    <p>I am currently adding keyboard shortcuts to our web application, so from JavaScript.</p> <p>So far, it has consisted mostly in triggering the click events of buttons already exposed in the user-interface.</p> <p>Now, I would like to add another one which redirects to another page. The new page URL needs to be generated based on elements from the source page query string. Basically, I have a date in the query string and I want to generate a new URL for the next day.</p> <p>I feel that it would be easier to do it server-side, using the DateTime methods and then Response.Redirect than simply using JavaScript.</p> <p>I've tried decorating a method using and then calling it from the Javascript. However, for WebMethods to work, I need to enable EnablePageMethods to true on the ScriptManager and when I do that, I am getting errors like this. The ScriptManager currently is in the master page, so its feature is automatically inherited to all contents pages as well.</p> <p>It basically looks like this:</p> <pre><code> &lt;asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="True" EnablePageMethods="True"&gt;&lt;/asp:ScriptManager&gt; </code></pre> <p>When I add the EnablePageMethods attribute, and then run the application, I get this ASP.Net error:</p> <p>Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. </p> <pre><code>Parser Error Message: Required attribute 'name' not found. Source Error: &lt;jsonSerialization maxJsonLength="500"&gt; &lt;converters&gt; &lt;add type="Microsoft.Web.Script.Serialization.Converters.DataSetConverter"/&gt; &lt;add type="Microsoft.Web.Script.Serialization.Converters.DataRowConverter"/&gt; &lt;add type="Microsoft.Web.Script.Serialization.Converters.DataTableConverter"/&gt; </code></pre> <p>I am not sure what I need to do to solve this error, so I would need to either find a way to fix this or find a workaround to execute my server-side method without relying on EnablePageMethods. I am thinking about adding an invisible button to the webpage and simulating a click to it to execute my server-side method, but that looks like a relatively unclean workaround.</p> <p>Can somebody please help / give some pointers? I am using ASP.Net in VB 2005 in NET 2.0.</p> <p>Thanks in advance.</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.
