member ContentTemplate : ITemplate with get, set

Property Value

Type: System.Web.UI.ITemplate

An ITemplate instance that defines the content of the UpdatePanel control. The default is null.

Exception Condition
InvalidOperationException

The ContentTemplate property of the UpdatePanel control is set after an instance of the template is created or after the content template container is created.

The ContentTemplate property contains the content that appears inside an UpdatePanel control when it is rendered. You can create the template's content declaratively or programmatically. The content template of an UpdatePanel control is a single-instance template. Therefore, the properties of the controls it contains can be accessed directly on the page without using the FindControl method. For more information, see the TemplateInstanceAttribute class overview.

To add items to the UpdatePanel control declaratively, add an <ContentTemplate> element between the opening and closing tags of the UpdatePanel control. Inside the <ContentTemplate> element tags, declare other controls and HTML elements.

To add items to the UpdatePanel control dynamically, use the ContentTemplateContainer property, which enables you to add child controls without having to create a custom template that implements the ITemplate interface.
