I tried to set the grid height in percents and it's doesn't effect?
how can I do it? I want it to looks good in pc and laptop and I don't want to have 2 vertical scrollbar (one for the window and one for the grid)/ i want only for the grid.
Please check out the article below that described how to make the Grid widget take the available height. The grid in the example would also resize when the window is resized.
