InfoPath Dev

I need to dynamicly create a repeating table based on value of two dropdown.

dropdown1 - event

dropdown2 - number of employee

event will define colums those will display in repeating table (ie. for event1 user should enter name, phone number while for event2 user need to inter name, phone number, address) and number of rows will be defined by value selected in dropdown 2

Then i want to store value of these rows as list items.

Can any one suggest possible solution?

If you only have 2 events, you can create 2 repeating tables and hide the other repeating table depending on what event was selected.  Otherwise, there is no out of box way to create dynamic columns in a repeating table.

Also there is no out of the box method to insert x rows to a repeating table using rules in InfoPath.  Your options are to use qRules, allow the user to insert their own rows, or add the rows yourself via default values and show/hide the rows as necessary using rules.

Thanks Anson for your reply but I have about 20 events now for that I may need to create 20 repeating tables. the number of events will increase after some time. this approach may cause performance issue for InfoPath form. So I was thinking to create these repeating tables dynamically whenever required on form.
