Data binding at design time. How to work with them. I got error me

david

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.

Question: How to show a property of a component for data binding at design time

What interface do I need to implement in order to get a component with a public property to show up in the data binding drop down boxes at design time in VS.net? I've tried to look just about every where I can think and I can not find the solution. The closest I can come is to implement IBindingList or IListSource to expose a list for the DataSource property on controls. This works great for controls like a list box but doesn't work...
