                        </DataGrid.Columns>                    
                    </DataGrid>

Is there some way to put these events in the row ?

I am trying to use this code

<Style TargetType="{x:Type DataGridRow}">
    <MultiTrigger>
        <MultiTrigger.Conditions>
            <Condition Property="local:HideShow.Somefunction" Value="False"/>
            <Condition Property="IsFocused" Value="True"/>
        </MultiTrigger.Conditions>
    </MultiTrigger>
</Style>

But it didn't work as well

Answer 1

I finally realized how to do that Jus need to use EventSetter instead of triggers

as the code bellow

<EventSetter Event="MouseEnter" Handler="Row_MouseEnter"/>
