Hi,

Thank you for posting.

If a control is bound to a datasource at design-time, you could see the
data binding at the DataBindings part in the Properties Window.

If a control is bound to a datasource at run-time, you could not see the
data binding in the Properties Window.  But you could see the data binding
in your code. For example, the code for binding a TextBox to a field of a
datatable may be the following:

this.textBox1.DataBindings.Add(new System.Windows.Forms.Binding("Text",
this.dataSet11, "Persons.PersonID", true));

Hope this is helpful to you.
If you have any other concerns or need anything else, please don't hesitate
to let me know.

Sincerely,
Linda Liu
