Hi!

I'm trying to implement the following behaviour. I have an editable grid - if the user changes a value i want to show him a warning with the posibility of accepting or canceling that change. This is how i implemnted it :

void grid_BeforeCellUpdate(object sender, BeforeCellUpdateEventArgs e) {

            if (grid.ActiveCell.Column.Key == "COL") {

                try {

                    MessageBoxButtons btns = MessageBoxButtons.YesNo;

                    if (MessageBox.Show("If you change this all child values will be erased automatically. Are you sure you want to do this ? ", "Warning", btns) == System.Windows.Forms.DialogResult.No) {

                        e.Cancel = true;

                    }

                    else {

                        UpdatedContractRows.Add(e.Cell.Row);

                    }

                }

                catch (Exception ex) {

                    MessageBox.Show(ex.Message);

                    e.Cancel = true;

                }

            }

        }

The problem is the following - if i click yes, the value is commited and it changes in the cell's value - as it should be. But, if i click No, the message box appears again and i have to click No again. only after that it cancels the event and the cell returns to the initial value.

Any ideea how can i fix this ?

Thank you!
