    <p>You need to use <a href="http://msdn.microsoft.com/en-us/library/system.datetime.parseexact.aspx"><code>DateTime.ParseExact</code></a> with format <code>"dd/MM/yyyy"</code></p> <pre><code>DateTime dt=DateTime.ParseExact("24/01/2013", "dd/MM/yyyy", CultureInfo.InvariantCulture); </code></pre> <p>Its safer if you use <code>d/M/yyyy</code> for the format, since that will handle both single digit and double digits day/month. But that really depends if you are expecting single/double digit values. </p> <hr> <p>Your date format <code>day/Month/Year</code> might be an acceptable date format for some cultures. For example for Canadian Culture <code>en-CA</code> <code>DateTime.Parse</code> would work like:</p> <pre><code>DateTime dt = DateTime.Parse("24/01/2013", new CultureInfo("en-CA")); </code></pre> <p>Or </p> <pre><code>System.Threading.Thread.CurrentThread.CurrentCulture = new CultureInfo("en-CA"); DateTime dt = DateTime.Parse("24/01/2013"); //uses the current Thread's culture </code></pre> <p>Both the above lines would work because the the string's format is acceptable for <code>en-CA</code> culture. Since you are not supplying any culture to your <code>DateTime.Parse</code> call, your current culture is used for parsing which doesn't support the date format. Read more about it at <a href="http://msdn.microsoft.com/en-us/library/system.datetime.parse(v=vs.110).aspx">DateTime.Parse</a>. </p> <hr> <p>Another method for parsing is using <a href="http://msdn.microsoft.com/en-us/library/system.datetime.tryparse(v=vs.110).aspx"><code>DateTime.TryParseExact</code></a></p> <pre><code>DateTime dt; if (DateTime.TryParseExact("24/01/2013", "d/M/yyyy", CultureInfo.InvariantCulture, DateTimeStyles.None, out dt)) { //valid date } else { //invalid date } </code></pre> <p>The <code>TryParse</code> group of methods in .Net framework doesn't throw exception on invalid values, instead they return a <code>bool</code> value indicating success or failure in parsing. </p> <p><strong>Notice</strong> that I have used single <code>d</code> and <code>M</code> for day and month respectively. Single <code>d</code> and <code>M</code> works for both single/double digits day and month. So for the format <code>d/M/yyyy</code> valid values could be:</p> <ul> <li>"24/01/2013"</li> <li>"24/1/2013"</li> <li>"4/12/2013" //4 December 2013</li> <li>"04/12/2013"</li> </ul> <p>For further reading you should see: <a href="http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx">Custom Date and Time Format Strings</a></p>

    1. COThanks a lot. I had already tried the DateTime.ParseExact() but I guess the trick was with the null as third argument. I was using CultureInfo.InvariantCulture instead which would give me a compilation error.

    2. CO@user1872530, you are welcome, it should have worked for you, but I guess you are missing using statement for System.Globalization, so try `System.Globalization.CultureInfo.InvariantCulture` instead,

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.
