How to write expression for textbox in RDLC report

Hi there,

Once you have open your .rdlc for editing:

1) Right-click the textbox you want to manage.
2) In the context menu, select the Text Box Properties option.
3) When the properties dialog opens, select the Visibility section.
4) Then, select "Show or hide based on expression"
5) Click the "Fx" button to open the Expression Editor.
6) Your formula should start with "=" sign and a bool expression based on the Built-In Fields TotalPages field.

Keep in mind that you are managing that textbox's visible property, if your expression return "true" it will stay visible, therefore, to hide it, your expression must return "false".

Here's an example based on an input parameter:

=Not(CBool(Parameters!VerTasa.Value))

Note: Since the incoming value is the opposite of what's needed, an NOT(...) is included

Cheers!
