Cell leave cellvalidating examples of girls online dating profiles

Thanks, Depends on what design pattern (if any) you are following.

Technically speaking you should remove your business logic away from your UI layer and have some sort of Validation Object to validate the data in your presentation layer and then post back the results to your view.

I am currently using the Cell Validating event to prevent the cell from updating its value but I'm not able to exit the editing mode.

Here is what the validation method looks like : to get what you want.

In any case, note that it is better to make sure that the cancellation happens only under the expected conditions; otherwise, the code might get stuck in this event because it is automatically called at many different points.

Unforunately it does not seem to work when i try to add a new row to the grid, enter a value and try to leave the cell.

event, value calculates when I leave the next cell.

When the form is loaded the first cell that is selected passes the check with no problem. Ivan.f Private Sub Validate Cell Value(sender As Object, e As Data Grid View Cell Validating Event Args) Handles grd Result.

It is the same for the three cells that are filled on form load. This is not the case with any of the already loaded values.

In Visual basic i'm trying to make a field required by preventing the user to leave the active cell if it's empty. The first one is the ID which is automaticly filled in on adding a new row, the second one is the name.

On form load there are 4 items loaded into the grid.

Best practice is if the row represents and object that is bound say your row represents an order and your grid is bound to a collection of orders .

the cell will be a property in an order you can validate on property changed.

Note: Leaving a cell in the same row is not a problem.
