MY purpose is that develop a web form with textboxes to display database
contents.
In design time, I follow the .Net document and click data binding property
field in each TextBox, select the corresponding colunm name of database table
to each textbox.

In the Page_Load procedure, I type me.databind().
Compiling is OK. When I run it, I got the following error message.
Did I do any thing wrong? How to do it?

Thank you for your help.

David,

I'm not sure what database type you're using, but you'll want to double
check to make sure whatever method you're using (Query or Stored Procedure)
is actually returning data. You have it hard coded to put data from row 0
into the textbox.
I wouldn't suggest ever hardcoding a specific row's value to a field unless
that page will always return a single row no matter what.

Either way, double check your data, that seems to be the culprit.
