Don't Add New Row, on validation fails

[crazy05]

I am using Interaction trigger on RowEditEnded. If the user enter invalid value, I want to remove that row from the Grid. How can I do this ?

ItemsSource="{Binding ItemSource,Mode=TwoWay }"

 <i:Interaction.Triggers>
                    <i:EventTrigger EventName="RowEditEnded">
                        <cmd:EventToCommand Command="{Binding EditingCommand}" />
                    </i:EventTrigger>
                </i:Interaction.Triggers>

 

 if (this.ItemSource.Count > 0)
            {
                var newItem = this.ItemSource.FirstOrDefault(d => d.ItemOrder == null);

                if (newItem != null)
                {
                    if (newItem.Id > 0)
                    {
                       newItem .ItemOrder = this.ItemSource.Count;
                    }
                    else
                    {
                        this.ItemSource.Remove(newItem );
                    }   
                }
            }

Hi Ram,

You have to work with the source collection that the grid is bound to. If you have ObservableCollection<Club> Clubs for example in your ViewModel that is the source of the grid, you can just remove the item from it and the grid will reflect the changes.
