Customizing Appearance on Rendering with using NodeCollectionChange Events
Customizing Appearance on Rendering While Using NodeCollectionChanged Events
Syncfusion® Diagram supports customizing the appearance of the node using the NodeCollectionChanged events. Using the NodeCollectionChanged events the node can be customized.
The below code shows how to customize the appearance of the node.
[C#]
// Registering NodeCollectionChanged Event
diagram2.EventSink.NodeCollectionChanged += EventSink_NodeCollectionChanged;
// Customizing the Appearance of the node
void EventSink_NodeCollectionChanged(CollectionExEventArgs evtArgs)
{
if (evtArgs.Elements is NodeCollection || evtArgs.Element is Node)
{
if (evtArgs.Elements is NodeCollection)
{
NodeCollection NodeColl = (NodeCollection)evtArgs.Elements;
foreach (Node N in NodeColl)
{
// Customizing Node's Line Color and Width
N.LineStyle.LineColor = Color.Red;
N.LineStyle.LineWidth = 2;
}
}
else
{
Node Nod = (Node)evtArgs.Element;
Nod.LineStyle.LineColor = Color.Red;
Nod.LineStyle.LineWidth = 2;
}
}
}
[VB]
' Registering NodeCollectionChanged Event
Private diagram2.EventSink.NodeCollectionChanged += AddressOf EventSink_NodeCollectionChanged
' Customizing the Appearance of the node
Private Sub EventSink_NodeCollectionChanged(ByVal evtArgs As CollectionExEventArgs)
If TypeOf evtArgs.Elements Is NodeCollection OrElse TypeOf evtArgs.Element Is Node Then
If TypeOf evtArgs.Elements Is NodeCollection Then
Dim NodeColl As NodeCollection = CType(evtArgs.Elements, NodeCollection)
For Each N As Node In NodeColl
' Customizing Node's Line Color and Width
N.LineStyle.LineColor = Color.Red
N.LineStyle.LineWidth = 2
Next N
Else
Dim Nod As Node = CType(evtArgs.Element, Node)
Nod.LineStyle.LineColor = Color.Red
Nod.LineStyle.LineWidth = 2
End If
End If
End Sub
