To insert a new friend in database table called tblFileUpload. 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 for the FileUpload control. 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 the FileUpload control content to the specified HtmlTextWriter object, which writes the content to render 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.

We will then create a directory into the project to store uploaded files as we did in the below screenshot. It now displays a successful file uploaded message after uploading, as shown in the following screenshot. This file is stored in the upload folder. Look inside the folder, and it shows the uploaded file is present. NET FileUpload control provides AllowMultiple property for uploading multiple files to the server that takes either true or false value.
NET provides implicit object Response and their methods to download a file from the server. We can use these methods to add the feature of downloading a file from the server to the local machine.
