public event NodeDoubleClickEventHandler NodeDoubleClick

Public Event NodeDoubleClick As NodeDoubleClickEventHandler

Event Data

The NodeDoubleClick event's data class is DevExpress.Xpf.Grid.TreeList.NodeDoubleClickEventArgs.

Remarks

The NodeDoubleClick event occurs after a user double-clicks a row. The event parameter’s RowDoubleClickEventArgs.HitInfo property returns the view element that has been double-clicked.

The following code sample copies the node value to the clipboard when a user double-clicks a node.

XAML

<dxg:TreeViewControl x:Name="treeview"
                     ShowAutoFilterNode="True"
                     NodeDoubleClick="treeview_NodeDoubleClick"/>

C#

void treeview_NodeDoubleClick(object sender, DevExpress.Xpf.Grid.TreeList.NodeDoubleClickEventArgs e) {
    if (e.HitInfo.RowHandle >= 0) treeview.CopyToClipboard();
}

VB.NET

Private Sub treeview_NodeDoubleClick(ByVal sender As Object, ByVal e As DevExpress.Xpf.Grid.TreeList.NodeDoubleClickEventArgs)
    If e.HitInfo.RowHandle >= 0 Then treeview.CopyToClipboard()
End Sub
