Hi Susan,

Here is the code to rest the values of the TextBoxes http://www.dotnetfunda.com/codes/code9-how-to-empty-all-textboxes-of-the-page-at-one-shot-.aspx

If you can enhance this code by changing this like if (c is TextBox) for the dropdown or other controls this would become what you are looking for.

In case you are looking for using the JavaScript, read this http://www.dotnetfunda.com/codes/code599-reset-all-form-elements-to-their-default-values-in-javascript-.aspx.

Thanks

Hi,
To clear textbox use 
TextBox1.Text = string.Empty;

To clear radio button checkboxes.. 
CheckBox2.Checked = false;

 RadioButton1.Checked = false;

For dropdownlist use like this.. 
<asp:DropDownList ID="DropDownList2" AutoPostBack="true" runat="server" 

                        onselectedindexchanged="DropDownList2_SelectedIndexChanged">

                    <asp:ListItem Value="0" >--select--</asp:ListItem>

                    <asp:ListItem Value="1" >item1</asp:ListItem>

                    <asp:ListItem Value="2" >item2</asp:ListItem>

                    <asp:ListItem Value="3" >item3</asp:ListItem>

                    </asp:DropDownList>

to clear selection.. 
DropDownList2.SelectedValue = "0";


Thanks & Regards,

Hi please try to use this for clearing Text boxes. 
 void GetAllTextBox(Control ctrl)

    {

        if (ctrl != null)

        {

            foreach (Control c in ctrl.Controls)

            {

                if (c is TextBox)

                {

                    ((TextBox)c).Text = String.Empty;

                }

Write down code like:

foreach(Control ct in Page.Controls)
{
if (ct is typeof(TextBox))
((TextBox)ct).Text = string.Empty;
else{
if(ct is typeof(DropDownList))
((DropDownList)ct).ClearSelection();
}
}


this way u can write statement for each control which are there on ur page.
