We use TMS Web Core 2.7.1.0. In the attached project
TestWebStringGridVerticalScrollbar.zip (14.5 KB)
the vertical scrollbar of a TWebStringGrid is truncated which IMHO should not be the case. You can fix this, by replacing #FIXgrid1tbl by #grid1tbl in Unit1.html. This actually fixes the DOM of the table generated by the TWebStringGrid.
You map the grid on a span and table with undefined height. As such, the table height will automatically adapt to the nr. of rows in the grid.
When you map the grid on your HTML elements, it is under control of this HTML & CSS how it will be rendered.
