Collapse/Toggle SSRS Matrix Group

I had sensed trouble when I want to show the collapse / toggle group in SSRS 2005, but after I finally find the way it works.

The following are easy steps:

• 

if the column group is a group of row like the picture above, then, right click on the group you want to show collapse / toggle and select edit....as in the following figure

• 

*then on the menu tabs 'visibility' select 'hidden' if the initial report view to hide, select the 'textbox' which will be the control. in the case below the textbox control is 'NameAgent'

• 

#if the group is a group of columns, such as the following picture

• 

then the way is the same as above
