Need to perform animation in Diagram nodes
2 mins read
Perform animation in Diagram nodes:
In Syncfusion Diagram the animation can be achieved by customizing the node.
The below code shows how to create animation in diagram nodes:
[C#]
public float VolumeLevel
{
get {return m_fVolumeLevel;}
set
{
if (m_fVolumeLevel != value && OnPropertyChanging(this.FullContainerName, "VolumeLevel", value))
{
RecordPropertyChanged("VolumeLevel");
if (value > 80)
value = 20;
if (value < 20)
value = 80;
// set new value
m_fVolumeLevel = value;
// raise property changed event to rendering the node
OnPropertyChanged(this.FullContainerName, "VolumeLevel");
}
}
}
[VB]
Public Property VolumeLevel() As Single
Get
Return m_fVolumeLevel
End Get
Set(ByVal value As Single)
If m_fVolumeLevel <> value AndAlso OnPropertyChanging(Me.FullContainerName, "VolumeLevel", value) Then
RecordPropertyChanged("VolumeLevel")
If value > 80 Then
value = 20
End If
If value < 20 Then
value = 80
End If
' set new value
m_fVolumeLevel = value
' raise property changed event
OnPropertyChanged(Me.FullContainerName, "VolumeLevel")
End If
End Set
End Property
TimerInterval
This property is used to create alerts. Each time it triggers based on an interval period.
[C#]
//initializing alert timer
alertTimer = new System.Windows.Forms.Timer();
//initializing interval period value of alert timer
alertTimer.Interval = 2500;
public int TimerInterval
{
get { return alertTimer.Interval; }
set
{
if (alertTimer.Interval != value)
{
alertTimer.Interval = value;
}
}
}
[VB]
'initializing alert timer alertTimer = New System.Windows.Forms.Timer() ' initializing interval period value of alert timer alertTimer.Interval = 2500 Public Property TimerInterval() As Integer Get Return alertTimer.Interval End Get Set(ByVal value As Integer) If alertTimer.Interval <> value Then alertTimer.Interval = value End If End Set End Property
EnableTimer
This property can used to implement a simple interval timer, which sets off an alarm every interval periods. If the interval is set after the timer has started, the count will be reset to 0.
[C#]
alertTimer.Enabled = true;
public bool EnableTimer
{
get { return alertTimer.Enabled; }
set
{
if (alertTimer.Enabled != value)
alertTimer.Enabled = value;
}
}
[VB]
alertTimer.Enabled = True Public Property EnableTimer() As Boolean Get Return alertTimer.Enabled End Get Set(ByVal value As Boolean) If alertTimer.Enabled <> value Then alertTimer.Enabled = value End If End Set End Property
alertTimer_Tick() Event :
This event can be used to change the value of “VolumeLevel”. The event triggering is based on the value of interval period which is given by the user.
[C# ]
//Registering Event
alertTimer.Tick += new EventHandler(alertTimer_Tick);
void alertTimer_Tick(object sender, EventArgs e)
{
//Change the value of VolumeLevel each time the event is called
this.VolumeLevel = VolumeLevel - 5;
}
[VB]
' Registering Event AddHandler alertTimer.Tick, AddressOf alertTimer_Tick Private Sub alertTimer_Tick(ByVal sender As Object, ByVal e As EventArgs) Me.VolumeLevel = VolumeLevel - 5 End Sub
