WPF DataGrid绑定及列居中

基本的数据绑定

　　把集合的字段（属性）绑定在DataGrid的Binding属性就能将数据绑定列表

   public class CashItem {
       public int Value { get; set; }
       public int Count { get; set; }
       public int Amount { get { return Value * Count; } }
    }

            var items = new List<CashItem>() {
                new CashItem{Value=100,Count=23},
                new CashItem{Value=50,Count=10},
                new CashItem{Value=20,Count=5},
                new CashItem{Value=10,Count=11}
            };
            this.Cassetters.ItemsSource = items;

  <DataGrid Name="Cassetters" HeadersVisibility="Column" GridLinesVisibility="Horizontal" AutoGenerateColumns="False">
      <DataGrid.Columns>
          <DataGridTextColumn Header="面值" Width="80" Binding="{Binding Value}">
          </DataGridTextColumn>
          <DataGridTextColumn Header="张数" Width="80" Binding="{Binding Count}"></DataGridTextColumn>
          <DataGridTextColumn Header="金额" Width="*" Binding="{Binding Amount}"></DataGridTextColumn>
      </DataGrid.Columns>
  </DataGrid>

DataGrid列居中

　　列居中需要使用到了模板，但是列头的居中需要自己定义样式，数据的绑定方式和之前的一样也是通过Binding属性

  <DataGrid Name="Cassetters" HeadersVisibility="Column" GridLinesVisibility="Horizontal" AutoGenerateColumns="False">
      <DataGrid.Columns>
          <DataGridTextColumn Header="面值" Width="50" Binding="{Binding Value}">
          </DataGridTextColumn>
          <DataGridTextColumn Header="张数" Width="50" Binding="{Binding Count}"></DataGridTextColumn>
          <DataGridTextColumn Header="金额" Width="50" Binding="{Binding Amount}"></DataGridTextColumn>
          <DataGridTemplateColumn  Header="模板列" Width="*">
              <DataGridTemplateColumn.HeaderStyle>
                  <Style TargetType="DataGridColumnHeader">
                      <Setter Property="HorizontalContentAlignment" Value="Center"></Setter>
                  </Style>
              </DataGridTemplateColumn.HeaderStyle>
              <DataGridTemplateColumn.CellTemplate>
                  <DataTemplate>
                      <TextBlock HorizontalAlignment="Center" Text="{Binding Amount}"></TextBlock>
                  </DataTemplate>
              </DataGridTemplateColumn.CellTemplate>
          </DataGridTemplateColumn>
      </DataGrid.Columns>
  </DataGrid>
