Store proxy calling asp.net asmx webservice

[lrobins]

The following code works to call a .net webservice

Ext.Ajax.request({
            headers: {
                'Content-Type': 'application/json; charset=utf-8'
            },
            method: 'POST',
            url: 'Services.asmx/MyWebservice',
            success: function (response) {
                //load my store with json formatted data returned in response.responseText
            }
        });

The following code uses a store proxy to call the same .net webservice, but does not work

var theStore = Ext.create('Ext.data.Store', {
            model: 'App.model.RequestNotesItem',           
            proxy: {
                type: 'ajax',
                url: 'Services.asmx/MyWebService',
                headers: {
                    'Content-Type': 'application/json; charset=utf-8'
                },
                actionMethods: {
                    create: 'POST',
                    read: 'POST',
                    update: 'POST',
                    destroy: 'POST'
                }
            }
        });
        theStore.load();

Does anyone have experience/success in calling an asp.net webservice using the proxy on a store?

What does the JSON look like? Do you need to configure the reader?

[lrobins]

I had to add these to the proxy to make it return json successfully

reader: {
         type: 'json',
         root: 'd'
},
writer: {
        encodeRequest: true,
        type: 'json'
}

Here is a sample of the json returned.

{"d":"[{\"note_id\":165,\"added_date\":\"2/16/2012 5:03:16 PM\",\"added_by_name\":\"Person1\",\"note_text\":\"and yet another\"},{\"note_id\":164,\"added_date\":\"2/16/2012 5:01:42 PM\",\"added_by_name\":\"Person2\",\"note_text\":\"aabc dd eff lorem ipsum\"}]"}

.net wraps it in a "d" for security reasons.

**UPDATE**
This thread got mistakenly marked as answered, but it's not answered. I wasn't sure how to set it back. I'm getting a json response, but it isn't loading the store correctly.

I found my problem. The asp.net asmx service I was using to return json was returning a json string. So it looks like the proxy reader cannot read that json string. I changed to a asp.net wcf service and return a json object through a Stream instead of returning a string (found a bunch of examples of this on google). The store loads the data correctly this way. Hope this helps some fellow asp.net people.
