Thank you. I have an addtional question. I have a simple one row, 5 cell table. The first cell contains the date 2/29/2004. I set up a simple script to gain access to the cell. I can get to the id, align and valign attributes of the cell once I getElementById. But how do I get to the text (2/29/2004). GetCellStuff() is set up to ALERT() the id (for this example) but what would be the syntax to get to 2/29/2004. The properties text and value do not work.
<td id="DateID" align="Left" valign="Top">2/29/2004</td>

<script language='javascript'> 
  function GetCellStuff()
  { 
     var cellTxt=document.getElementById('DateID'); 
     // return false to prevent server control post back
     alert('The property is: ' + cellTxt.id); return false; 
  }
</script>
Thank you,
Neil

>>Hi,

>>I built a 1 row, 5 column html table in the page load event. I have complete server side control of all of the cells in the table via:

>>or I can set a property of a cell via:

>>this.Table1.Row[0].Cells[0].BackColor=Color.Yellow;

>>
>>But now I need to control some the properties and text via client side JavaScript. How do I need to set up the table, rows and columns so that I can control these elements via JavaScript. Can someone also offer an example of JavaScript that does this?
