Public method Focus Sets input focus to a control.
Protected method GetDesignModeState Infrastructure. Gets design-time data for a control.
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetType Gets the type of the current instance. (Inherited from Object.)
Public method HasControls Determines if the server control contains any child controls.
Protected method HasEvents Returns a value indicating whether events are registered for the control or any child controls.

Protected method LoadControlState Restores control-state information from a previous page request that was saved by the SaveControlState method.
Protected method LoadViewState Restores view-state information from a previous page request that was saved by the SaveViewState method.
Protected method MapPathSecure Retrieves the physical path that a virtual path, either absolute or relative, maps to.
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Protected method OnBubbleEvent Determines whether the event for the server control is passed up the page's UI server control hierarchy.
Protected method OnDataBinding Raises the DataBinding event.
Protected method OnInit Raises the Init event.
Protected method OnLoad Raises the Load event.
Protected method OnPreRender Raises the PreRender event.
Protected method OnUnload Raises the Unload event.
Protected method OpenFile Gets a Stream used to read a file.
Protected method RaiseBubbleEvent Assigns any sources of the event and its information to the control's parent.
Protected method RemovedControl Called after a child control is removed from the Controls collection of the Control object.
Protected method Render Sends server control content to a provided HtmlTextWriter object, which writes the content to be rendered on the client.
Protected method RenderChildren Outputs the content of a server control's children to a provided HtmlTextWriter object, which writes the content to be rendered on the client.
Public method RenderControl Overloaded. Outputs server control content and stores tracing information about the control if tracing is enabled.
Protected method ResolveAdapter Gets the control adapter responsible for rendering the specified control.
Public method ResolveClientUrl Gets a URL that can be used by the browser.
Public method ResolveUrl Converts a URL into one that is usable on the requesting client.
Protected method SaveControlState Saves any server control state changes that have occurred since the time the page was posted back to the server.
Protected method SaveViewState Saves any server control view-state changes that have occurred since the time the page was posted back to the server.
Protected method SetDesignModeState Sets design-time data for a control.
Public method SetRenderMethodDelegate Infrastructure. Assigns an event handler delegate to render the server control and its content into its parent control.
Public method ToString Returns a string that represents the current object. (Inherited from Object.)
Protected method TrackViewState Causes tracking of view-state changes to the server control so they can be stored in the server control's StateBag object. This object is accessible through the Control.ViewState property.
