I recently upgraded my application from Spread 2.5.2007 to 2.5.2011. I have code that attempts to validate user's input into a cell. It does this by adding an event handler in the EditModeOn event as shown in the following example:
myGrid.EditingControl.Validating += new System.ComponentModel.CancelEventHandler(this.MyValidatingHandler);
When the validation event handler fires, and I can set the CancelEventArg's .Cancel property to true if there is a validation error, and the cell will stay in edit mode.
However, with 2.5.2011, this no longer works and the cell always leaves the edit mode. I just tried Spread 2.5.2009 and it is working fine, so the bug was introduced in either 2010 or 2011.
