Question

I was wondering  is there a way I can reset all the checkboxes  textboxes  numerics and other controls back to the default values without writing code for every control individually  This is the code I ve tried  but doesn t seem to work     for  int i   0  i  lt  this Controls Count  i          this Controls i  ResetText        EDIT  I ve fixed it by manually setting the control values  sorry for all the trouble    lt

There is a very effective way to use to clear or reset Windows Form C# controls like TextBox, ComboBox, RadioButton, CheckBox, DateTimePicker etc.

private void btnClear_Click(object sender, EventArgs e)
{
    Utilities.ClearAllControls(this);
}

internal class Utilities
{
    internal static void ClearAllControls(Control control)
    {
        foreach (Control c in control.Controls)
        {
            if (c is TextBox)
            {
                ((TextBox)c).Clear();
            }
            else if (c is ComboBox)
            {
                ((ComboBox)c).SelectedIndex = -1;
            }
            else if (c is RadioButton)
            {
                ((RadioButton)c).Checked = false;
            }
            else if (c is CheckBox)
            {
                ((CheckBox)c).Checked = false;
            }
            else if (c is DateTimePicker)
            {
                ((DateTimePicker)c).Value = DateTime.Now; // or null 
            }
        }
    }
}

To accomplish this with overall user experience in c# we can use one statement to clear them. Pretty straight forward so far, above is the code.

If you have some panels or groupboxes reset fields should be recursive    public class Utilities       public static void ResetAllControls Control form                foreach  Control control in form Controls                        RecursiveResetForm control                        private void RecursiveResetForm Control control                            if  control HasChildren                        foreach  Control subControl in control Controls                                RecursiveResetForm subControl                                   switch  control GetType   Name                        case  TextBox                   TextBox textBox    TextBox control                  textBox Text   null                  break               case  ComboBox                   ComboBox comboBox    ComboBox control                  if  comboBox Items Count  gt  0                      comboBox SelectedIndex   0                  break               case  CheckBox                   CheckBox checkBox    CheckBox control                  checkBox Checked   false                  break               case  ListBox                   ListBox listBox    ListBox control                  listBox ClearSelected                    break               case  NumericUpDown                   NumericUpDown numericUpDown    NumericUpDown control                  numericUpDown Value   0                  break
