I have a combo box called CustomerID with which i use to select the customer i want.If i select a cutsomer that does not exist, then
the folloiwng message appears:
" The text you entered isnt an item in the list.Select an item from the list or enter text that matches one of the listed items"
This creates me enormous problems, since the combo box stays with the name or number i have seletced and that is not in the list.
When i click on some other control for example to exit the database, then the database get stuck.
can you help me imrpove my combo box ? I want , when the user chooser a wrong or non existen customer, to clear the combo box
in such a way that i have no further problems with freezing the database.How can i achieve that?
