Hi,

 

I am exploring Devforce by converting a small App I developed some time ago. I would like to be able (in loose controls) to enter a product code in a text box and its description should show in linked product combobox, and if the combobox is changed the textbox should show the product code.

 

similarly I would like to do the same for a grid control so that entering a product code shows its description in the adjacent combobox, and also its price in another textbox.

The typical way that this is done is by having a BindingSource that is shared by all or most of the controls on the form.  When the current position in the BindingSource changes, all of the controls that are bound to the BindingSource are updated.  For example, in a large number of the tutorials, the BindingNavigator and the ControlBindingManager use the same BindingSource.

Send a small reproducible case (preferably using IdeaBladeTutorial database) to support@ideablade.com.

The problem was that the Table name and the field name are the same although different case.
