Hey Pete,

No prob. Glad you had a chance to learn some new things and implement a solution. I ran into the same issues when trying to learn Windows Forms binding. Data binding is usually problemmatic on virtually any platform.

I now try to do more work with the Data Source for modifying data programmatically but there are always times when it might be necessary to modify the data at the Control level.

>>>It is. I don't know why you'd have to do this if you've properly databound those controls. I thought the problem you initially wrote about was because you programmatically changed the value in a control (say, a TextBox.Text) and you needed to use the .WriteValue() for that reason, for one or two controls perhaps.

>>>If you're regularly clearing the values in all your controls by the below methodology (setting all TextBox.Text = ""), then your problem is actually that you shouldn't be doing it that way. Those TextBoxes are bound to a DataTable ... you should be clearing the data in the DataTable row and those empty values will then be shown in your TextBoxes.
