trouble with aspnet inline if statement

[dorandoran]

<% if(txtEmpID.Text!=null) Response.Write("<a href='Assign_Dept.aspx?id=" + txtEmpID.Text + "&sname=" + txtlname.Text + ", " + txtfname.Text + "' + target='_new' + toolbar='no'' > Testing Response with IF </a>"); %>

How come "Testing Response with IF" still shows up when txtEmpID is Null?

Still same problem. The link should only appear if there is an ID in the txtEmpID textbox.

<% if (txtEmpID.Text != null)
{
Response.Write("<a href='Assign_Dept.aspx?id=" + txtEmpID.Text + "&sname=" + txtlname.Text + ", " + txtfname.Text + "' + target='_new' + toolbar='no'' > Click Here . . .</a>");
}
else
{
Response.Write("Please select a record.");
}  
%>

You are checking for null, not an empty string. check for the empty string too.
I rather like string.IsNullOr Empty() for this purpose
