The Cell Validating event only fires when losing input focus (before leaving the current cell) or when Gc Multi Row validates.
The default key setting assigns end edit without leaving the current cell action to the "Enter" key.
But there is no Error Text tooltip when the user moves the mouse over the Error Text icon.3.
We use Html View Define to arrange the columns in 2-row display. You can work around it by using the View Cell Formatting event: Hello Jack, Regarding: 1.
Sometimes the user will just press Esc key to cancel the input value, in this case the Cell Validating event won't get fired and the Error Text will remain shown on the Row Header Column. We often have many columns to be shown in the grid and the user can use horizontal scroll bar to scroll to the region (s)he likes.
When the user scrolls to the right, the Error Text icon will still show up when a cell receives invalid value.
Handle the Cell Validated event to perform post validation processing.So the Cell Validating event cannot be fired when pressing the "Enter" key. The following code example shows how to use this event to validate the cell's value.If you want the Cell Validating event to fire, assign the "Enter" key to the Selection Actions. To run this example, create a windows form, and add a Gc Multi Row control to the form.The runtime throws an Argument Out Of Range Exception.If you submit the change with a Tab (not Enter) it works. We are rerouting this issue to the appropriate group within the Visual Studio Product Team for triage and resolution.
