[CLOSED] After doing a 'Store1.DataBind()' how could I find the count of how many items are in the Store ???

[Fahd]

The syntax has change from the last version I was using which was v1.4

Or even finding out the items in the Grid that Store1 is binded too ??

Hi,

Please provide more details.

It would be best to call the GetCount or Length of the object which you apply to the Store DataSource.

Thats the issue, when I call the Store1.DataBind(), it calls a Handler which I setup in the Page Load like this:

                   Store1.Proxy.Add(new AjaxProxy
                    {
                        NoCache = true,
                        Json = true,
                        ActionMethods = { Read = HttpMethod.GET },
                        Reader = { new JsonReader { Root = "Data", TotalProperty = "TotalRecords" } },
                        Url = Core.Web.ProcessController.GetHandlerUrl()
                    });

and my handler then return this:

        context.Response.Write(JSON.Serialize(list));

So I don't have an object to that DataSource.

If the Store is configured with the Proxy please call

store.LoadProxy();

to initiate a load request.

And there is no way to get the count of loaded records just after the LoadProxy calling, because they are loaded asynchronously via AJAX since you have set up the AjaxProxy.

You could get the count of records client side setting up a callback.

Example

JFunction fn = new JFunction()
{
    Handler = "alert(records.length);",
    Args = new string[] { "records", "operation", "success" }
};
Store store = this.GridPanel1.GetStore();
store.LoadProxy(new
{
    callback = fn
});

Ok, let me give it a shot, I have never implemented a callback function before...

Leave this tread open, I'll get back to you.

Thanks for pointing me in the right direction.
