WPF DataGrid: how do I stop auto scrolling when a cell is clicked?

Question

Problem:
If my DataGrid is not entirely visible (horizontal & vertical scrollbars are showing) and I click on one of my cells that is partially visible, the grid auto-scrolls to bring that cell into view. I don't want this to happen. I've tried playing around with RequestBringIntoView, like this:

private void DataGrid_RequestBringIntoView(object sender, RequestBringIntoViewEventArgs e)
{
    e.Handled = true;
}

But that does nothing.

Things I've tried:

• My cells are custom UserControls; I tried putting an event handler for RequestBringIntoView on all UserControls that make up my cells, and tried handling the event, thinking that maybe I wasn't doing enough by just handling RequestBringIntoView on the DataGrid itself. This did not work.
• Hosted the DataGrid inside of a ScrollViewer, and handled the ScrollViewer's RequestBringIntoView event. This actually works, and stops the auto-scrolling behavior, but in my case hosting a DataGrid inside of a ScrollViewer is not at all desirable, so I need to come up with a different solution.

I'm not sure how to stop this behavior, any ideas?

Answer 1

Define an EventSetter in the DataGrid.RowStyle to call a handler that prevents the row from being brought into view:

XAML

<DataGrid>
    <DataGrid.RowStyle>
        <Style TargetType="{x:Type DataGridRow}">  
            <EventSetter Event="Control.RequestBringIntoView" Handler="DataGrid_Documents_RequestBringIntoView"  />
        </Style>
    </DataGrid.RowStyle>
</DataGrid>

Handler

private void DataGrid_Documents_RequestBringIntoView(object sender, RequestBringIntoViewEventArgs e)
{
    e.Handled = true;      
}
