DiagramEditOperation.DeleteShape Property
In This Article
Identifies the DeleteShape operation.
#Declaration
TypeScript
static readonly DeleteShape: string
#Property Value
Type | Description |
---|---|
string | Returns “Delete |
#Remarks
The operation parameter returns the DeleteShape
value if the RequestEditOperation event fired for the following reasons:
- a user is about to delete a shape,
- the ASPxDiagram control is updating the Cut and Delete command states (for instance, before displaying a context menu).
Use the reason parameter to identify the reason why the event fired.
<dx:ASPxDiagram ID="Diagram" runat="server" Width="100%" Height="600px">
<ClientSideEvents RequestEditOperation="onRequestEditOperation" />
...
if(e.operation === DiagramEditOperation.DeleteShape) {
if(e.args.shape.type === "root") {
if(e.reason !== DiagramRequestEditOperationReason.CheckUIElementAvailability)
showWarning("You cannot delete the 'Development' shape.");
e.allowed = false;
}
...
}
The RequestEditOperation event does not fire for the DeleteShape operation if the AllowDeleteShape property is set to false
.
