XML Provider

This help article describes how you can bind the RadGantt control to an XML file using the built-in XmlGanttProvider.

Binding the control to a XML file is achievable by following the below listed steps.

1. Add the XML containing the data in the App_Data folder.

2. Subscribe to the PageLoad event and in the event handler create a new instance of the XmlGanttProvider provider passing the XML file path to its constructor.

3. Set the RadGantt.Provider property to the newly created provider instance.

The below provided example illustrates a possible realization of the above mentioned.

ASPNET

<telerik:RadGantt RenderMode="Lightweight" ID="RadGantt1" runat="server" >
</telerik:RadGantt>

C#

protected void Page_Load(object sender, EventArgs e)
{
    RadGantt1.Provider = new XmlGanttProvider(Server.MapPath("App_Code/Gantt.xml"));
}

VB.NET

Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
    RadGantt1.Provider = New XmlGanttProvider(Server.MapPath("App_Code/Gantt.xml"))
End Sub

The format of the XML file that contains the data should look similar to the below shown.

If the XML file will be initially blank it should contain a Project opening and closing tag.
