Hi Mr.Moo,

About jqxButton you can have only disabled as an observable property.
The value can be true or false.

Hello ivailo, that’s great news and all I really want to be honest, but can you tell me how I do this for a button created dynamically as shown in the jqxGrid with Statusbar example as I see no data binding references in the button’s API documentation.

Hi Mr.Moo,

This code probably will be helpful:

Hello again,

apologies for the delay in replying. I have tried the above example but the buttons still work as expected. For example, if you change the initial values thus:

this.disabledButtonAdd = ko.observable(true);
this.disabledButtonDelete = ko.observable(true);

Then load the page you can still add and delete the items when you click what appears to be a disabled button! Also, how would you change the value of this.disabledButtonDelete at runtime?

Hello Ivailo,

This works for me thank you very much. I’ll make some changes to my code so I can hopefully make use of this approach.
