static readonly ChangeShapeText: string

Property Value

Type Description

Returns “ChangeShapeText”.


The operation parameter returns the ChangeShapeText value if the RequestEditOperation event fired because a user changed a shape’s text.

<dx:ASPxDiagram ID="Diagram" runat="server" Width="100%" Height="600px">
    <ClientSideEvents RequestEditOperation="onRequestEditOperation" />
function onRequestEditOperation(s, e) {
    if(e.operation === DiagramEditOperation.ChangeShapeText) {
        if(e.args.text === "") {
            if(e.reason !== DiagramRequestEditOperationReason.CheckUIElementAvailability)
                showWarning("A shape text cannot be empty.");
            e.allowed = false;

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