How to enable annotation edit mode in ASP.NET Core Diagram?

To enable annotation edit mode after a node is dropped from the symbol palette onto the ASP.NET Core Diagram, you can follow these steps:

Configure the Drop Event:

• Handle the drop event, which is triggered when an element is dropped from the symbol palette to the diagram canvas.

Call the startTextEdit Method:

• Within the drop event handler, call the startTextEdit method of the diagram.
• The startTextEdit method initiates the editing mode for the associated annotation of the dropped node or connector.
• This allows users to directly modify the text of the dropped node or connector.

Refer to the code sample of the above steps:

<ejs-diagram id="diagram" width="100%" height="469px" getnodedefaults="@ViewBag.getNodeDefaults" drop="dropFn" getconnectordefaults="@ViewBag.getConnectorDefaults" nodes="ViewBag.Nodes" connectors="ViewBag.Connectors" created="fitToPage">
</ejs-diagram>

function dropFn(args){
 var diagram = document.getElementById("diagram").ej2_instances[0];
 diagram.startTextEdit();
}
