I have a small problem, so I need your help to solve it.
I have a parameter in which I have disabled multi-selection. But I want to add a "select all" default value to it. I don't found how can I do this without multi-values (check-box).
I want to do this because I have a large parameter list of 1000 values, and it's not practical to use check-box in this case.
I have tried to add a specify default value with the same dataset I used for available values, but it doesn't work. This way just return the first value of my query.
Is it possible to do what i want?
Thanks for your help.
