The setter is intentionally not exposed. Here is some general reasoning - If we allow setting this property , we should provide some editing functionality to the column . And for the hyperlink there is not a standard editor - one would like to edit the url , other would like to edit the description etc. Since we can not cover the general case and yet the column is purposed for navigation and not editing we could not allow setting of this property .
For such scenario either your approach (inheriting GridViewBoundColumnBase ) or retemplating the GridViewDataColumn are recommended.
