NoDataBehavior

rbuser

This is surely a stupid question but here it is anyway.

How can I access the NoDataBehavior from and End-user point of view ? In
other words, how can my end-users change this property while they create
reports ?

Thanks!

Hi Steve,

The end user designer does not support changing the NoDataBehaviors
property. There is a RAP OnNoData event that you can code to handle what
happens when there is no data.

As an alternative, you could add a designer menu option that shows a form so
that they can set this property. Then your users may want to code the
Report.OnNoData event in RAP to be able to fully use this property, such as
they want to change the text that is displayed for the report when there is
no data. You could also build that into the menu where you create the event
handler in code in RAP or in Delphi code. That way you could have a form
that would let them specify the text that they want to show and you could,
behind the scenes in code, create the draw command or change the dialog text
to what they specified in your custom form.

To add a menu option, there is a merge menu property on the designer. See
the help file for info on the groups numbers in order to add to the menu.
You could also directly manipulate the menu property on the designer at
runtime to add a menu item if you do not want to use the merge menu feature.

If you want to create a RAP event handler in code so your users won't have
to mess with coding, there is an example of that at the end of the installed
RAP demos.
