Add empty item to user variable combobox

Hi,
we are using a variable to allow the user to filter the report output. The content of the variable is provided by a datasource (category with name and id). Everything works fine, but we found no possibility to implement "show all categories". So the question is: is it possible to programmatically add an empty item to the combobox of the variable?

Hello,
Unfortunately, it is not possible for variable with values from datasource.
Please try to add the additional boolean variable for show all records -

Hi,
I know this, but we have 5 variables, if we now have to add 5 addional checkboxes, there is no room left for the report.

Hello.
As a way you could set the type of the variable to List. Then it will be possible to make multiple selection.
You could get more information in the
Using variables to output lists section of the
Dynamic SQL queries article in our Blog.
You could also try to use next option:
Code: Select all
StiOptions.Viewer.RequestFromUserElementsPerColumn = 5;
Thank you.
