Show Column Names in a Table based on Conditions

[QVUser1]

Hi Team,

I have Table  as listed in the below:

I need to show columns based on multiple conditions:

1. If no Filters are selected  it should  display all Columns
2. If Student is selected , there is no values for Data Column. So it should display only three Columns(Student,Rolno,Marks)

Student	Roll no	Marks	Data
A	1		-
B	2		-
C	3	23	-
D	5	25	-

Use =GetSelectedCount(Student)=0 for the show condition for the Data column.

For the dimension "Data", you can enter an expression in the properties field "Show column if". Try one of these, both should probably work:

=getselectedcount(Student)=0

=count(Data)>0

Thanks for the quick response.

The above expression works only if nothing is selected . but If I select any Student then column Data should not Appear.

It means Hide and show column on multiple conditions

You are saying "if Student is selected, then hide the Data column". So the show-condition for column Data should be False when any number of values in the Student dimension is selected.

If you select one or more values in the dimension Student, the counter getSelectedCount(Student) will reveal how many unique students are selected - if no Student is selected the value is 0.

If no Student value is selected, the expression =getselectedcount(Student)=0 means "if 0=0", and the column will be visible since the statement is True. If two students are selected, the expression will be like "if 2=0" which is of course False, so the column should be hidden.

If this is not the case for you, I think maybe you are entering the expression in the wrong place or that there is something else in your data model affecting this that you haven't said anything about.

Another option is that we have not understaood your requirement, because in your last comment you say "It means Hide and show column on multiple conditions". What do you mean by that?
