I'm not quite following the problem. If you don't want to display data on form load then remove that particular code.

I'm not quite following the problem. If you don't want to display data on form load then remove that particular code.
What does this code consists off so I can try and get rid of it.
The first row is displayed within the text box upon load.
Please post your code here.
