In one of our reports we were using List Control to show information related to Account(Business) and its related Task and Appointments. The information was being shown in three different Tablix respectively and if there were no Task and Appointments then we were hiding the Account (Business) Tablix and Rectangle by setting their Hidden Property.
Fig. Three Tablix inside the List Control.
However after running the report we realized that Rectangles although were hiding properly but were still consuming the white space. Because of this we had blank white spaces in our report.
So to display the reports properly we had to set the Hidden Property of the Row also.
Select the Row and Right click it.
Select Row Visibility and set its property using the same expression used for Rectangle’s Visiblity property.
After making this change report started showing up properly.
