Instead of traditional ASP.NET AJAX approach for "Exposing Web Services to Client Script" you can use jQuery and JSON2 JavaScript libraries to achieve the same very easily.

Using this simple method you can call any page method in ASP.NET Page or WebService method:

function executeMethod(location, methodName, methodArguments, onSuccess, onFail) {
    $.ajax({
        type: "POST",
        url: location + "/" + methodName,
        data: methodArguments,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: onSuccess,
        fail: onFail
    });
}

Here is an example also how to use JSON2 JavaScript library to serialize any JavaScript object to string:

function getRequestData(tableView) {
    return JSON.stringify({...

I've made yet another ASP.NET MVC example with RadGrid for ASP.NET AJAX however instead of Html.Form and Html.ActionLink I have used Ajax.Form and Ajax.ActionLink:

As a result now you have an ajax enabled grid with paging, sorting, select, edit, update, delete and insert:

To continue with my previous blog post about RadGrid for ASP.NET AJAX in Microsoft ASP.NET MVC, I've made another example how to use RadControls for ASP.NET AJAX as pure client-side components in this environment. The biggest challenge here is the ScriptManager and scripts registration in general. By default the creation of client-side components is so tightly coupled with the ajax functionality (PageRequestManager) that the only way to enable this is to inherit from ScriptManager (or RadScriptManager) and build everything manually:

protected override void Render(HtmlTextWriter writer)
{
     foreach (RegisteredScript script in GetRegisteredClientScriptBlocks())
     {
         if (Page.Items[script.Key] == null)
         {
             Page.Items[script.Key] =...

I've made small example how to use RadGrid for ASP.NET AJAX in Microsoft ASP.NET MVC:

The key here is to inherit from RadGrid and call explicitly desired grid commands. Let's say you want to edit particular record:

1) Create a template column and add this to the ItemTemplate:

<%# Html.ActionLink("Edit", "RadGridCommand", new { ControlID = MyGrid1.ID, CommandName = "Edit", CommandArgument = Container.ItemIndexHierarchical }) %>

2) Now handle this in your controller:

public ActionResult RadGridCommand(string ControlID, string CommandName, string CommandArgument)
{
    ViewData["ControlID"] = ControlID;
    ViewData["CommandName"]= CommandName;
    ViewData["CommandArgument"] = CommandArgument;

    return View("Index");
}

3) Override OnPreRender in inherited class and call explicitly the grid...

Yesterday I saw this and I really liked the script. The idea is to animate backgroundPosition CSS property for desired HTML element and I have created small example how to do the same for RadGrid column headers:

Enjoy!

My new example illustrates how to cache the grid data client-side based on the current grid state. To do this we need to build a state key using current page index, page size, sort expressions and filter expressions:

Every time when we get new data we can store the result in our client-side cache:

and when the next grid command occur we can call explicitly updateGrid() method if we have already saved result for the current grid...

In continue to my previous posts related to RadGrid for ASP.NET AJAX client-side data-binding, I've created new example how to bind the grid to a WCF service:

web.config service registration:

<system.serviceModel> 
    <behaviors> 
        <serviceBehaviors> 
            <behavior name="ServiceBehavior">  
                <serviceMetadata httpGetEnabled="true"/>  
                <serviceDebug includeExceptionDetailInFaults="false"/>...

I've made two Master/Detail demos using RadGrid for ASP.NET AJAX, LINQ to SQL and WebService client-side data-binding.

The first example is a single grid with two hierarchical levels (Customers -> Orders) with enabled paging, sorting & filtering for the entire hierarchy:

and the second demo is a classic Master/Detail with two grids:

Today I saw this blog post and I couldn't resist to test RadGridView for WPF using the same data :)

Looks like by default our grid will sort approximately 10 times faster - no need to build your own custom comparers.

Enjoy!

I'm pleased to announce that the next version of RadGrid for ASP.NET AJAX will support natively EntityDataSource.
All operations like paging, sorting and filtering will be applied directly on the data-base server:

and of course you will able to insert, update and delete records completely codeless.

Enjoy!
