I haven't supported every grid event, the log would be less useful if it were clogged up with all of them, but I've included the major navigation and validation events.

Using the Code The code isn't complicated, and I'm not intending this article to be a grid programming tutorial so I won't go into it in detail. That allows navigation of the grid without slipping into edit mode. If you want to support others, add a handler for the new event and follow the steps above. Both of these types give you access to the current Rowlndexand Columnlndex, and they have aCancel property that can be set toTRue to cancel validation. I think you get the idea. Additional Leave events may occur, depending on where we move to. Optionally modify a flag in the event arguments to indicate some behaviour specific to that event.

The DataGridView control is designed to keep the focus on the current cell if validation fails. If you're not interested in the events I've supported, just delete the handler. Row Fail - When clicked, the Row Fail state is enabled. Finding that some event Vs in "DataGrid" has been cancelled in the new controls in DataGridView, but many of the "Cell" event, it's got a large head, is not understand successively trigger sequence of events. This helps identify when, and in what order, events are being handled without explicitly having to set breakpoints and wait for the code to catch each event. So write a small program, used to test commonly used Cell events and sequence. The event triggered time sequence diagram as follows, because the CellEnter is the first to be triggered, subsequent events, are triggered by the artificial, so the time interval is a little long. CellBeginEdit —In the selected cells into edit mode. CellValidated - complete data validation to cell. Whenever an OnValidating event is handled, the handler will set the cancel flag to indicate validation failure. These events let you modify the displayed data as it goes out to and comes in from the data source, respectively. The OnCellLeave event will always occur when an attempt is made to navigate away from a cell. AddEvent with a string to be displayed in the log.

  1. Understanding DataGridView Events Let's take a high level view of the event sequences and follow it up with a description of the state machine included in the downloads. So the validation logic you apply in a handler for theCellValidating event should validate against the display patterns for the cell, which don't necessarily map directly to the storage patterns for the corresponding data member in the data source.

  2. Get network issues from WhatsUp Gold. With respect to validation, you should be aware that the CellValidating event fires before the CellParsing event.
