How do I adjust overall width of rdlc report when some columns are hidden?
Problem:Lets say that I have 10 columns to view report and I want to hide 3 of these columns at runtime based on the value of parameter which the user would select. This can be easily done by setting the column visibility of each of these 3 columns based on the value of the aforesaid parameter. It's perfectly fine up till here.

The problem is when the report shows up (with 3 columns hidden) the remaining 7 columns take up the place of the hidden columns and as a result the overall width of the table reduces accordingly. I do not want this to happen. i.e. I want the table width to remain constant.That is to say the remaining columns width should somehow be able to expand so that the original overall width of the table remains same.Is this possible to achieve?
