If something else, is it your own extension of Binding List (most custom classes would need to extend Binding List in order to get sorting)?

Built-in validations through IData Error Info, INotify Data Error Info and Data annotation attributes, can be enabled by setting Sf Data Grid. Sf Data Grid will not allow user to edit other cell / row if validation failed.However, Sf Data Grid provides an option to achieve the validation by adding the validation template.I am having trouble determining when my Data Grid View object is sorting (based on a column header click).Although you found a workaround, at a high level it seems to me such a workaround should not be needed...unless you customized the Cell Formatting event on the initial load, but somehow the same Cell Formatting event is not getting called when you sort.The Cell Formatting event should really only be used as a last resort for customizations that cannot be cached in a Default Cell Style (and there are several...I guess the Column Header Mouse Click would still be raised, but by setting that Sort Mode there would be no glyph there asking to be clicked.

Of course, this then begs the obvious and perhaps simplest solution..not just check which column was clicked before firing off the splash screen..not fire it for the columns which you have determined that ultimately do not fire a Grid. It was so much that I *didn't* want them sorted, as they just didn't sort.

- But assuming you are binding to a Data View (the underlying IBinding List of the Data Set) then what happens is on the left-click of the column header cell, if sorting is enabled, the Grid calls (IBinding List)Default View.

Apply Sort(Property Descri ptor[which is the column name], Sort Direction [the sort glyph]); Only once inside that method can you really be guaranteed the Grid is actually sorting.

The idea is, in a large table, sorting the columns takes time, so I show a splash screen.

When it is done sorting I want the splash screen dissapear.

You can validate the cells using Current Cell Validating event when the cell is edited. You can show the error information in row header by setting IData Error Info. Master-Details View support to validate the cells and rows using Current Cell Validating and Row Validating events.
