IRowData Interface

Provides access to the grid’s row data.

Namespace: DevExpress.XamarinForms.DataGrid

Assembly: DevExpress.XamarinForms.Grid.dll

Declaration

public interface IRowData

Related API Members

The following members return IRowData objects:

• CustomSummaryEventArgs.Row
• DataGridView.GetRow(Int32)
• GridColumnDataEventArgs.RowData

Remarks

The grid’s GetRow method returns an object that implements the IRowData interface. Use the IRowData.Item property to get an object that represents a data source’s record to which the grid’s row corresponds. To get a value of the specified field in the row, call the IRowData.GetFieldValue method.

Example

This example shows how to set up the grid to display the Edit Values form when a user taps a cell. The grid is bound to a collection of orders.

1. Subscribe to the DataGridView.Tap event.

   XAML

   <dxg:DataGridView x:Name="grid" ItemsSource="{Binding Orders}" Tap="Grid_Tap">
       <dxg:DataGridView.Columns>
           <dxg:TextColumn FieldName="Product.Name" Caption="Product" />
           <dxg:NumberColumn FieldName="Product.UnitPrice" Caption="Price" DisplayFormat="C0"/>
           <dxg:NumberColumn FieldName="Quantity" />
           <dxg:NumberColumn FieldName="Total" 
                             UnboundType="Integer" UnboundExpression="[Quantity] * [Product.UnitPrice]" 
                             IsReadOnly="True" DisplayFormat="C0" />
           <dxg:DateColumn FieldName="Date" DisplayFormat="d" />
           <dxg:CheckBoxColumn FieldName="Shipped" />
       </dxg:DataGridView.Columns>
   </dxg:DataGridView>
   

2. In the event handler:

   1. Create an EditFormPage instance with the grid and data source’s record object to which the grid’s current row corresponds passed as constructor parameters.

   2. Call the Navigation.PushAsync method and pass the created page as a parameter.

      C#

      using Xamarin.Forms;
      using DevExpress.XamarinForms.DataGrid;
      
      namespace DataGridExample {
          public partial class MainPage : ContentPage {
              public MainPage() {
                  InitializeComponent();
              }
      
              private void Grid_Tap(object sender, DataGridGestureEventArgs e) {
                  if (e.Item != null) {
                      var editForm = new EditFormPage(grid, grid.GetRow(e.RowHandle).Item);
                      Navigation.PushAsync(editForm);
                  }
              }
          }
      }
      

3. In the App.xaml.cs file, assign a NavigationPage instance to the Application.MainPage property and add the MainPage content page to the navigation stack (the application’s root page):

   C#

   namespace DataGridExample {
       public partial class App : Application {
           public App() {
               InitializeComponent();
   
               // MainPage = new MainPage();
               MainPage = new NavigationPage(new MainPage());
           }
   
           // ...
       }
   }
   

The grid now displays the Edit Values form when a user taps a data cell.
