List Binding Multiple Times

[Scott Rakestraw]

I have a dropdownlist which is bound to a shared kendo datasource.  The shared datasource has already read it's data in.  When I am binding it to this drop down it is calling read on this dataset again.  If I create ddl without the data-bind it will not attempt to read the data a 2nd time.  How do I prevent the dropdownlist from forcing the datasource to read the data?

var ddl = $('<input data-bind="value:' + options.field + '" style="display:none;"/>')
            .appendTo(container);

ddl.kendoDropDownList({
    dataTextField: list.displayColumn,
    dataValueField: list.valueColumn,
    autoBind: false,
    optionLabel: optionLabel,
    dataSource: list.dataSource
});

I have the same problem, did you find a solution?

Hi guys,

To avoid the additional read request, please set the autoBind option of the widget to false.

data-auto-bind="false"

I have changed the code

var ddl = $('<input data-bind="value:' + options.field + '" style="display:none;" data-auto-bind="false" />').appendTo(container);

The same problem still exists.  It is forcing a second call to get the data.  When creating the drop down I had already specified autoBind false there.  It is now set in both places.

Hi Scott,

I prepared a small sample to test the solution - I checked the network tab and did not manage to observe any additional requests. Could you please check it and let me know what I am missing?

I found my problem.  I was doing a basic pub/sub so that the list could build itself after the data was returned in the schema data function.  I needed to change that publish event to run inside a setTimeout so it would run after the datasource was filled.
