从SQL数据库检索动态内容并将其显示到ASP.NET页中

Question

I am currently working on the development of news portal website in asp.net. I have created a table in sql server 2008 with parameters (NewsId, NewsTitle, NewsDetails, NewsCategory). I am now able to dynamically retrieve the NewsTitle from the database and displaying it in my aspx page. Now I want to pass the NewsId for that particular NewsTitle and then retrieve the NewsDetails in a separate aspx page. What is the best thing to do this in ASP.NET? I don't want to create new aspx pages every time a link to the NewsTitle is clicked, rather I am interested to use the same Details page and pass different ID parameters?

regards,

Answer 1

I'd keep them both on the same page and employ a master-details pattern using something like panels to toggle the visibility:

This will give you the basic idea; the sample linked to shows both, but as I said it is a simple matter to toggle them on and off on the click of a button.

You can do the following approach:

1. Take HyperLink in a Gridview to show a NewsTitle:

    <asp:GridView ID="GridView1" runat="server"> <Columns> <asp:TemplateField> <ItemTemplate> <asp:HyperLink runat="server" ID="hl" NavigateUrl='<%#"NewsDetails.aspx?Newsid="+ Eval("NewsId") %>' Text='<%# Eval("NewsTitle") %>'></asp:HyperLink> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> 

   Bind the GridView datasource in code behind:

    protected void getNewsDetails() { DataTable dtNewsDetails = new DataTable(); //retrieve data from database into the DataTable GridView1.DataSource = dtNewsDetails; GridView1.DataBind(); } 

2. Now as GridView HyperLink will navigate to the NewsDetails.aspx with a NewsId as querystring, show the details accordingly in a NewsDetails.aspx page:

   protected void Page_Load(object sender, EventArgs e) { string Newsid = Request.QueryString["Newsid"].ToString(); //show the details from database using Newsid }

Answer 3

You can add a textBox with visible attribute set as False and when you retrieve the NewsDetails set it to textBox and set it visibility to True;

<asp:TextBox ID="NewsDetails" runat="server" TextMode="MultiLine" 
                        Height="30px" Width="200px" Visible="False" />

and

void GetNewsDetails()
{
NewsDetails.Text=GetDetailsQuery;
NewsDetails.Visible=True;
}
