Data-Bind to Description property.

[merseysider85Member]

Hello there,
I’m using jqxchart with knockout model-view.
Recently we decided to bind sales amount to the description of jqxChart slide.

<div style="width:1024px;height: 750px"> 0) {
                return self.departments()[0].saleAmountToday();
            }
        },
        write: function (value) {
            //nothing
        },
        owner: self
    });   

After investigation i realized that at the first time that “self.amountToday” of view model been called, self.departments() is not initialized yet, and therefore description is “undefined”.

Right after the first call, there is another call to “self.amountToday”, and now i can see in debug mode that
self.departments()[0].saleAmountToday() initialized but description is still “undefined”.

My question is if Description property can handle Data-Bind from knockout model view.

I’m sorry, the code not presented well,
this is the part of the view-model:

self.amountToday = ko.computed({
        read: function () {
            if (self.departments().length > 0) {
                return self.departments()[0].saleAmountToday();
            }
        },
        write: function (value) {
            //nothing
        },
        owner: self
    });

and here is the description call in jqxchart:

description: amountToday()

Hi merseysider85,

The description property of jqxChart is not observable so it cannot be bound with KO. If you change that property by code, make sure to call the jqxChart’s “refresh” method after to update the description.
