c# - 如何检查按钮单击事件上的 DataGridCheckBoxColumn 复选框

Question

如何在单击按钮时检查 DataGridCheckBoxColumn。因此，当我触发按钮单击事件时，我希望检查 DataGridCheckBoxColumn。

 private void loadCheckBoxColumn()
    {
        MedicationDatagrid.Columns.Add( new DataGridCheckBoxColumn
         {
            Header = "Selected",
            Binding = new Binding( "checkBox" )

           } );
    }

按钮点击事件:

 private void btnchecked_Click( object sender, RoutedEventArgs e )
        {

        AwaitingMeds checkedItem = new AwaitingMeds();
        List<AwaitingMeds> awaitingMedslist = MedicationDatagrid.ItemsSource as                   List<AwaitingMeds>;
        buttonClickCheckedUnChecked();
        if( !( ( AwaitingMeds )MedicationDatagrid.SelectedItem == null ) )
        {
            checkedItem.checkBox = true;

        }

    }

buttonClickCheckedUnChecked:

   private void buttonClickCheckedUnChecked()
    {

        AwaitingMeds checkedItem = new AwaitingMeds();

        if( checkedItem.checkBox == true )
        {


            btnunChecked.Visibility = Visibility.Visible;
        }
        else
        {

            btnunChecked.Visibility = Visibility.Collapsed;
        }
    }

我更愿意在列模板中使用普通的 WPF-CheckBox。然后简单地将 CheckBox 绑定(bind)到您的 ItemSource 并完成它。

<DataGridTemplateColumn Header="Ist aktiv" IsReadOnly="True">
    <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <CheckBox IsChecked="{Binding IsActiveBool}" Click="myIsActiveCheckBox_Click" />
        </DataTemplate>
    </DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
