DiagramEditOperation.AddShape Property
In This Article
Identifies the AddShape operation.
#Declaration
TypeScript
static readonly AddShape: string
#Property Value
Type | Description |
---|---|
string | Returns “Add |
#Remarks
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
.
