    <p>I would like to use substitution feature of donut caching. </p> <pre><code>public static string GetTime(HttpContext context) { return DateTime.Now.ToString("T"); } </code></pre> <p>...</p> <pre><code>The cached time is: &lt;%= DateTime.Now.ToString("T") %&gt; &lt;hr /&gt; The substitution time is: &lt;% Response.WriteSubstitution(GetTime); %&gt; </code></pre> <p>...But I would like to pass additional parameter to callback function beside HttpContext.<br> so the question is:<br> <strong>How to pass additional argument to GetTime callback?</strong><br> for instance, something like this:</p> <pre><code>public static string GetTime(HttpContext context, int newArgument) { // i'd like to get sth from DB by newArgument // return data depending on the db values // ... this example is too simple for my usage if (newArgument == 1) return ""; else return DateTime.Now.ToString("T"); } </code></pre>

    1. COSo the answer i was looking for is: IT CAN NOT BE DONE :) Problem in my situation is that i'm dinamically inserting multiple(>=0) POLL controls on the page and I want to render each control based on arguments (UserID and PollID. if user has already voted, there must be results of the poll instead of voting form, for each control). So I can not define different functions. In the end i've used ajax call to retrieve results for each of the voted poll on $(document).ready event. But I was hoping for a nicer solution... Thanks to all for your help

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.
