Hello,
Thank you for your question.
We kindly suggest using a global variable:
var disableContextMenu = true;
flexmonster.customizeContextMenu(function(items, data, viewType) {
return (disableContextMenu)?[]:items;
});
Here is a JSFiddle example for illustration: https://jsfiddle.net/flexmonster/ts57bw9n/.
Please let us know if you have any questions.
Best Regards,

Hi Vera,
I tried this with angular 5. I have a class level variable but I can not access inside customizeContextMenu function.
I am using like -'this. disableContextMenu', but 'this' does not refers to the component class.
e.g.
onPivotReady(pivot: Flexmonster.Pivot): void {
this.pivot.customizeContextMenu=this.onCustomizeContextMenu.bind(this);
}
public onCustomizeContextMenu(items, data, viewType) {
return this.disableContextMenu)?[]:items; // 'disableContextMenu is undefined here as 'this' refers to something else not the class.
}
please guide if I am doing something wrong here.

Hello, Devesh,
Thank you for writing to us.
We kindly advise creating a separate property (customizeContextMenuHandler) which will refer to the function (onCustomizeContextMenu) in app.component.ts:
customizeContextMenuHandler = (a,b,c) => {return this.onCustomizeContextMenu(a,b,c);}
onCustomizeContextMenu(items: Flexmonster.ContextMenuItem[], data: Flexmonster.CellData | Flexmonster.ChartData, viewType: string): Flexmonster.ContextMenuItem[] {
return (this.disableContextMenu ? [] : items);
}
Then in app.component.html refer to the defined handler property:
<fm-pivot#pivot
[toolbar]="true"
[width]="'100%'"
[height]="500"
[report]="pivotReport"
[customizeContextMenu]="customizeContextMenuHandler"
(ready)="onPivotReady($event)"
(reportcomplete)="onReportComplete($event)">
</fm-pivot>
The disableContextMenu class level variable should be available if defined in the class scope, for example in app.component.ts:
export class AppComponent {
public disableContextMenu = true;
...
}
Please let us know if the above suggestion helps.
Best Regards,
Vera
