    <p>Here's a low tech solution. It doesn't require use of web services or any other additional technologies.</p> <p><strong>Step 1</strong></p> <p>Have an ASPX page that takes one paramter, and invoked like this:</p> <pre><code>http://mysite.com/query.aspx?sql=select * from orders where status = 'open' </code></pre> <p><strong>Step 2</strong></p> <p>In the code behind, do something like this</p> <pre><code>void Page_Load(object sender, EventArgs e) { Response.ContentType="text/json"; DataTable contents = ExecuteDataTable(Request["sql"]); Response.Write( JRockSerialize( contents ) ); Response.End(); } </code></pre> <p>You can use <a href="http://jayrock.berlios.de/" rel="nofollow noreferrer">JRock</a> for serializing a data table to JSON. IMHO this gives the cleanest JSON. </p> <p>So that's getting <code>DataTable</code> to JSON sorted...</p> <p><em>WARNING: This is obviously a simplistic example. You shouldn't pass SQL on the query string as it is not secure (your could use named queries and parameters instead).</em></p> <p><strong>Step 3</strong></p> <p>In your ExtJS code, create a grid with Json datastore as shown in this <a href="http://www.extjs.com/deploy/dev/examples/grid/binding.html" rel="nofollow noreferrer">Ext example</a>. Set the data store <code>url:</code> to that of your query.aspx page with appropriate query string parameters. </p> <p>You'll also need to set the columns up for the grid, again shown in the ExtJs example.</p> <p><strong>Alternatively...</strong></p> <p>I was really impressed when I looked at the <a href="http://www.coolite.com/" rel="nofollow noreferrer">Coolite samples</a> recently. They are an ExtJS partner and provide a good ASP.NET &amp; ExtJS experience. And no, I don't work for them :) I haven't tried their grid, but it might be painless (at a price).</p>

    1. COYuck. You should mark your WARNING red, bold and blinking. Never, NEVER, _NEVER_ have a page that allows you to do "sql=select * from orders where status = 'open'"! Don't do it! I mean it! That's just like putting up a sign "Come here and hack me. Copy my database and then delete all data I have!"

Querying!

 
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.

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).
