DiagramEditOperation.AddShape Property

Identifies the AddShape operation.


static readonly AddShape: string

Property Value

Type Description

Returns “AddShape”.


The operation parameter returns the AddShape value if the RequestEditOperation event fired for the following reasons:

  • a user is about to add a shape,
  • the ASPxDiagram control is updating the Paste command state (for instance, before displaying a context menu).

Use the reason parameter to identify why the event fired.

<dx:ASPxDiagram ID="Diagram" runat="server" Width="100%" Height="600px">
    <ClientSideEvents RequestEditOperation="onRequestEditOperation" />
function onRequestEditOperation(s, e) {
    if(e.operation === DiagramEditOperation.AddShape) {
        if(e.args.shape.type !== "employee" && e.args.shape.type !== "team") {
            if(e.reason !== DiagramRequestEditOperationReason.CheckUIElementAvailability)
                showWarning("You can add only a 'Team' or 'Employee' shape.");
            e.allowed = false;

The RequestEditOperation event does not fire for the AddShape operation if the AllowAddShape property is set to false.
