You're not validating the dropdown list are you? You're validating the value a user selected. It's pretty much the same advice as the other post, since javascript or other tools can alter the html or create their own POST's, you must always validate on the server side. Assume all client requests can be tampered with, and assume that no client-side validation has occurred. <hr> If you're using the web forms model .... If you just want to check a value was selected in the dropdown <code>myAjaxDropDown</code>, use the <pre><code><asp:RequiredFieldValidator id="dropdownRequiredFieldValidator" ControlToValidate="myAjaxDropDown" Display="Static" InitialValue="" runat=server> * </asp:RequiredFieldValidator> </code></pre> You could also want to look at the asp:CustomValidator - for server side validation: <pre><code><asp:CustomValidator ID="myCustomValidator" runat="server" onservervalidate="myCustomValidator_ServerValidate" ErrorMessage="Bad Value" /> </code></pre> Both plug into the validation framework of asp.net. e.g. when you click a button called <code>SumbitButton</code> <pre><code>protected void myCustomValidator_ServerValidate(object source, ServerValidateEventArgs e) { // determine validity for this custom validator e.IsValid = DropdownValueInRange(myAjaxDropDown.SelectedItem.Value); } protected void SubmitButton_Click( object source, EventArgs e ) { Validate(); if( !IsValid ) return; // validators pass. Continue processing. } </code></pre> Some links for further reading: <ul> <li><a href="http://quickstart.developerfusion.co.uk/QuickStart/aspnet/doc/validation/default.aspx" rel="nofollow noreferrer">ASP.Net 2.0 Quickstart - Validating Form Input Controls</a></li> <li><a href="http://www.dotnetcurry.com/ShowArticle.aspx?ID=121&AspxAutoDetectCookieSupport=1" rel="nofollow noreferrer">ASP.NET Validation Controls – Important Points, Tips and Tricks</a></li> </ul>

Guidance

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.
