[CLOSED] How to make sync call using Ajaxproxy (Store)

[SaurabhGuptaNiit]

Hi,
I have created a store with Ajaxproxy.
Its working fine as it make the async call but as per our requirement I need to change it sync call.

 var storePositionBreakTarget = Html.X().Store().ID("UC085_LinearBreakTargets_Store_PositionBreakTarget").AutoLoad(true) 
        .Model(Html.X().Model()
            .Fields(
             new ModelField("Key", ModelFieldType.String),
             new ModelField("Name", ModelFieldType.String)
            )
         )
          .Proxy(Html.X().AjaxProxy()
                
                 .Url(Url.Action("../LinearBreakTargets/FindBreakPositionCombination"))
               
                 .Reader(Html.X().JsonReader().Root("data"))
         ).Listeners(L => L.Load.Fn = "ManageLBT.createPositionBreakType");

Help will be appreciated

Thanks

Can you define what you mean by "sync" call? I'm not sure your definition of sync and our definition of sync would be the same.

Thanks for the reply,

Synchronous means that code execution will block (or wait) for the API call to return before continuing.
as we have option to make it sync in JS need to implement same in ext.net

 Ext.create('Ext.data.Store', {
        id:'optionsStore',
        autoLoad: true,
        model: 'Options',
        async : false,
        proxy: {
            type: 'ajax',
            async : false,
            url: base_url+'dna2/form/get_options',  // url that will load data with respect to start and limit params
            noCache: false,
            reader: {
                async:false,
                type: 'json',
                root: 'rows',
                totalProperty: 'totalCount'
            }
            
        }  
    });

Hi @SaurabhGuptaNiit,

I can suggest this solution:

proxy: {
    type: "ajax",
    buildRequest: Ext.Function.createSequence(Ext.data.proxy.Ajax.prototype.buildRequest, function (operation) {
        operation.request.async = false;
        return operation.request;
    }),
    ...
}

Can you provide more information about why a sync request is required and why an async one cannot be used?
Sync requests is a bad practice and it should not be used in my opinion.

Note: Starting with Gecko 30.0 (Firefox 30.0 / Thunderbird 30.0 / SeaMonkey 2.27), synchronous requests on the main thread have been deprecated due to the negative effects to the user experience.
