Question

Im doing this Information retrival search engine that search in Doc files for certain terms using Lucine.net Every thing is going fine I get the results search results in an asp:listbox control.

I managed to get the name of the file and the path of it as shown in the figuer below:

// Using      
 lst_searchResult.Items.Add(doc.Get("title"));
 lst_searchResult.Items.Add(doc.Get("path"));

I would like to perform more operation on the listbox selected Items such as

1. ( Download Document ) using a button .
2. ( Send link Via Email ).

I’m not an expert to be honest with ASP.net , can you please guide me ?

thank you

Answer 1

the asp:listbox is redered as an <select> html control. The appearance of the select control is dertermined by the browser you are using. The only customization option is to set the border/colors/scrollbar of this control.

If you want a more interactive appearance use the asp:listview control. With that you can control how one row of the list is rendered. So you can add buttons, links, etc.

In code you define a DataStructure like

class SearchResult
{
   public string Title {get; set;}
   public string Path {get; set;}
}

And then bind a List<SearchResult> to the listview control.

The markup for the ListView could look something like this:

<asp:ListView runat="server" ID="ListView1">
  <LayoutTemplate>
    <table>
      <tr runat="server" id="itemPlaceholder" ></tr>
    </table>
  </LayoutTemplate>
  <ItemTemplate>
    <tr>
      <td><a href='<%#Eval("Path") %>'><%#Eval("Title") %></a></td>
    </tr>
  </ItemTemplate>
</asp:ListView>

This link shows a bunch of examples on how to use the ListView control:
