With DHTMLX Scheduler .NET you can create not solely a MVC-based calendar control but also get a ready simple ASP.NET calendar application/scheduling solution (WebForms):

Simply follow the 11 steps described below to get a simple ASP.NET calendar:

1. Create a new C# project by selecting ASP.NET Web Application;

2. Copy the library reference to your ‘App_Data’ project folder and go to References -> Add the reference to your application;

3. Copy the provided calendar scripts to the Scripts folder of your project;

4. Create a new database by right-clicking on ‘App_Data’ -> Add New Item -> Select SQL Sever Database and name it “Sample.mdf”;

5. Add a new table with the columns id, text, start_date and end_date. Data types should be set as int, nvarchar(250), datetime and datetime correspondingly (see the picture below). Save it as “Event”. Note that a primary key should be assigned to id and the identity column has to be additionally enabled;

The table can also be created with the following query:

CREATE TABLE [dbo].[Events]( [id] int IDENTITY(1,1) NOT NULL, [text] nvarchar(250) NULL, [start_date] datetime NOT NULL, [end_date] datetime NOT NULL, PRIMARY KEY (id) )

6. Right-click on ‘Your_project_name’ to create a new LINQ to SQL database model, name it “Sample.dbml” and add “Event” table to it;

7. To create the Scheduler object, go to “Default.aspx.cs” and configure your event calendar using a ‘Page_Load’ method (‘Page_Load’ is generated automatically when “Default.aspx” is created). To render the Scheduler from CodeBehind to the web-page, add a property to save data and assign the Scheduler object to the mentioned property:

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using DHTMLX.Scheduler; namespace mySchedulerNET { public partial class _Default : System.Web.UI.Page { public DHXScheduler Scheduler { get; set; } protected void Page_Load(object sender, EventArgs e) { this.Scheduler = new DHXScheduler(); } } }

Set the initial date and the recurrence pattern for your calendar events:

Scheduler.InitialDate = new DateTime(2011, 11, 24); Scheduler.Config.first_hour = 8; Scheduler.Config.last_hour = 19; Scheduler.Config.time_step = 30; Scheduler.Config.limit_time_select = true;

Define a route to load and save data:

Scheduler.DataAction = "Data.ashx"; Scheduler.SaveAction = "Save.ashx";

Enable data loading and processing, prevent cache:

Scheduler.LoadData = true; Scheduler.EnableDataprocessor = true;

The full code will look like this:

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using DHTMLX.Scheduler; namespace mySchedulerNET { public partial class _Default : System.Web.UI.Page { public DHXScheduler Scheduler { get; set; } protected void Page_Load(object sender, EventArgs e) { this.Scheduler = new DHXScheduler(); Scheduler.InitialDate = new DateTime(2011, 11, 24); Scheduler.Config.first_hour = 8; Scheduler.Config.last_hour = 19; Scheduler.Config.time_step = 30; Scheduler.Config.limit_time_select = true; Scheduler.DataAction = "Data.ashx"; Scheduler.SaveAction = "Save.ashx"; Scheduler.LoadData = true; Scheduler.EnableDataprocessor = true; } } }

8. Create “Default.aspx” to render your event calendar and set the initial size of the calendar container:

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="mySchedulerNET._Default" %> <asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"> </asp:Content> <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> <div style="height:509px; width: 100%;"> <%= this.Scheduler.Render()%> </div>

Override the default styles of the web-site. Set “0” padding to let the scheduler occupy the entire area of the application container:

<style> .main { padding: 0 !important; margin: 0 !important; } </style> </asp:Content>

The full code will look as follows:

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="mySchedulerNET._Default" %> <asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"> </asp:Content> <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> <div style="height:600px; width: 100%;"> <%= this.Scheduler.Render()%> </div> <style> .main { padding: 0 !important; margin: 0 !important; } </style> </asp:Content>

9. Right-click on “Your_project_name”, add a Generic Handler and name it “Data.ashx”. Connect the required namespaces where Scheduler is defined and change the content type to ‘json’ for data rendering:

using System; using System.Collections.Generic; using System.Linq; using System.Web; using DHTMLX.Scheduler.Data; namespace mySchedulerNET { public class Data : IHttpHandler { public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/json"; context.Response.Write( new SchedulerAjaxData(new SampleDataContext().Events).ToString() ); } public bool IsReusable { get { return false; } } } }

10. Add a Generic Handler “Save.ashx”. In the same way, connect the required namespaces; note that the content type should be ‘xml’ in this case.

using System; using System.Collections.Generic; using System.Linq; using System.Web; using DHTMLX.Common; namespace mySchedulerNET { public class Save : IHttpHandler { public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/xml"; var action = new DataAction(context.Request.Form); var data = new SampleDataContext();

In this application we use a helper ‘DHXEventsHelper’ to assembly the event object and update it in LINQ to SQL. Two methods - ‘Bind’ and ‘Update’ - are used for this purpose:

try { var changedEvent = (Event)DHXEventsHelper.Bind(typeof(Event), context.Request.Form);//create event object from request switch (action.Type) { case DataActionTypes.Insert: // define here your Insert logic data.Events.InsertOnSubmit(changedEvent); break; case DataActionTypes.Delete: // define here your Delete logic changedEvent = data.Events.SingleOrDefault(ev => ev.id == action.SourceId); data.Events.DeleteOnSubmit(changedEvent); break; default:// "update" // define here your Update logic var updated = data.Events.SingleOrDefault(ev => ev.id == action.SourceId); //update "updated" object by changedEvent's values, 'id' should remain unchanged DHXEventsHelper.Update(updated, changedEvent, new List<string>() { "id" }); break; }

Add ‘SumbitChanges’ value to submit data to the database and retrieve Event Id after the action is performed:

data.SubmitChanges(); action.TargetId = changedEvent.id;

Add ‘Error’ action type to mark action as failed in case of exception and render the response.

catch (Exception a) { action.Type = DataActionTypes.Error; } context.Response.Write(new AjaxSaveResponse(action).ToString());

} public bool IsReusable { get { return false; } } }

Here is the full code:

using System; using System.Collections.Generic; using System.Linq; using System.Web; using DHTMLX.Common; namespace mySchedulerNET { public class Save : IHttpHandler { public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/xml"; var action = new DataAction(context.Request.Form); var data = new SampleDataContext(); try { var changedEvent = (Event)DHXEventsHelper.Bind(typeof(Event), context.Request.Form);//create event object from request switch (action.Type) { case DataActionTypes.Insert: // define here your Insert logic data.Events.InsertOnSubmit(changedEvent); break; case DataActionTypes.Delete: // define here your Delete logic changedEvent = data.Events.SingleOrDefault(ev => ev.id == action.SourceId); data.Events.DeleteOnSubmit(changedEvent); break; default:// "update" // define here your Update logic var updated = data.Events.SingleOrDefault(ev => ev.id == action.SourceId); //update "updated" object by changedEvent's values, 'id' should remain unchanged DHXEventsHelper.Update(updated, changedEvent, new List<string>() { "id" }); break; } data.SubmitChanges(); action.TargetId = changedEvent.id; } catch (Exception a) { action.Type = DataActionTypes.Error; } context.Response.Write(new AjaxSaveResponse(action).ToString()); } public bool IsReusable { get { return false; } } } }

By following the above steps you'll get a basic .NET event calendar like this one:
