If you want to let the last column in a datagrid fill the datagrid, you should use the first columns width to auto en set the last column width to * and specify minimum widths for the columns:
<DataGrid Name="subsysteemSettingsDataGrid" AutoGenerateColumns="False" HeadersVisibility="Column" HorizontalAlignment="Stretch" Margin="10" HorizontalGridLinesBrush="LightGray" VerticalGridLinesBrush="LightGray" HorizontalScrollBarVisibility="Disabled" CanUserAddRows="False" BorderBrush="#FF8C8E94" SelectionUnit="FullRow" CellStyle="{StaticResource SelectedSubDataGridCellStyle}"> <DataGrid.Columns> <DataGridTextColumn Header="Name" Binding="{Binding Path=Name, Mode=TwoWay,
UpdateSourceTrigger=PropertyChanged}" MinWidth="150" Width="Auto" /> <DataGridTextColumn Header="Value" Binding="{Binding Path=Value, Mode=TwoWay,
UpdateSourceTrigger=PropertyChanged}" MinWidth="200" Width="*" /> </DataGrid.Columns> </DataGrid>
De screendump below shows the last column stretched to the width of the datagrid
I want to set the window SizeToContent=”Width”. The datagrid strech the window to the full size of screen if i set the last column to Width=”*”. The window has correct size if columns in datagrid set to Auto, but the last is not stretch.
I have no solution found for this problem…
