C1Gallery supports retrieving data (nodes) dynamically. Child items are loaded using AJAX when they are scrolled into view. In the examples below you'll enable loading data on demand by setting the LoadOnDemand property to True.

In Source View

In Source view add LoadOnDemand="True" to the <cc1:C1Gallery> tag so it appears similar to the following:

<cc1:C1Gallery ID="C1Gallery1" runat="server" LoadOnDemand="True">

At Design Time

In Design view, select the C1Gallery control and in the Properties window set the LoadOnDemand property to True.

In Code

Add the following code to the Page_Load event:

To write code in Visual Basic

Me.C1Gallery1.LoadOnDemand = True                                        

To write code in C#

this.C1Gallery1.LoadOnDemand = true;
