread for more details. Best Regards, Stanley

Right. But if I use the model to also all the Model.Functions... do all counterpart Model.Functions that have the same name as GridControl.Functions ALSO not call the events?

Hi Va, If HideRows is making things slower then try grid.RowHeights.SetRange method. Grid and Grid.Model has to be the same. Regards, Stanley
