Asp.Net: Clear inputfields after form submit

Every time a form is successful summited I need to clear all input-fields to the default values and give feedback to the user. I wrote a method ClearControl that can have a control as input parameter. This method will set the control based on his type back to the defaultvalue.

 public static void ClearControl(Control control)
{
 switch (control.GetType().Name)
 {
  case "TextBox":
   TextBox txtBox = (TextBox)control;
   txtBox.Text = "";
   break;
  case "DropDownList":
   DropDownList ddl = (DropDownList)control;
   ddl.SelectedIndex = 0;
   break;
  case "CheckBox":
   CheckBox chk = (CheckBox)control;
   chk.Checked = false;
   break;
  case "CheckBoxList":
   CheckBoxList chkList = (CheckBoxList)control;
   foreach (ListItem li in chkList.Items)
    li.Selected = false;
   break;
  case "Panel":
   ClearFields((Panel)control);
   break;
  case "RadioButtonList":
   RadioButtonList rbl = (RadioButtonList)control;
   rbl.SelectedIndex = -1;
   break;
 }
}

To use this method I wrote a method ‘ClearFields’ that accepts a View or Container control. You can add every type of control that has the .Controls property.

public static void ClearFields(Panel container)
{
 foreach (Control control in container.Controls)
 {
  ClearControl(control);
 }
}

public static void ClearFields(View container)
{
 foreach (Control control in container.Controls)
 {
  ClearControl(control);
 }
}

When I have some time left I will try to implement the ClearFields Method as a ExtensionMethod.
