Column resizing in wpf datagrid

问题

I am currently developing a WPF software. I am using WPF and am trying to allow the columns to auto size to fit in with the datagrid.

I have used columnwidth="*" which works fine as long as the window is not enclosed within scrollview. If it is in a scroll view then the columns resize really big which causes the datagrid to resize wider off the edge of the screen causing a large amount of scrolling.

Thanks for any help you can provide.

You might try binding your scrollviewer's Width to the ActualWidth of the DataGrid. So on the ScrollViewer put this (assuming your grid is named MyMainGrid):

Width="{Binding ElementName=MyMainGrid, Path=ActualWidth}"
