In some applications we may need to reset all controls in using a single "Reset" button click, here is the c# code to achieve this.

  public  static void ResetControls(ControlCollection pagecontrols, bool txtbox, bool dropdownlist, bool label)
    {
        foreach (Control cntrl in pagecontrols)
        {
            foreach (Control mycontrols in cntrl.Controls)
            {
                if (txtbox)
                {
                    if (mycontrols is TextBox)
                    {
                        (mycontrols as TextBox).Text = string.Empty;
                    }
                }
                if (dropdownlist)
                {
                    if (mycontrols is DropDownList)
                    {
                        (mycontrols as DropDownList).SelectedIndex = 0;
                    }
                }
                if (label)
                {
                    if (mycontrols is Label)
                    {
                        (mycontrols as Label).Text = string.Empty;
                    }
                }
            }
        }
    }

We can call this function using following format if you want to clear all controls except label

FormControl.ResetControls(this.Controls, true, true, false);
