Do this in your code behind:

public string thisUrlFormat = "<a href='http://www.xyz.com/WebForm1.aspx?Name={0}>Click Here</a>";

and when you need to use it in your HTML, do this:

<%=string.Format(thisUrlFormat, PersonName.ToString())%>

If you need to add more parameters, add the appropriate format specifiers to thisUrlFormat after "{0}":

"?AnotherParam={1}"

and change your html to look like this:

<%=string.Format(thisUrlFormat, PersonName.ToString(), 5)%>
