Topic: Add and Remove Rows

The AddingNewRow event fires when a new row is added to a grid using any of the control means. To initialize a new row, assign the initialized record to event arguments’ NewObject property.

Note

The AddingNewRow event does not fire when you add a new row directly to a bound data source.

The code sample below demonstrates how to initialize cells displayed within the New Item Row with default values:

XAML

<dxg:GridControl Name="grid">
    <dxg:GridControl.View>
        <dxg:TableView Name="view" NewItemRowPosition="Top" AddingNewRow="AddingNewRow" />
    </dxg:GridControl.View>
</dxg:GridControl>

C#

void view_AddingNewRow(object sender, System.ComponentModel.AddingNewEventArgs e) {
    e.NewObject = new Person(1);
}

VB.NET

Private Sub view_AddingNewRow(ByVal sender As Object, ByVal e As System.ComponentModel.AddingNewEventArgs)
    e.NewObject = New Person(1)
End Sub
