>>Hi all, I need a bit of help understanding why a call to Dataset.Haschanges() returns false. I have a form with several textboxes bound to a Dataset. I create the bindings thus:
>>
>>this.txtFirstName.DataBindings.Add("Text",this.dsNames,"AFieldName");
>>
>>
>>and so on for the other textboxes. Here is the Gotcha !, if I manually change any of the textboxes values by typing , the call to "HasChanges()" correctly returns true, But ! , if I set the values in code e.g.

>>this..txtFirstName.Text = "";
