Below is the output of your code. It has a form and respective validation controls along with a validation summary control.
You have successfully learned the ASP. This property is used primarily by control developers. Gets the virtual directory of the Page or UserControl that contains the current server control.
Gets or sets a value that indicates whether the control checks client input from the browser for potentially dangerous values. Gets or sets the group of controls for which the ValidationSummary object displays validation messages. Gets a dictionary of state information that allows you to save and restore the view state of a server control across multiple requests for the same page.
Gets a value that indicates whether the StateBag object is case-insensitive. Called after a child control is added to the Controls collection of the Control object. Copies any nonblank elements of the specified style to the Web control, overwriting any existing style elements of the control. This method is primarily used by control developers.
Gathers information about the server control and delivers it to the Trace property to be displayed when tracing is enabled for the page. Sets the cached ClientID value to null. Deletes the view-state and control-state information for all the server control's child controls.
Copies the properties not encapsulated by the Style object from the specified Web server control to the Web server control that this method is called from. This method is used primarily by control developers. Called by the ASP. NET page framework to notify server controls that use composition-based implementation to create any child controls they contain in preparation for posting back or rendering. Creates a new ControlCollection object to hold the child controls both literal and server of the server control.
Creates the style object that is used internally by the WebControl class to implement all style related properties. Binds a data source to the invoked server control and all its child controls with an option to raise the DataBinding event. Determines whether the server control contains child controls. If it does not, it creates child controls.
Searches the current naming container for a server control with the specified id parameter. Searches the current naming container for a server control with the specified id and an integer, specified in the pathOffset parameter, which aids in the search.
You should not override this version of the FindControl method. Gets the Type of the current instance. Returns the prefixed portion of the UniqueID property of the specified control. Restores control-state information from a previous page request that was saved by the SaveControlState method. Restores view-state information from a previous request that was saved with the SaveViewState method. Creates a shallow copy of the current Object.
Copies any nonblank elements of the specified style to the Web control, but will not overwrite any existing style elements of the control.
Determines whether the event for the server control is passed up the page's UI server control hierarchy. Raises the DataBinding event. Raises the Init event. Raises the Load event. Raises the PreRender event. Raises the Unload event. Gets a Stream used to read a file.
Called after a child control is removed from the Controls collection of the Control object. Sends server control content to a provided HtmlTextWriter object, which writes the content to be rendered on the client. Renders the HTML opening tag of the control to the specified writer. Outputs the content of a server control's children to a provided HtmlTextWriter object, which writes the content to be rendered on the client. Renders the contents of the control to the specified writer.
Outputs server control content to a provided HtmlTextWriter object and stores tracing information about the control if tracing is enabled. Outputs server control content to a provided HtmlTextWriter object using a provided ControlAdapter object.
Renders the HTML closing tag of the control into the specified writer. Saves any server control state changes that have occurred since the time the page was posted back to the server. Saves any state that was modified after the TrackViewState method was invoked. Assigns an event handler delegate to render the server control and its content into its parent control. Sets trace data for design-time tracing of rendering data, using the trace data key and the trace data value.
Sets trace data for design-time tracing of rendering data, using the traced object, the trace data key, and the trace data value. Causes the control to track changes to its view state so they can be stored in the object's ViewState property. Occurs when a server control is released from memory, which is the last stage of the server control lifecycle when an ASP.
NET page is requested. Occurs when the server control is loaded into the Page object. Occurs after the Control object is loaded but prior to rendering. For a description of this member, see ControlBuilder. For a description of this member, see GetDesignModeState.

Note When you use the ValidationSummary control inside an UpdatePanel control, make sure that the validator control and the control it is associated with are in the same panel. The ValidationSummary extension method displays a summary of all validation errors on a web page as an unordered list element.
It can also be used to display custom error messages. The ValidationMessageFor displays an error message for an individual field, whereas the ValidationSummary displays all the error messages. Consider the following Student model class with the Required and Range validation attributes. The following view uses the ValidationSummary method to display all the error messages.
Above, the first parameter of the ValidationSummary is false, so it will display the field level errors as a summary. The second parameter is for the message.
