1.Make a procedure for it

2.Place it in the exististing ON-POPULATE-DETAILS at the end of the code if you a a master/detail contruct plus WHEN-NEW-RECORD-INSTANCE to catch some special cases.

3.Post the Code - do only do a switch of the Canvase (ON/OFF) if necessary.

Place your block on a stacked canvas, put it on the same window and do something like this:

Default would be visible = false (not visible) for the stacked canvas

-- Show View if :xitem and not visible

if :xitem is null and GET_VIEW_PROPERTY('CN_DETAILS', visible) = 'FALSE'

then

 SHOW_VIEW('CN_DETAILS');

 SET_VIEW_PROPERTY('CN_DETAILS', visible, property_true);

else

-- Hide only if necessary

if GET_VIEW_PROPERTY('CN_DETAILS', visible) = 'TRUE'

 HIDE_VIEW('CN_DETAILS');

 SET_VIEW_PROPERTY('CN_DETAILS', visible, property_false);

end if;

end if;

thanks for your reply.

But i have a problem.

I don't need to create another canvas.

I want to put my data block with other data blocks in the same canvas.

What should i do in this case?

You have two options.

1) Loop through the desired block and set all items invisible when the condition is met

2) Make a stacked canvas of the size you need to hide the block during runtime,

when the condition is met to cover the items

If you want a fast and easy solution I would recommend the dynamic canvas solution.

For every problem you need some code for a solution to solve it :)

So you need additional code or and additional canvas. You decision

i am trying the second option.

As i am new with forms, i still have one issue.

where should i add my code?

Is it in the data block trigger 'when new bloc instance'?
