Hi All -

I was wondering what property resets a value of a text item to NULL.� For instance, I have a radio button that when clicked, enables a text item box for input.� When the radio button in the group is changed, any value that the user entered is grayed out, however, that value can still be passed to my report.� I want the property to wipe out the entry when the user selects a different radio button.� I figure that it is probably the property�QUERYABLE ,�but I am not sure.� Conceal Data property is not what I am looking for.� If there is no direct property, is there a round-about way that I can create the desired effect programmatically?� Thank you!

Hi,
Make use of When-radio-changed trigger and set the value of the item to NULL whenver the radio button selection is changed by user.

Himanshu -

What is the syntax for that?

set_item_property('item_name', ? , NULL)

I will continue looking in the interm. Thank you!

Himanshu -

Thank you!

I actually used the following code, because even though I had set the UPDATEABLE property to TRUE in the property palette, I still had to set it programmatically because I received the 'Item is protected against updates' error message at run-time. I think this was due to the properties of the block and not the item itself.

set_block_property('block_name', update_allowed,
property_true);
:block_name.item_name := '';

Best Regards,
Steve
