Web Service Binding

This help article demonstrates how easy is to create a Web Service and bind RadGantt to it using the WebServiceController and one of the RadGantt's providers

The following example demonstrates the signature of the web service and how the WebServiceController is used for handling all WebMethods. In this particular example, an XmlGanttProvider is used for providing the data from an XML file:

/// <summary>
/// Summary description for GanttService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.Web.Script.Services.ScriptService]
public class GanttService : System.Web.Services.WebService
{

    private WebServiceController _controller;

    public WebServiceController Controller
    {
        get
        {
            if (_controller == null)
            {
                _controller = new WebServiceController(new XmlGanttProvider(Server.MapPath("~/App_Data/Tasks.xml"), true));
            }

            return _controller;
        }
    }

    [WebMethod]
    public IEnumerable<TaskData> GetTasks()
    {
        return Controller.GetTasks();
    }

    [WebMethod]
    public IEnumerable<TaskData> InsertTasks(IEnumerable<TaskData> models)
    {
        return Controller.InsertTasks(models);
    }

    [WebMethod]
    public IEnumerable<TaskData> UpdateTasks(IEnumerable<TaskData> models)
    {
        return Controller.UpdateTasks(models);
    }

    [WebMethod]
    public IEnumerable<TaskData> DeleteTasks(IEnumerable<TaskData> models)
    {
        return Controller.DeleteTasks(models);
    }

    [WebMethod]
    public IEnumerable<DependencyData> GetDependencies()
    {
        return Controller.GetDependencies();
    }

    [WebMethod]
    public IEnumerable<DependencyData> InsertDependencies(IEnumerable<DependencyData> models)
    {
        return Controller.InsertDependencies(models);
    }

    [WebMethod]
    public IEnumerable<DependencyData> DeleteDependencies(IEnumerable<DependencyData> models)
    {
        return Controller.DeleteDependencies(models);
    }
}   
<WebMethod(EnableSession:=True)> _
Public Function GetResources() As IEnumerable(Of Telerik.Web.UI.Gantt.ResourceData)
    Return Controller.GetResources()
End Function

<WebMethod(EnableSession:=True)> _
Public Function GetAssignments() As IEnumerable(Of AssignmentData)
    Return Controller.GetAssignments()
End Function

<WebMethod(EnableSession:=True)> _
Public Function InsertAssignments(models As IEnumerable(Of AssignmentData)) As IEnumerable(Of AssignmentData)
    Return Controller.InsertAssignments(models)
End Function

<WebMethod(EnableSession:=True)> _
Public Function DeleteAssignments(models As IEnumerable(Of AssignmentData)) As IEnumerable(Of AssignmentData)
    Return Controller.DeleteAssignments(models)
End Function

And bellow are the settings needed for binding RadGantt to the above web service:

<telerik:RadGantt RenderMode="Lightweight" runat="server" ID="RadGantt1">
    <WebServiceSettings Path="GanttService.asmx" />
</telerik:RadGantt>
