refresh (ajax binding)

[Shahar]

Hi,
I configured the Kendo MultiSelect for ajax binding, I send parameters to the server, All as described in
http://docs.kendoui.com/getting-started/using-kendo-with/aspnet-mvc/helpers/multiselect/overview#sending-parameters-to-the-server
Everything works fine except my call to the refresh method (http://docs.kendoui.com/api/web/multiselect).
The thing is that a new ajax request does not occur when I call refresh (is it by design? should I use another API?),
I need the List Of Values to be updated by a new Ajax call on change of another control.
The parameters I send to the server are

1. the text typed
2. a value of another control

Thanks in advanced,

Lauri

Hello Shachar,

The refresh method of the MultiSelect will redraw (re-render) the widget as described in the documentation. To perform re-fetch of the data from the server you should use the read method of the dataSource.

//if you have specified data function
//you just need to call the method like this
$('#myMultiSelect').data('kendoMultiSelect').dataSource.read();
//or you can send extra parameters like this
$('#myMultiSelect').data('kendoMultiSelect').dataSource.read({text:$('#someInput').val()});

Kind Regards,

Hello Petur Subev,

can I create a complete object instead if {text:$('#someInput').val()} to re-read. I need this functionality to reset the box to the state before changing. I store the dataSource and value and dataItems, but what can I do to reset the control?  

 My original question you will found here:

Kind regards,

Hello Oliver,

Hi,

I need Refresh data in multiselect after add new item in my database.
To the add new item send  in ajax JQuery and to the return in part the success i need refresh multiselect .

Could you tell me some way to do it?

Since in other components like the grid we can refresh it as something like this
  $ ( '# Multi'). Date ( 'kendoMultiselect'). Refresh ();

Hello Yazmin,

In general, the MultiSelect widget also has refresh method:

http://docs.telerik.com/kendo-ui/api/javascript/ui/multiselect#methods-refresh

This method will re-render the multiselect popup items, which will happen anyway if the source is updated. You can see how we add new items in the MultiSelect source here:

http://demos.telerik.com/kendo-ui/multiselect/addnewitem

As you can see once, the source is updated, the list is re-rendered.

Let me know if I am missing something.
