<p>I can't seem to figure as to why the javascript code below gives me the document.getelementbyid is null or not an object on this line: line: 111. As to my knowledge all should be working as ive declared everything</p> <pre><code>var rows = document.getElementById("mstrTable").getElementsByTagName("tr"); </code></pre> <p>Here's the complete code:</p> <pre><code> <html> <head> <title>Scrolling Data Grid</title> <style> /* ==================================================================== */ /* SCROLLING DATA GRID - IE ONLY! */ /* ==================================================================== */ /* Tables inside a scrollingdatagrid should have: 1. border-collapse:separate 2.

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.
