Clearing input controls at a stretch in ASP.Net

There will be situations where we will develop an input form for bulk input processing. Obviously, these forms will have large number of input controls like textbox, dropdownlist, checkbox and radiobutton, etc. In such forms, we need to reset these control once the input is processed for the subsequent request. You can use the below code to reset the input controls at a stretch instead of clearing it one by one.

[Updated code as per the user comments - Thanks to gramotei and Sean]

private void btnClear_Click(object sender, System.EventArgs e)

{

Control myForm = Page.FindControl("Form1");

        foreach (Control ctrl in myForm.Controls)

        {

            //Clears TextBox

            if (ctrl is System.Web.UI.WebControls.TextBox)

            {

                (ctrl as TextBox).Text = "";

            }

            //Clears DropDown Selection

            if (ctrl is System.Web.UI.WebControls.DropDownList)

            {

                (ctrl as DropDownList).ClearSelection();

            }

            //Clears ListBox Selection

            if (ctrl is System.Web.UI.WebControls.ListBox)

            {

                (ctrl as ListBox).ClearSelection();

            }

            //Clears CheckBox Selection

            if (ctrl is System.Web.UI.WebControls.CheckBox)

            {

                (ctrl as CheckBox).Checked = false;

            }

            //Clears RadioButton Selection

            if (ctrl is System.Web.UI.WebControls.RadioButtonList)

            {

                (ctrl as RadioButtonList).ClearSelection();

            }

            //Clears CheckBox Selection

            if (ctrl is System.Web.UI.WebControls.CheckBoxList)

            {

                (ctrl as CheckBoxList).ClearSelection();

            }

        }

}
