[Solved] How to check if row value is changed

[Hans Notelteirs]

Hi,

I am trying to find out a way to check if my row has changed. 

Normally on the RowValidating event args you have a property "OldData" which gives you the old data the row is based on.

But when I check this property it is already updated with the new data, so I can't used this to check if the row has changed.

Maybe the old data is updated already because I use TwoWay binding, but when I don't use TwoWay binding, the grid values aren't updated.

Now I'm using a workaround with the CellEditEnded event and compare the NewData and OldData property, but I don't think this is the way. Can somebody tell me which is the way to go? 

Thanks in advance

Hi Hans Notelteirs,

Indeed this is a known issue, you can use OldValues property of the GridViewRowEditEndedEventArgs which is a Dictionary<string, object> where string is GridViewDataColumn.DataMemberBinding.Path and object is the actual value. This property is available with the latest internal binaries.

Hope this helps.

All the best,
