Adding hyperlinks to labels in certain cases, when dealing with databound repeater

Sounds a bit cluttered, but basically I have a databound repeater. On the ASP side, I have this:

<asp:Label ID="Label2" runat="server" Text='<%#Eval("uMessage") %>'></asp:Label>

I'm using the same template for 4 different datasets, and for 2 of them this should be a hyperlink and for the other 2 it shouldn't. So, I'm guessing you have to add a hyperlink programmatically in the code-behind? Has anyone ever done something like this?

Easiest way without all kinds of code-behind and therefor less code fragmentation, I would say you need a property that is set based on your condition prior to data binding.

protected bool LinkVisible { get; set; }

Then you just do this:

<asp:Label ID="Label2" runat="server" Text='<%#Eval("uMessage") %>' Visible="<%# !LinkVisible %>"></asp:Label>
<asp:HyperLink ID="Link" runat="server" Visible="<%# LinkVisible %>" ><%#Eval("uMessage") %></asp:HyperLink>

This sets the Visible for either the Label or the HyperLink. Visible false means it won't even get rendered. In your markup you can see that there will be a label or a hyperlink and no special things popup from the code behind.

You don't need to add the property LinkVisible, but can do the condition there too.

yes it is possible in code behind on DataItem bound

if (e.Row.RowType == DataControlRowType.DataRow)
    {
        Label lbl = (Label)e.Row.FindControl("Label2");
        if (lbl.Text == "your condition")
        {
            HyperLink yourLink = (HyperLink)e.Row.FindControl("yourID");
            yourLink.enabled = false;
        }
    }
