Could you please tell me why I can't get any data to show up in this very simple grid? I selected your Vista template, defined two static columns and their associated DataFields, set the DataSource in the page load and called DataBind. I get a blank, bordered box. No errors, just a blank box. There are 81 records in the grid1.recordcount. This is the first time I've tried to use your grid control. Totally baffled. Thanks, Tod

Hi,
Your code looks perfectly fine to us. As long as the Grid has rows, you should see at least row numbers. Otherwise I can only think that somewhere else in your code the Grid is cleared out. You may also want to try your code in a blank page, that should tell you whether it has anything to do with other contents in your page, particular your stylesheet.
Thanks!
