Namespace: DevExpress.Utils.VisualEffects

Assembly: DevExpress.Utils.v23.2.dll

NuGet Packages: DevExpress.Utils, DevExpress.Wpf.Core

Declaration

C#

[DXCategory("Events")]
public event MouseEventHandler Click

VB.NET

<DXCategory("Events")>
Public Event Click As MouseEventHandler

Event Data

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

Property	Description
Button	Gets which mouse button was pressed.
Clicks	Gets the number of times the mouse button was pressed and released.
Delta	Gets a signed count of the number of detents the mouse wheel has rotated, multiplied by the WHEEL_DELTA constant. A detent is one notch of the mouse wheel.
Location	Gets the location of the mouse during the generating mouse event.
X	Gets the x-coordinate of the mouse during the generating mouse event.
Y	Gets the y-coordinate of the mouse during the generating mouse event.

Remarks

The code snippet below utilizes the CalcHitInfo method to identify the clicked element, and hides this element if it is “badge1”.

C#

private void AdornerUIManager1_Click(object sender, MouseEventArgs e) {
    AdornerUIManager manager = sender as AdornerUIManager;
    var hitInfo = manager.CalcHitInfo(e.Location);
    if (hitInfo.Element==badge1)
        badge1.Visible = false;
}

VB.NET

Private Sub AdornerUIManager1_Click(ByVal sender As Object, ByVal e As MouseEventArgs)
    Dim manager As AdornerUIManager = TryCast(sender, AdornerUIManager)
    Dim hitInfo = manager.CalcHitInfo(e.Location)
    If hitInfo.Element=badge1 Then
        badge1.Visible = False
    End If
End Sub

Important

In Ribbon and Toolbars, users see links of BarItem objects at runtime. If the TargetElement of an Adorner Element is a Bar Item, the Adorner Manager creates shadow copies of this Element for each of the Item Links associated with this Bar Item. For this reason, the hitInfo.Element property returns an object that differs from the source Adorner Element. To avoid confusion, we recommend that you handle the Click event of a specific Element instead of the parent manager’s Click event.
