Add hyperlink based on the user

Hi,

I have a very basic question. I have a single column datalist on my webpage which is a hyperlink and takes you to another page when clicked. I want to make this column a hyperlink based on the user permissions. So if the user has permission 'A' allow him to click on the link. Basically I want to make it a hyperlink if user has permission 'A' otherwise it should just be a simple text. Can anyone tell me how to do this.

Thanks for your help.

It should be a simple If-Then statement in the ASP code. If permission = 'A' then Response.Write the link. If not, Response.Write as text.

Sorry I am really new to ASP .Net. I am not sure where I can add the if then statements. I am in the site.master page and here is what I have so far

Code:

---

<ItemTemplate>
          <asp:HyperLink ID="HyperLink1" runat="server"                    NavigateUrl="~/temp.aspx"
            Text='<%# Eval("SummaryTxt") %>'  ></asp:HyperLink>
            </ItemTemplate>

---

For this I want to check if user = "A" then

Code:

---

        <asp:HyperLink ID="HyperLink1" runat="server"                    NavigateUrl="~/temp.aspx"
            Text='<%# Eval("SummaryTxt") %>'  ></asp:HyperLink>

---

else

Code:

---

  <asp:Label ID="Label1" runat="server"
                                                    Text='<%# Eval("OutageSummaryTxt") %>'  ></asp:Label>

---

Here are my questions.
1. How do I declare the variable user.
2. How do I start the if then clause.

Thanks for your help.
