Question

I have a simple datagrid which can be sorted by clicking the column header.
When I open the window, datagrid is not sorted. Then, when I click, arrow appears and it’s sorted asc, click again – sorted desc etc. very simple.

What I need to do, is to open window with already sorted datagrid. So arrows (that shows which direction datagrid is sorted) should be always visible. I have to have my datagrid sorted all the time.
How can I do that? I prefer to do that in xaml, but any solution will be great.

BTW. App in .NET4

Answer 1

You can set your sort on the column itself

<DataGrid>
    <DataGrid.Columns>
        <DataGridTextColumn SortMemberPath="Name" SortDirection="Descending" />
    </DataGrid.Columns>
</DataGrid>
