I've created dynamic table based on XML schema. This will have a lot of dynamic rows which will be filled with data from XML file. Also in one cell of the tablle I added radio button. How can i combine this radio buttons into the one RadioButtonList?
The radioButtonList must contain radiobuttons in the same context (at the same level in the hierarchy). If you have a single radiobutton in each row of a table then they are not in the same context. You can make them exclusive but you will have to write your own code to do so....and it will be complicated code!
Typically the fields will already exist and are hidden (excluded from layout) or if it is a case or reapting data structures you woudl wrap your fields in a repeating subform and the new objects will be created to hold all data. There are examples of all of this shipped with the Designer. Check thme out in you install directory EN/Forms/Samples. I would pay particular attention to the dynamic samples.
