1. how to clear controls in asp.net c#
private void ClearControls(Control parent)
{
foreach (Control _ChildControl in parent.Controls)
{
if ((_ChildControl.Controls.Count > 0))
{
ClearControls(_ChildControl);
}
else
{

2. Ways to Clear Controls values in the Page
1. Creating method that would loop through the page controls and clear its values accordingly like:
private void ClearControls()

{

foreach (Control c in Page.Controls)

{

if (c.GetType().ToString() == "System.Web.UI.WebControls.TextBox")

{

TextBox tb = (TextBox)c;

if (tb != null)

{

tb.Text = string.Empty;

}

}

if (c.GetType().ToString() == "System.Web.UI.WebControls.DropDownList")

{

DropDownList ddl = (DropDownList)c;

if (ddl != null)

{

ddl.ClearSelection();

}

}

}

2. Creating a generic Recursive FindControl method that would search all the Controls in the page and reset their values.
public static void ClearControls(Control Parent)

{

if (Parent is TextBox)

{ (Parent as TextBox).Text = string.Empty; }

else

{

foreach (Control c in Parent.Controls)

ClearControls(c);

}

}

//Then call the method like this

ClearControls(Page)

3. Using HTML Input type RESET Button
input type="reset" value="Reset form

4. Redirect to the same page using Response.Redirect method.
Response.Redirect("YourPage.aspx");
