I do remember seeing someone ask something along these lines a while ago but I did a search and couldn\'t find anything.

Below are methods I use to clear text from a type of control that implements ITextBox.

I noticed in the example default boolean values are set. I'm sure you can modify it to set default values of boolean components.

Pass the Clear method a control type (TextBox, Label... etc) and a control collection, and it will clear all text from controls that implement ITextBox.

Something like this:

//Clears the textboxes
WebControlUtilities.ClearControls(myPanel.Controls);

The Clear method is meant for a Page or Masterpage. The control collection type may vary. ie. Form, ContentPlaceHolder.. etc

        /// 

    /// Clears Text from Controls...ie TextBox, Label, anything that implements ITextBox
    /// 
    /// Collection Type, ie. ContentPlaceHolder..
    /// ie TextBox, Label, anything that implements ITextBox
    /// 
    public static void Clear(ControlCollection controls)
        where C : ITextControl
        where T : Control
    {
        IEnumerable placeHolders = controls.OfType();
        List holders = placeHolders.ToList();

        foreach (T holder in holders)
        {
            IEnumerable enumBoxes = holder.Controls.OfType();
            List boxes = enumBoxes.ToList();

            foreach (C box in boxes)
            {
                box.Text = string.Empty;
            }
        }
    }

    /// 

    /// Clears the text from control.
    /// 
    /// 
    /// The controls.
    public static void ClearControls(ControlCollection controls) where C : ITextControl
    {
        IEnumerable enumBoxes = controls.OfType();
        List boxes = enumBoxes.ToList();

        foreach (C box in boxes)
        {
            box.Text = string.Empty;
        }
    }
