Event Data

The AddingNewRow event's data class is AddingNewEventArgs. The following properties provide information specific to this event:

Property	Description
NewObject	Gets or sets the object to be added to the binding list.

Remarks

The AddingNewRow event occurs before the GridControl adds a new record to your data source. In this event handler, you can specify a data object and initialize its values.

XAML

<dxg:GridControl>
    <dxg:GridControl.View>
        <dxg:TableView NewItemRowPosition="Top" 
                       AddingNewRow="view_AddingNewRow" />
    </dxg:GridControl.View>
</dxg:GridControl>

C#

void view_AddingNewRow(object sender, System.ComponentModel.AddingNewEventArgs e) {
    e.NewObject = new Product(selectedCompany) {
        ProductName = "", 
        CompanyName = "New Company", 
        UnitPrice = 10, 
        Discontinued = false 
    };
}

VB.NET

Private Sub view_AddingNewRow(ByVal sender As Object, ByVal e As System.ComponentModel.AddingNewEventArgs)
    e.NewObject = New Product(selectedCompany) With {
        .ProductName = "",
        .CompanyName = "New Company",
        .UnitPrice = 10,
        .Discontinued = False
    }
End Sub

Note

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

Refer to the following topic for information on how to add a new row to the GridControl: New Item Row.

If you want to maintain a clean MVVM pattern and specify a new data record in a View Model, create a command and bind it to the AddingNewRowCommand property.
