C#

public override sealed System.Web.UI.ControlCollection Controls { get; }

Property Value

ControlCollection

The collection of child controls for the UpdatePanel control.

Exceptions

InvalidOperationException

The Add(Control), AddAt(Int32, Control), Clear(), Remove(Control), or RemoveAt(Int32) method of the ControlCollection class has been called. To change the content of the UpdatePanel control, modify the child controls of the ContentTemplateContainer property.

Remarks

The Controls property is overridden from the base Control class and sealed to prevent additional derivation. To add controls to the UpdatePanel control declaratively, create a <ContentTemplate> element inside the UpdatePanel control markup. To add controls to the UpdatePanel control programmatically, use the ContentTemplateContainer property.
