CellDataError event not fired

Steve posted over 13 years ago

Hello,

I read on the online help that the CellDataError event is fired after the BeforeExitEditMode is fired. I also read that the CellDataError event is not fired when the BeforeExitEditMode event is cancelled.

My issue is the following:

I have a textbox cell that will validate the input with the CellDataError event, and will notify my controller class of a change in the textbox cell via the CellChange event. Whats happening is the following:

When the user types in a value, whether valid or invalid, the CellChange event fires, but the CellDataError does not. My first assumption was that the event is being canceled so I tried using the EventManager.AllEventsEnabled = true; but that does not work either.

Anyone have an idea how to use both? I need the following sequence of events: 1- if the values are not with in the specified range of the regular expression pattern, the fire the CellDataError 2- if the values are with in the range, fire the CellChange event.

Thanks!

CellDataError fires when the user leaves the cell, not on each key press. It sounds like you want to validate in response to the CellChange event instead.

I'm having problems with CellDataError event,I don't get why but when I delete a row on ultragrid after that CellDataError event does not fire, I saw AfterCellUpdate and other events fire but only CellDataError event does not fire.

Hi Ximki,

I'm not sure I follow you. Why would CellDataError fire when deleting a row? Those two events aren't really connected and there's no reason why CellDataError should ever fire while deleting a row. A cell data error in a row that's about to be deleted is irrelevant.

Unless you are saying that after you delete a row, the CellDataError event is never firing again, even for cell's that do have errors. But if that's the case, I've never heard of anything like that. I don't see any way that could possibly happen. If that's the case, my only guess is that your code is somehow unhooking the event or something.

yes it was the second case, if I delete 1 row then after that CellDataError event does not fire anymore, but I managed it on BeforeCellDeactivate event like this:

private void ultragrid1_BeforeCellDeactivate(object sender, CancelEventArgs e)
        {

            if (ultragrid1.ActiveCell.Column.Key == "PartnerName")
            {
                if (!ControlForExistingPartner(ultragrid1.ActiveCell.Value.ToString()))
                {
                    MessageBox.Show(this, rm.GetString("ItemsNotExists"), rm.GetString("msgError"), MessageBoxButtons.OK, MessageBoxIcon.Error);
                    if (ultragrid1.ActiveCell != null)
                    {
                        BeginInvoke(new MethodInvoker(() =>
                        {
                            ultragrid1.ActiveCell.Activate();
                            ultragrid1.PerformAction(UltraGridAction.EnterEditMode);

                        }));

                    }
                    e.Cancel=true;
                }
            }
        }

thanks for reply Mike.
