2.0 BETA ExtraParam added in codebehind not being added to service call

[craigymcm]

Hi,

I'm developing a small webpage but when i try to add an extra parameter to a JSON proxy from code behind it doesn't seem to update the parameter in the request.

Can someone offer me any insight?

//Get Json Postback Values and put in string
            String JsonRequest = e.ExtraParams["Values"];

            //Deserialize String And Put values into instance of object
            JavaScriptSerializer serializer = new JavaScriptSerializer();
            IList<SiteVisit> SiteVisits = new JavaScriptSerializer().Deserialize<IList<SiteVisit>>(JsonRequest);

            //Build New Store Parameter
            var StoreParam = new Ext.Net.StoreParameter("VisitorID", SiteVisits[0].VisitorID.ToString(), ParameterMode.Value, false);


            //Set instance of Store that you want to ammend
            var store = this.PreviousVisitsTabPanel.GetStore();
            
            //Add pre-generated Parameter To Store
            store.Parameters.Add(StoreParam);
            //Bind Changes To Store
            store.DataBind();
            //Show tab panel
            this.PreviousVisitsTabPanel.Show();
            //Reload store
            store.Reload();

I thought i better make this clearer:

The Parameter i'm adding to the store

//Build New Store Parameter
            var StoreParam = new Ext.Net.StoreParameter("VisitorID", SiteVisits[0].VisitorID.ToString(), ParameterMode.Value, false);

JSON Similar to {"VisitorID":"665frreerr"}

Is not being added to the web service request after the store.reload()

If someone could tell me where I'm going wrong it would be greatly appreciated.

Sorry to bump this again guys but really struggling here.

Upon inspection of locals I'm getting a message about changes not being committed?

Can anyone help shed any light on this...

[craigymcm]

Really am struggeling, can anyone confirm if this is a beta only related issue?

Hi,

We're investigating this thread/request right now and should have a response for you shortly.

Params cannot be updated after store creation (client side creation) but you can pass new params to reload method

Store1.Reload(new {@params = new {VisitorID = "NewVisitorID"}});

It also could look like this:

Ext.Net.ParameterCollection ps = new Ext.Net.ParameterCollection();
ps.Add(new Ext.Net.Parameter("test", DateTime.Now.Second.ToString(), ParameterMode.Value));
        
Store1.Reload(new
{
    @params = ps.ToJson()
});

I think we should consider to implement the following overloaded Reload method:

Store.Reload(new Ext.Net.ParameterCollection());

ps.Add(new Ext.Net.Parameter("test", DateTime.Now.Second.ToString(), ParameterMode.Value));

{
    @params = ps.ToJson()

Store.Reload(new Ext.Net.ParameterCollection());

I've adapted the code you supplied above to add new parameters to the store but unfortunately no parameters are being requested in the web service call...

This is the JSON returned by the Direct Event:

{script:"App.PreviousVisitsTabPanel.setTitle(\"Previous Visits (Visitor ID: 6DED659CEC752F01)\");App.PreviousVisitsTabPanel.show();App.PreviousVisitsStore.reload({\"params\":\"{\\\"VisitorID\\\":\\\"6DED659CEC752F01\\\"}\"});"}

But the parameter is still not being called in either the query string or being passed as a posted parameter:

"previousvisits.php?_dc=1338218812660&callback=Ext .data.JsonP.callback4"

[Daniil]

Please try:

@params = JRawValue.From(ps.ToJson())

instead of

@params = ps.ToJson()

[craigymcm]

Please try:

@params = JRawValue.From(ps.ToJson())

instead of

@params = ps.ToJson()

Completely worked a treat....
