public event EventHandler<PathIconEventArgs> CustomPathIcon
Public Event CustomPathIcon As EventHandler(Of PathIconEventArgs)
The CustomPathIcon event's data class is PathIconEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| 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. |
| Icon | Gets or sets the path icon. |
| OriginalSource | Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs. |
| Path | Gets the path displayed in the BrowsePathEdit. |
| RoutedEvent | Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs. |
| Source | Gets or sets a reference to the object that raised the event. Inherited from RoutedEventArgs. |
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. |
The following code sample changes the icon displayed if a user enters an invalid path:
<dxe:BrowsePathEdit DialogType="Folder" CustomPathIcon="OnCustomPathIcon">
using DevExpress.Xpf.Editors;
using System.IO;
using System.Windows.Media.Imaging;
// ...
void OnCustomPathIcon(object sender, PathIconEventArgs e) {
if (!Directory.Exists(e.Path))
e.Icon = new BitmapImage(new System.Uri("pack://application:,,,/Warning_16x16.png"));
e.Handled = true;
}
Imports DevExpress.Xpf.Editors
Imports System.IO
Imports System.Windows.Media.Imaging
' ...
Private Sub OnCustomPathIcon(ByVal sender As Object, ByVal e As PathIconEventArgs)
If Not Directory.Exists(e.Path) Then e.Icon = New BitmapImage(New System.Uri("pack://application:,,,/Warning_16x16.png"))
e.Handled = True
End Sub
