Resetting a winform’s elements to initialized state (C#/.Net)

I’m building a winform in C# with various elements in a panel that start out either invisible, disabled, or set to null (labels, combo boxes, grids, etc.). As the user goes through and makes choices, these elements are populated, selected, etc.

The idea is to upload files, read them, and process entries to a database. Once the processing for this directory has completed, I’d like to be able to have the user select another directory without exiting and restarting the winform app, by pressing a button that becomes visible when the process has completed.

Is there an easy call to reset the application (or the panel that contains the elements), similar to when a webform is refreshed, or do I have to write a function that “resets” all of those elements one at a time?

EDIT: As the result of a development meeting, my project has changed direction. I thank the two of you who helped with answers, and am going to close the question.

Method 1

Simple remove panel from the form and create the new one.

EDIT:
Sample:

Panel CreatePanelWithDynamicControls() {
    Panel ret = new Panel();
    ret.Dock = DockStyle.Fill;
    // some logic, which initialize content of panel

    return ret;
}

void InitializeDynamicControls() {
    this.Controls.Clear();
    Panel pnl = this.CreatePanelWithDynamiControls();
    this.Controls.Add( pnl );
}

void Form1_Load( object sender, EventArgs e ) {
    if ( !this.DesignMode ) {
        this.InitializeDynamicControls();
    }
}

// I don't know exactly, on which situation
// do you want reset controls
void SomeEvent( object sender, EventArgs e ) {
    this.InitializeDynamicControls();
}

Method 2

You could try calling this.InitializeComponent(), which may do the trick. Alternately, if your application has a ‘Directory Select’ form and a ‘Process Files’ form, you could have the Directory Select form do a “new” on the Process Files form, which should return it to its original state (not while its open, though).
