Integrating SignalR in HTML 5 Applications with Kendo UI – Webinar Resources

On Mar 12 2015 we conducted yet another webinar as part of our monthly webinar series. This time we were happy to invite Vidyasagar Machupalli who is a Microsoft MVP in Gaming. In fact he is the only Gaming MVP in South East Asia. The topic for this webinar was “Integrating SignalR in HTML5 Applications with Kendo UI”. Idea was to talk about real time communication in ASp.NET using SignalR and how Kendo UI makes it easy to work with SignalR.

ASP.NET SignalR:

Here is what the official description of SignalR is at

ASP.NET SignalR is a new library for ASP.NET developers that makes developing real-time web functionality easy. SignalR allows bi-directional communication between server and client. Servers can now push content to connected clients instantly as it becomes available. SignalR supports Web Sockets, and falls back to other compatible techniques for older browsers. SignalR includes APIs for connection management (for instance, connect and disconnect events), grouping connections, and authorization.

Kendo UI:

If you have been attending our webinars, you would have known about Kendo UI by now. If not, Kendo UI is a single package you need to develop HTML5 based sites/apps. Kendo UI is a HTML5 based client side JavaScript UI framework. To know more about Kendo UI head over to the project page here: You can find Kendo UI demos online here:




Q: Hi, SignalR is an advanced topic related to Web Sockets or Server Sent Events etc. Or it rely on these architecture?
A: SignalR is a real time communication technology on ASP.NET Stack from Microsoft.

Q: In order for the server to do real-time communication with SignalR, should the server be an IIS web server ?
A: SignalR at the moment can be hosted in IIS or as a stand alone process. But this requires you to be on Windows platform.

Q: Can we use Telerik controls with SignalR?
A: Absoutely. Telerik Kendo UI has specific binding/ support for SignalR.

Q: SignalR is purely async based or can it be set to be in sync mode like the way node.js is an async by default but can be set to mode sync?
A: SignalR is a server side technology and all it does is to keep track of all the clients connected and intimate them of any updates. So typically server sends a broadcast to all connected client and clients know how to react to this update on the client side.

Q: What is the most important advantage of SignalR ?
A: Real Time Communication between Server & Client.

RadHtmlChart LinqDataSource

How to bind LinqDataSource to RadHtmlChart for ASP.NET AJAX


RadHtmlChart which is a charting component in RadControls for ASP.NET AJAX suite supports binding to variety of data sources. In this post we will look at a scenario where we will see how to bind the RadHtmlChart to LinqDataSource. So the rest of this post is about how to achieve databinding linq data source to RadHtmlChatrt. So lets get started. First we will look at creating a new project in Visual Studio, then we will add a Data Context to the project, then add a LinqDataSource & use the data context to return top 10 products from Northwind database and finally add RadHtmlChart and see how to use LinqDataSource as the source of the chart.

Creating New Project:

To get started, let’s first create a new “C# RadControls Web Application”. Note you need to have our RadControls for ASP.NET suite installed before you can do this. Open a Visual Studio, select File > New Project > Telerik > Web and C# RadControls Web Application.

imageFigure 1: New Project Dialog

Visual Studio will go ahead and create a Web Application. It will have a single page named Default.aspx. For the rest of the demo, we will work with this page.

Add Northwind Data Context:

In order to work with Linq Data Source, I will create a Entity Data Context using our OpenAccess ORM. OpenAccess is a free tool to download and you can use this in your production too without any licensing involved. First Add New Item to your project of type “Telerik OpenAccess Domain Model”. Give it a name and click Ok.


Figure 2: Add New Item dialog

You will next be presented with a wizard. Here is the wizard dialog screen shots and the settings I have done:


Figure 3: OpenAccess Model Type


Figure 4: Database Connection


Figure 5: Database Items – Products Table Selected

SNAGHTML20dafe38Figure 6: Naming Rules


Figure 7: Code Generation Settings

Once you click finish, the wizard will create a .rlinq file in your project. If you double click the rlinq file, you will get a visual designer. For this post I have selected only Products table. So you will see the products table visually laid out:


Figure 8: OpenAccess Data Model

Next we will see how to add a LinqDataSource and hook that with our data model to return the products data.

Add LinqDataSource:

In order to add LinqDataSource to your page, you can either drag and drop from the tool box or directly code the tag in the source file. What we will do for this demo is, we will handle a specific event called OnSelecting. In the event handler we will instantiate our OpenAccess data model and return the top 10 products ordered by UnitPrice in descending order. Here is the code which defines LinqDataSource control on the page:

<asp:LinqDataSource ID="LinqDataSource1"

Here is the event handler definition:

protected void LinqDataSource1_Selecting(object sender, LinqDataSourceSelectEventArgs e)
        NorthwindDataModel context = new NorthwindDataModel();
        e.Result = context.Products
                          .OrderByDescending(p => p.UnitPrice)

Now that we have the data model and the linq data source only thing left out is to add the RadHtmlChart and bind it to linq data source.

Add RadHtmlChart:

So now we are ready to add the chart. You can either drag & drop the chart from the toolbox on to the page or code the chart definition directly on the page. In this post I will just add the RadHtmlChart code and highlight the main points you need to take care while wiring it with LinqDataSource.

So here is my chart definition:

<telerik:RadHtmlChart runat="server" ID="RadHtmlChart1"
                DataSourceID="LinqDataSource1" Width="1000" Height="700">
                        <telerik:ColumnSeries DataFieldY="UnitPrice" Name="Price">
                                <TextStyle Bold="true" FontSize="15" Color="Orange" />
                            <TooltipsAppearance Visible="false" />
                    <XAxis DataLabelsField="ProductName">
                        <LabelsAppearance RotationAngle="90" />
                        <MajorGridLines Visible="false" />
                        <MinorGridLines Visible="false" />
                        <LabelsAppearance><TextStyle Bold="true" /></LabelsAppearance>
                        <TitleAppearance Text="Units" />
                        <MinorGridLines Visible="false" />
                    <Appearance Visible="false" />
                <ChartTitle Text="Top 10 Products by Price">

Here are the things you need to do for wiring up the chart with LinqDataSource:

  • On the chart set the DataSourceID property to the ID of the LinqDataSource
  • When you define a series, set the DataFieldY property to a value “UnitPrice”. Here UnitPrice is the column in my data source which I want to bind and plot the points on Y axis
  • On the XAxis definition, set the DataLabelsField property to a value “ProductName”. Here ProductName is the column to which I want to bind and plot the XAxis points.

And that’s all its there to wiring up the RadHtmlChart to LinqDataSource. Now build the project and run to see the output. Here is a screenshot of the chart we just created:


Figure 9: RadHtmlChart output


In this blog post I wanted to show one of the data binding option that RadHtmlChart supports – namely LinqDataSource. As we have seen it is very easy to create a LinqDataSource and bind it to RadHtmlChart. We just need to take care of 3 things to make the chart work with the LinqDataSource. I hope this blog post gives you a head start if you are working with LinqDataSource and the RadHtmlChart. Do let us know your feedback/comment you may have on this post.

Till next time – Happy Coding.
