                        Text='<%# string.Format("{0}",Eval("New_Content").ToString().Length>150? <a href> Eval("New_Content").ToString().PadRight(150).Substring(0,150).TrimEnd() + " ..." </a>:Eval("New_Content")) %>' >
                    </asp:Label>

I am trying to create hyper link

Well why not use a <asp:HyperLink /> control then?

Also don't string use Substring() to reduce the length of the text and add the ... at the end, just use css.

e.g.

<asp:HyperLink ID="hlContent" runat="server" CssClass="trimme" 
                Text='<%# Eval("New_Content").ToString() %>'></asp:HyperLink>

Then add a css class called trimme

a.trimme{
  display: block;  
  width: 150px;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

Take a look at this example

good idea for using css in trimming, but how can I make the text to be more than one line, and I am not using <asp:HyperLink> because I want to use the link only if the text length more thank 150 characters

The code you had was almost correct, it just seems that you are missing some quotes:

<asp:Label ID="lblContent" runat="server" 
    Text='<%# String.Format("{0}", Eval("New_Content").ToString().Length > 150 ? "<a href='" + Eval("Link_Href") + Eval("New_Content").ToString().PadRight(150).Substring(0, 150).TrimEnd() + "'>...</a>" : Eval("New_Content")) %>' >
</asp:Label>

The text in an ASP Label is output raw to the response stream, so you can just write standard HTML, but it does need to be in quotes as you are building a new string object.

I got the solution using LastIndexOf() as:

<asp:Label ID="lblContent" runat="server" CssClass="nostyle" 
                        Text='<%# string.Format("{0}",Eval("New_Content").ToString().Length>150?string.Format("<a href=news.aspx?page=3#{0}>{1}</a>",Eval("New_Id"),string.Format("{0} {1}",Eval("New_Content").ToString().PadRight(150).Substring(0,Eval("New_Content").ToString().PadRight(150).Substring(0,150).LastIndexOf(" ")>-1 ? Eval("New_Content").ToString().PadRight(150).Substring(0,150).LastIndexOf(" "): 150).ToString(), " ...")):Eval("New_Content")) %>' >
                    </asp:Label>

Thank you all, you gave me good ideas
