I'm working on a tablix in SSRS 2008 and want my columns to autosize (width only) to their contents. CanGrow only affects height. Is there a property I'm missing or any way to otherwise rig the columns to do this?
I've been trying to do that myself (client side), without success. There is no property that would autosize the column width.
Check out this workaround: http://blog.sharepointalist.com/2009/05/ssrs-column-width-auto-size.html (I haven't tested it)
The best workaround I've found for client side reporting would be to set column's width in code or use multiple columns and show/hide them based on string length condition.
For example, column named AccNum2:
report.DetailSection1.ReportObjects.Item("AccNum2").width = 200
