Hi guys, I succeed to make the 3 dropdownlist to depend on each other and show results. the 3 dropdownlist are in the same column called product. But I want to make the selected data to be saved to 3 other hiding columns type text box in the doc type same form. I am not able to save the selected data in before save in code behind of custom form controls.
How Can I put those data to this specific columns in the same form?
Hi Rafik, you can override GetOtherValues method in your form control to return values for other columns of the form. Please, see the example in our documentation for more details - Example - Developing custom form controls.
