Hi All,

I'm testing your WPF grid and would like to measure Filtering operation for my needs.
But I cannot find appropriate client events, something as:

RecordFilteringChanged
RecordFilteringDropDownOpen
RecordFilteringDropDownPopulated

Could you give me way to do that?

Hello Grego,

Unfortunately the current version of RadGridView does not provide such events. However, you could use the:
grid.ItemsControl.RecordManager.FilterDescription

property, that returns a INotifyPropertyChanged object. You could attach a handler on it to simulate RecordFilteringChanged event. If you want to measure the time needed to populate the distinct values list in the filtering dropdown you could measure the time needed to execute the GetDistinctValues method of the RecordManager class above.

I should not that the upcoming version of RadGridView in a couple of weeks will contain a lot of performance improvements, including improvements in the filtering control, so I would suggest waiting for it before making final decisions about the speed of the control.

Kind regards,
