TableView.RowDoubleClick Event

Occurs when a user double-clicks a row.

Namespace: DevExpress.Xpf.Grid

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

NuGet Package: DevExpress.Wpf.Grid.Core

Declaration

C#

public event RowDoubleClickEventHandler RowDoubleClick

VB.NET

Public Event RowDoubleClick As RowDoubleClickEventHandler

Event Data

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

Property	Description
ChangedButton	Gets a mouse button that has been pressed twice.
Handled	Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. Inherited from RoutedEventArgs.
HitInfo	Gets or sets the information on a view element located under the mouse pointer.
OriginalSource	Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs.
RoutedEvent	Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs.
Source	Gets the View that raised the event.

The event data class exposes the following methods:

Method	Description
InvokeEventHandler(Delegate, Object)	When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. Inherited from RoutedEventArgs.
OnSetSource(Object)	When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. Inherited from RoutedEventArgs.

Remarks

The HitInfo property returns information about a view element that a user double-clicks. Refer to the following topic for more information: Hit Information.

If you want to maintain a clean MVVM pattern and process the row double-click operation in a View Model, create a command and bind it to the RowDoubleClickCommand property.

Example

The following example demonstrates how to use the TableView.RowDoubleClick event to process double-clicks:

View Example: How to Handle Row Double-clicks

MainWindow.xaml

<dxg:GridControl x:Name="grid">
<!-- ... -->
    <dxg:GridControl.View>
        <dxg:TableView RowDoubleClick="OnRowDoubleClick"/>
    </dxg:GridControl.View>
</dxg:GridControl>

MainWindow.xaml.cs

void OnRowDoubleClick(object sender, RowDoubleClickEventArgs e) {
    int rowHandle = e.HitInfo.RowHandle;
    if(rowHandle == GridControl.InvalidRowHandle)
        return;
    if(grid.IsGroupRowHandle(rowHandle))
        MessageBox.Show("A group row has been double clicked.", "Info");
    else
        MessageBox.Show("A data row has been double clicked.", "Info");
}

MainWindow.xaml.vb

Private Sub OnRowDoubleClick(ByVal sender As Object, ByVal e As RowDoubleClickEventArgs)
    Dim rowHandle As Integer = e.HitInfo.RowHandle
    If rowHandle = GridControl.InvalidRowHandle Then
        Return
    End If
    If grid.IsGroupRowHandle(rowHandle) Then
        MessageBox.Show("A group row has been double clicked.", "Info")
    Else
        MessageBox.Show("A data row has been double clicked.", "Info")
    End If
End Sub
