Я плохо использую WPF, на самом деле я использую его впервые. Вот почему мне нужна ваша помощь.
У меня есть DataGrid с AutoGeneratingColumn, и я хочу создать некоторый стиль для dataGrid. Но трудно придать этому стиль. И у меня есть флажок, который при проверке генерирует строку с данными stati c.
Это мой код XAML
<DataGrid x:Name="dtgResults" ColumnWidth="*" AutoGeneratingColumn="dataGrid1_AutoGeneratingColumn">
<DataGrid.ColumnHeaderStyle>
<Style TargetType="{x:Type DataGridColumnHeader}">
<Setter Property="FontWeight"
Value="Bold" />
<Setter Property="HorizontalAlignment" Value="Stretch" />
<Setter Property="HorizontalContentAlignment" Value="Center" />
</Style>
</DataGrid.ColumnHeaderStyle>
</DataGrid>
<CheckBox x:Name="chkMistUserDefined" Grid.Column="0" HorizontalAlignment="Right" Click="chkMistUserDefined_Click"/>
<TextBlock Text="Override predicted misfraction" Grid.Column="1" HorizontalAlignment="Left"/>
Это мой код .cs

And this is what I need to do
