write your code under the page load method in the if(!ispostback) { } I think it will work

If you must rebind, then try:

((CurrencyManager)list_event.BindingContext[list_event.DataSource]).Refresh();

Exception is :Items collection cannot be modified when the DataSource property is set.

You say "when i refresh stuff and getting error that data source is already binded". The "and" implies that there are two different problems, so I need to ask if that is what you meant. Do you mean to say that when you refresh stuff there is a problem (if so then what is the problem) and you are also getting an error?

Normally we let the IDE take care of things like this. You can create a data source and then drag a field from the data source and drop it onto the form.

Why are you re-binding the controls? It is unlikely you need to do that.
