GridViewBase.AddingNewRowCommand Property

Gets or sets a command that is executed before a new row is added to the GridControl.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v21.2.dll

Declaration

public ICommand<NewRowArgs> AddingNewRowCommand { get; set; }

Property Value

Type Description
DevExpress.Mvvm.ICommand<NewRowArgs>

A command that is executed before a new row is added to the GridControl.

Remarks

Bind a command to the AddingNewRowCommand property to maintain a clean MVVM pattern. The command works like an AddingNewRow event handler and allows you to specify a new data record in a View Model.

A command bound to the AddingNewRowCommand property is executed before the GridControl adds a new record to your data source. In this command, you can specify a data object and initialize its values.

<dxg:GridControl>
    <dxg:GridControl.View>
        <dxg:TableView NewItemRowPosition="Top" 
                       AddingNewRowCommand="{Binding AddingNewRowCommand}"/>
    </dxg:GridControl.View>
</dxg:GridControl>
[Command]
public void AddingNewRow(NewRowArgs args) {
    args.Item = new Product(selectedCompany) {
        ProductName = "", 
        CompanyName = "New Company", 
        UnitPrice = 10, 
        Discontinued = false 
    };
}

Note

The AddingNewRowCommand property does not call the bound command 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.
