Clear the Controls Data on Click of Reset Button

I have 20 controls on my web page. I want to clear the controls data when onclick of reset button:
private void ClearControls(Control parent)
{
foreach (Control _ChildControl in parent.Controls)
{
if ((_ChildControl.Controls.Count > 0))
{
ClearControls(_ChildControl);
}
else
{
if (_ChildControl is TextBox)
{
((TextBox)_ChildControl).Text = string.Empty;
}
else
if (_ChildControl is CheckBox)
{
((CheckBox)_ChildControl).Checked = false;
}
else
if (_ChildControl is DropDownList)
{
((DropDownList)_ChildControl).SelectedIndex = 0;
}
else
if (_ChildControl is ListBox)
{
((ListBox)_ChildControl).SelectedIndex = 0;
}
}
}
}


calling this function like this:pn click of reset button
ClearControls(this.Page);

C# Conditions in 2 different ways

One Way is
if (item.Text.ToString() == "Professional")
query1 = "P";
else
query1 = "C";

--------
query1 = item.Text.ToString() == "Professional" ? "P" : "C";

================Separate
if (item.Selected == true)
query1 = item.Text.ToString() == "Professional" ? "P" : "C";
---------
if (item.Selected != true) continue;
query1 = item.Text.ToString() == "Professional" ? "P" : "C";
