    <p>I don't understand how you can only get the number of needed rows from a database when you need to know the total amount of rows inorder to get paging to work.</p> <p>What I mean is: I followed this example: <a href="http://www.c-sharpcorner.com/uploadfile/rizwan328/datalist-custom-paging-in-Asp-Net-using-C-Sharp/" rel="nofollow">http://www.c-sharpcorner.com/uploadfile/rizwan328/datalist-custom-paging-in-Asp-Net-using-C-Sharp/</a></p> <p>But instead of using a dataTable I have a database.</p> <p>I get the news from the database like this, this gets all the news from my news table:</p> <pre><code>List&lt;News&gt; news = News.GetNews(); public static List&lt;News&gt; GetNews(){ List&lt;News&gt; news = new List&lt;News&gt;(); using (SqlConnection conn = new SqlConnection(CONNSTRING)) { SqlCommand cmd = new SqlCommand("SELECT * FROM News_news ORDER BY date DESC", conn); </code></pre> <p>That gets all the data from all the news items.</p> <p>Then I create a PagedDataSource:</p> <pre><code>PagedDataSource objPds = new PagedDataSource(); objPds.DataSource = news; objPds.AllowPaging = true; objPds.PageSize = numRows; //Set the current page objPds.CurrentPageIndex = CurrentPage; //Set the buttons </code></pre> <p>Putt the data in a repeater that will show the first 5 items on the aspx page</p> <pre><code>repeater1.DataSource = objPds; repeater1.DataBind(); </code></pre> <p>Like this I have a paged front page that shows me the total number of pages and the current page and when I click on the button for the next page I do it all over again.</p> <p>But I know this isn't correct since I always get all the news and then discared the news I don't need. but please, how do need to do it so that I only get the needed news items?</p> <p>Do I need to first count the number of rows in my table?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
