I have a dropdown list and a group of radio buttons on my form.
I need that the appropriate radio button should get automatically checked based on the selection of an item from a dropdown list.
If Item 1 is selected than radiobtn1 should be checked and if Item 2 is selected than radioBtn2 should get checked.
This article covers the basic principle of changing a form field from a dropdown and will get you started:
However, the example is changing a set of text fields from the combo selection. Radio buttons are a little different, but not much. A radio button is turned on when the value of the Radio Button Group is set to the export value of a specific button.
So if you make the export values for the list the same as the export values for the radio buttons, then you can use this code in the Keystroke Script for the combobox
this.getField("RadioGroup").value = event.changeEx;
The "RadioGroup" needs to be changed to the name of your radio button group
Was very helpful.
It took me a while, though, to figure out how to make the export values of the Radio buttons the same as the export values of the list. But got it in the end.
