[WPF]DataGridメモ

新しい行を表示しないようにするには

[XAML]

<DataGrid x:Name="dgExamList" CanUserAddRows="False">

コードビハインドで列の書式を設定するには

[XAML]

<DataGridTextColumn x:Name="clDate" Binding="{Binding exam_day}"/>

[C#]

clDate.Binding.StringFormat = "yyyy/MM/dd";

DataTableをDataGridで使い、フィルターをかける
Make use of filtering of DataGrid with DataTable

[XAML]

<DataGrid x:Name="dgExamList" ItemsSource="{Binding}" AutoGenerateColumns="False">

[C#]

public partial class ExamList : Window
{
  private DataTable exam_list = new DataTable();
  private BindingListCollectionView cv;

  public ExamList()
  {
    InitializeComponent();

    //ここにexam_listを生成するコード。Generate exam_list

    cv = new BindingListCollectionView(exam_list.DefaultView);
    dgExamList.DataContext = cv;

    filterGridView(filterStr.BlankDraft);
  }

  private enum filterStr { ShowAll, BlankDraft, Done, Checked, Canceled };
  private void filterGridView(filterStr fs)
  {
     switch (fs)
     {
       case filterStr.ShowAll:
         cv.CustomFilter = null;
         break;
       case filterStr.BlankDraft:
         cv.CustomFilter = "exam_status < 2";
         break;
       case filterStr.Done:
         cv.CustomFilter = "exam_status = 2";
         break;
       case filterStr.Checked:
         cv.CustomFilter = "exam_status = 3";
         break;
       case filterStr.Canceled:
         cv.CustomFilter = "exam_status = 9";
         break;
     }
  }
}
