    <p>You can use ClientScript.RegisterStartUpScript to inject javascript into the page on Page_Load.</p> <p>Here's a link to MSDN reference: <a href="http://msdn.microsoft.com/en-us/library/asz8zsxy.aspx" rel="noreferrer">http://msdn.microsoft.com/en-us/library/asz8zsxy.aspx</a></p> <p>Here's the code in Page_Load:</p> <pre><code> List&lt;string&gt; tempString = new List&lt;string&gt;(); tempString.Add("Hello"); tempString.Add("World"); StringBuilder sb = new StringBuilder(); sb.Append("&lt;script&gt;"); sb.Append("var testArray = new Array;"); foreach(string str in tempString) { sb.Append("testArray.push('" + str + "');"); } sb.Append("&lt;/script&gt;"); ClientScript.RegisterStartupScript(this.GetType(), "TestArrayScript", sb.ToString()); </code></pre> <p>Notes: Use StringBuilder to build the script string as it will probably be long.</p> <p>And here's the Javascript that checks for the injected array "testArray" before you can work with it:</p> <pre><code>if (testArray) { // do something with testArray } </code></pre> <p>There's 2 problems here:</p> <ol> <li><p>Some consider this intrusive for C# to inject Javascript</p></li> <li><p>We'll have to declare the array at a global context</p></li> </ol> <p>If you can't live with that, another way would be to have the C# code save the Array into View State, then have the JavaScript use PageMethods (or web services) to call back to the server to get that View State object as an array. But I think that may be overkill for something like this.</p>

    1. COI'll take a look thanks for the explanation. One thing, which array are you referring to as global and why?

    3. CO@Gary: My concern here is the ad hoc serialization. If the strings in that list were to contain single quotes, we'd have a problem. That's why using the JSON serializer is safer.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
