I want to create a custom control like a picker in Winform. When I select a value of the picker, the other textboxes will be set to the corresponding value. For example, the picker is Product. After selecting a Product, ProductName and ProductPrice can be set into the specified textboxes.

I have an idea to create a custom control that when I add it to the Form, the Textboxes in Form will automatically have a new attribute “picker” added and I can enter a field from Picker into it. . If you have ever worked with GrapeCity’s GcShortCut then you will understand that it is possible. but I really don’t know what to do.

If anyone knows please let me know. Or if you have any other ideas please let me know. thank you very much

I tried looking for results on Google but I can’t think of what the keyword is?
