How to place a long Grid in a WPF Layout Container?

Question

When I place a Datagrid in a WPF Grid Layout container, the datagrid lengthens the Grid Layout. I want it to occupy only the space available on screen.

Answer 1

Make sure your Grid.ColumnDefinition or Grid.RowDefinition's Width or Height is not set to Auto. If you set it to a fixed size or a star size then the row/column should not resize.

If you're still having problems a code sample would be useful.

Answer 2

您应该将Datagrid放入ScrollViewer ，然后将ScrollViewer放入Grid单元。

Answer 3

the grid is placed inside a tabitem. I tried the scrollviewer. but the only thing that happens: the scrollviewer gets as large as the too long datagrid.

as the tabitem can vary in height, I would rather not like to specify a fixed height for the grid.
