Calendar object expression

[dzmitry_shmurye]

There is simple calendar object and I have to use field with dates there.

I need to restrict the list of dates are available for selection.

Is it possible to write such expression to restrict the list of possible dates when we use a field? (AJAX)

In other words I need to get something like that, but using a field instead of variables:

When I try to write the expression I get the following:

- When nothing is selected:

- One date is selected:

Simple example in attachment.

If anybody has any ideas, please help !

Thanks in advance!

I think you must use variables. Like vDateFrom & vDateTo.

After setting the dates in the calendar and assigning values to the variables, you need to activate from in the date field. You can do this with the button.

Unfortunately, I can't use variables because it cause some integration issues for me. I must use only fields.

Any ideas?

"because it cause some integration issues for me." - it's interesting.

In my app it works. But my Date (ДАТА) is a primary key in calendar. Maybe problem in your "Date".

Can you add a master calendar in your app? I can share if you do not mind.

I need to use single value as selected item. Also, if I select one date in the calendar I need to see all possible values to change selection, but this list should be restricted by condition, for example if I have 2 calendars (Date From and Date To), users shouldn't be able to see Date To dates are later than selected Date From.

NOTE!!! It should look properly in AJAX. (see my first picture.)

I'm afraid that you still need to use variables. When using variables, the period border option is available.
