ASP.NET Listview->Click Row->Perform action

问题

I need some help with the following.

I have a list view that I fill with code-behind:

Linq->Sql:

        ListView1.DataSource = from x in database.ITEMS
                               select x;
        ListView1.DataBind();

Content of ITEMS:

ID
Name
Quantity

I only show the name of the fields:

        <tr>
            <td>
                <asp:Label ID="nameLabel" runat="server" Text='<%# Eval("Name") %>' />
            </td>
        </tr>

Assuming I have 25 rows in the database, I fill the list view with 25 rows. Next is what I need help with. The user needs to click one of the 25 names (complete row) and redirects to a page where the content of that row is showed. So lets say someone clicks on "Cars", he'll be redirected and he will see: You have selected Cars, Cars has an ID of 19 and a Quantity of 6.

I have browsed the Internet already but I am having trouble finding solutions that I can understand. I am kind of a noob when it comes to list views and other data displaying methods.

My 2 questions:

How do I start a event when I click a row (and not a button or a link in that row)?
When I click a row and start a event, how can I check which one was clicked?

I hope someone can explain to me how this is done in a user friendly noob kind of way or redirect me to a tutorial discussing my issue's and also in a user friendly way. Thanks in advance.

Ok - I am not sure if this is the best way to go with this (I'll be interested what other think)... but this will work .

Update your listview to something like this:

        <script type="text/javascript">
            // simple redirect to your detail page, passing the selected ID 
            function redir(id) {
                window.location.href = "mydetailpage.aspx?id=" + id;
            }
        </script>
        <table>
        <asp:ListView ID="ListView1" runat="server">
            <ItemTemplate>
                <tr onclick="redir('<%# Eval("ID") %>');">
                    <td>
                        <asp:Label ID="nameLabel" runat="server" Text='<%# Eval("Name") %>' />
                    </td>
                </tr>
            </ItemTemplate>
        </asp:ListView>
        </table>

Then create another page to show your detail (e.g. mydetailpage.aspx) - this should requery your database and show the other fields, given the id passed in the querystring.

you can define onclick attribute to call javascript function on tr element like this :

onclick="yourfunction('<%# Eval("Name") %>');"

Then you can put anything in your javascript function like redirect to another page
