It shows what I get at design and runtime. All setting are created at design time. Yesterday, the column headers (text and grey cells disappeared in design and runtime and I do use begin/end update. I have not seen this with any other grid, however this is only my second FireMonkey app.
In TAdvStringGrid at design time I am able to use the property "columnheader" and to set it. I bought FMX Grids for XE4 (within package) too. There I am not able to detect a property "columnheader". No explanation for this anywhere. How, please, am I supposed to set the headers? Only by code lines? If so, I am eager to learn why.
