How to control report elements programmatic

Question

I am making report in report builder 3.0 in table matrix. Now requirement arise that they hide and unhide from Custom Dialog. Now requirement is such that column should shrink auto if all columns are there and columns should be expand if columns are less.

How can I achieve this.  

Answer 1

If you want to hide a column you can do it by setting the hidden expression and a toggle button.

Ex: you can make one column visible (from hidden) and another hidden (from visible) with one click on the toggle button. This can be done by setting the same toggle button for two columns and set different hidden value (one true and one false).

Answer 2

This is not my problem. My problem is as for example I have there 7 columns and at time of report generating I select only 5 columns to visible than I need to adjust width of the columns propositional. 

Answer 3

Answer 4

I am not telling to set the size or location by expression but i wanted to know by code-behind. It is possible
