i have a question. I m using a Tabcontrol having 3 TabPages.
on the Third TabPage i have some textboxes. Some Textboxes are used for inputs and some are for the calculated values.
i.e I Take input for yarn cost per meter and by multiplying its value with total order qty i show the calculated value in other Textbox.
The problem is when i edit a record and the SelectedIndex of TabControl is not TabPage 3 and when i save the record without moving to TabPage 3 i receive an error shows that Input String was not in Correct Format. But when i move to that TabPage i receive no error and record successfully saves. Whereas i have all the textboxes populated by using DataBindings.
What could be the problem.
