Class DiagramJavaScriptErrorEventArgs

Provides data for JavaScriptError: an exception thrown inside the hosted page's window.SfDiagram wrapper while handling a call from native code (for example, init, addNode, updateLayout).

Inheritance

System.Object

DiagramJavaScriptErrorEventArgs

Namespace: Syncfusion.Maui.Diagram

Assembly: Syncfusion.Maui.Diagram.dll

Syntax

public sealed class DiagramJavaScriptErrorEventArgs : EventArgs

Remarks

Without this, a JavaScript-side failure (a malformed payload, or an environment problem like ej2.min.js failing to load or evaluate) is otherwise invisible: EvaluateJavaScriptAsync gives no signal that the script it ran threw, so nothing renders and nothing on the native side indicates why. See index.html's wrapping of every window.SfDiagram.* call for how this is captured and reported.
