}
public void ResetControl(Control Parent)
{
foreach (Control c in Parent.Controls)
{
switch (c.GetType().ToString())
{
case "System.Web.UI.WebControls.TextBox":
((TextBox)c).Text = "";
break;
case "System.Web.UI.WebControls.CheckBox":
((CheckBox)c).Checked = false;
break;
case "System.Web.UI.WebControls.RadioButton":
((RadioButton)c).Checked = false;
break;
}
}
}
Javascript:
You can add client event in button .
<script language="javascript" type='text/javascript'>
function CLSEvent()
{
for (i=0; i<document.forms[0].length; i++)
{
doc = document.forms[0].elements[i];
switch (doc.type)
{
case "text" :
doc.value = "";
break;
case "checkbox" :
doc.checked = false;
break;
case "radio" :
doc.checked = false;
break;
case "select-one" :
doc.options[doc.selectedIndex].selected = false;
break;case "select-multiple" :
while (doc.selectedIndex != -1)
{
indx = doc.selectedIndex;
doc.options[indx].selected = false;
}
doc.selected = false;
break;
default :
