Add an Activity on the Server

In server-side code, you can add a new Activity to the Activities collection of the WebScheduleInfo™ after data binding to render that appointment for the current page request. Because your intention is only to render this activity, the PreRender event of the Page class is the best place to put it.

Note

Note:

The Activities collection is never preserved in ViewState (even when ViewState is enabled) by design because of its redundancy with the data store. On each page request, the WebScheduleInfo re-binds to that data store. If you want to add this activity programmatically to the data store, see How to Add an Activity to the Database.

If you do not see the Activity you have added, verify that you have called the DataBind method on WebScheduleInfo before adding the Activity. Data binding clears the Activities collection in order to fill it with current scheduling information from the data store.

To add an Appointment , you must call the Add method on the Activities collection with this newly initialized Activity after data binding.

In Visual Basic:

Imports Infragistics.WebUI.Shared
Imports Infragistics.WebUI.WebSchedule
...
Private Sub Page_PreRender(ByVal sender As Object, _
	ByVal e As EventArgs) Handles MyBase.PreRender
	'Data-bind manually before adding Activities to the collection.
	Me.WebScheduleInfo1.DataBind()
	'Create and initialize an Activity through my helper function.
	Dim appt As Appointment = Me.CreateAppointment()
	'Add Activity to the Activities collection on WebScheduleInfo1.
	Me.WebScheduleInfo1.Activities.Add(appt)
End Sub

In C#:

using Infragistics.WebUI.Shared;
using Infragistics.WebUI.WebSchedule;
...
private void Page_PreRender(object sender, EventArgs e)
{
	// Data-bind manually before adding Activities to the collection.
	this.WebScheduleInfo1.DataBind();
	// Create and initialize an Activity through my helper function.
	Appointment appt = this.CreateAppointment();
	// Add Activity to the Activities collection on WebScheduleInfo1.
	this.WebScheduleInfo1.Activities.Add(appt);
}
