I faced the issue with missing header row for all GridView contols within the app. Pretty much all of the grids have it's own style. Some of GridViews shares GridView header row style. I made some changes on one of the header row styles (some color changes, borders etc, something that should not affect on row visibility) but suddenly, all the GridViews in the app have header row missing.
I went through all GridView controls and set specific property for header row/column visibility but no effect. Any ideas?
Note: recently I updated Telerik dlls to the latest one.Also, I revert changes in the styles to the old one (when it was working fine) but no effect.
