This example demonstrates how to implement date range filtering in the GridView extension.
Use the MVCxGridViewColumn.SetFilterTemplateContent method to create a custom editor and assign a delegate method to the GridViewSettings.ProcessColumnAutoFilter property to process a custom filter expression sent from the client side.

GridView - How to use the jQuery autocomplete plugin with ASP.NET WebApi
The Autocomplete plugin allows you to implement the functionality that helps end-users find and select values from a pre-populated list while typing. It also allows loading this list on demand by using AJAX requests to a remote service, which reduces the page rendering time.
ASP.NET Web API is a framework that makes it easy to build HTTP services that reach a broad range of clients, including browsers and mobile devices. ASP.NET Web API is an ideal platform for building RESTful applications in the .NET Framework.
This example demonstrates how to combine these features for the GridView's EditForm editor.
Main points are:
1) Add a WebApi Controller to the Controllers folder and define a method that returns a portion of data depending on the typed text;
2) Register a WebApi route as it described in the Routing in ASP.NET Web APIarticle;
3) Add references to the jQuery and jQuery UI libraries;
4) Handle the client-side Init event for the corresponding editor;
Now it is possible to implement the autocomplete functionality. When the end-user types text into the "FirstName", the text is obtained from the editor and assigned to Autocomplete's select attribute. Then an AJAX request is sent to the server and calls the corresponding method in WebApi. The result of the request is returned to the client and used for Autocomplete's source attribute.

End-User Restrictions - How to define "availability" intervals for different resources
This example illustrates how to define different time intervals that are available for scheduling. This information is stored in the ~\App_Data\ResourcesAvailabilities.mdb database. It has the ResourcesAvailabilities table with the following schema:
Id: Integer,
ResourceId: String,
StartTime: DateTime,
EndTime: DateTime
So, generally, each resource can have independent availability intervals. This information is loaded and exposed via the ResourcesAvailabilities class.
First of all, we use this information to modify the default appearance of the Time Cells by handling the ASPxScheduler.HtmlTimeCellPrepared Event. Then, we disallow appointment creation and modification actions if their execution is initiated outside available intervals. For this, we substitute the regular MenuViewCallbackCommand with a custom one (see Callback Commands), and handle the ASPxScheduler.AppointmentChanging Event. Note that we use a technique from the How to show user friendly message from the server on a callback ticket to show a warning if the end-user tries to schedule an appointment in the restricted area. In other words, we handle the ASPxScheduler.CustomJSProperties Event on the server side to pass a warning message on the client side. This message is intercepted in the ASPxClientScheduler.EndCallback Event.
Here is a screenshot that illustrates a sample application in action:

How to print ASPxScheduler via the XtraSchedulerReport on a separate web page
This example illustrates how to print ASPxScheduler on a separate web page. For this an invisible ASPxScheduler is placed to this web page (ReportingPage.aspx). This is the simplest method to connect the XtraSchedulerReport to the underlying data (appointments and resources). Note also that you can avoid using invisible ASPxScheduler. This approach is demonstrated in the Can you generate a XtraSchedulerReport preview/print without having an ASPxScheduler control? thread.

How to filter appointments by custom field values
This example illustrates how to filter appointments by custom field values. A particular value is selected via the ASPxComboBox. In the ASPxClientComboBox.SelectedIndexChanged event handler this value is stored in the HiddenField and the scheduler is refreshed via the ASPxClientScheduler.Refresh() method. Then, on the server side, the ASPxScheduler.FilterAppointment event handler is fired. The value from the HiddenField is used to filter appointments.

Runtime detail height sizing with respect to XRSubreport size
In a single detail band an XRLabel and XRSubreport are placed side-by-side. The goal is to resize the XRLabel height to match the accompanying XRSubreport. This may be accomplished by calling CreateDocument twice. The first call sums the brick height of each subreport section and adds this float value to the dictionary under its category key. On the second CreateDocument call, the DetailBand.BeforePrint handler resizes each detail from the section sizes in the dictionary.

I added the jquery ui resize and drag properties to the div around the charting component. However when the div is resized, the svg chart is not resized, it stays orphaned from the parent div control.
How do I set 'id' to the SVG or set the width and height of the SVG to be 100% so that when I resize the parent div control, even the svg is resized accordingly.

Hello Sathish,
I have created a Support Center ticket on your behalf to discuss this issue: DXTREME - The Chart is not automatically resized. Please bear with us, we will answer your question as soon as possible.
Added By: david karasek at: 5/8/2013 8:47:06 AMWas this ever resolved? Is there a complete example and guide of inter-operability between DxTreme and and Dxperience? In an AJAX context, what is the best practice for these to work well together?
Wouldn't change events in the grid need to be triggered via AJAX so as not to do a full page refresh?
In addition what is the best process for this working in MVC? The same as ASP web forms? Different?
Hello David,
I have create a new ticket on your behald to discuss your questions: Few question about interaction between DevExpress ASP.NET components and DXTREME Mobile widgets?. Please bear with us, we will ge back to you as soon as possible.

How to apply theme to DevExpress ASP.NET Control Descendant
How to apply a theme to a DevExpress control descendant
To apply a theme to Custom Control that uses some of DevExpress controls you need to apply a global theme for the page or for the entire application. In order to do that, use the ThemeDeployer tool to copy necessary files to your project folder. Note that our controls may use other simple controls, for example ASPxComboBox. So it is a good idea to copy files for all the controls.
After that you need to add some code to the page's Init event handler:
[C#]formLayout.CssPostfix=this.Page.Theme;
The CssPostfix property is related only with DevExpress controls and cannot be used with standard ASP.NET controls.
