VS 2008 Changing Label To TextBox On Run Time

First, my code:

Code:
<asp:Table>
<asp:TableRow>
<asp:TableCell>Name:</asp:TableCell>
<asp:TableCell><asp:Label>John Doe</asp:Label></asp:TableCell>
</asp:TableRow>
</asp:Table>

I want to change the Label Control to a Textbox Control once I've triggered a Button.Click event. So my output will be:

Code:

<asp:Table>
<asp:TableRow>
<asp:TableCell>Name:</asp:TableCell>
<asp:TableCell><asp:TextBox>John Doe</asp:TextBox></asp:TableCell>
</asp:TableRow>
</asp:Table>

The label part is for display the information from the database. I'm using a button as a trigger to edit that label by changing it to a textbox and I'll be using another button as a trigger to save the changes made in the textbox and then changing it back to a label.
