xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
xmlns:WpfToolkit="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit"
1. WpfToolkit:DataGrid在TableView.xaml中定义如下
<WpfToolkit:DataGrid x:Name="PlotViewDataGrid"
ItemsSource="{Binding DataGridSource, Mode=TwoWay}" IsReadOnly="True" SelectedItem="{Binding DataGridSelected}"
AutoGenerateColumns="True" AutoGeneratedColumns="PlotViewDataGrid_AutoGeneratedColumns"
Width="685" RowHeight="25" Margin="0" CanUserResizeRows="True" SelectionMode="Single"
SelectedIndex="{Binding DataGridSelectedIndex, Mode=TwoWay}" Grid.Row="0">
<i:Interaction.Triggers>
<i:EventTrigger EventName="SelectionChanged">
<i:InvokeCommandAction Command="{Binding GetSelectCommand}"
CommandParameter="{Binding SelectedItem,ElementName=PlotViewDataGrid}" />
</i:EventTrigger>
<i:EventTrigger EventName="MouseDoubleClick">
<i:InvokeCommandAction Command="{Binding DataGridDoubleClickCommand}"
CommandParameter="{Binding SelectedItem,ElementName=PlotViewDataGrid}" />
</i:EventTrigger>
</i:Interaction.Triggers>
<WpfToolkit:DataGrid.RowStyle>
<Style TargetType="{x:Type WpfToolkit:DataGridRow}">
<Setter Property="Background" Value="Red" />
</Style>
</WpfToolkit:DataGrid.RowStyle>
</WpfToolkit:DataGrid>
1.在TableView.xmal.cs文件中PlotViewDataGrid_AutoGeneratedColumns函数可以改变列宽
private void PlotViewDataGrid_AutoGeneratedColumns(object sender, EventArgs e) {
double dgwidth = this.PlotViewDataGrid.Width;
int columnWidth = this.PlotViewDataGrid.Columns.Count;
this.PlotViewDataGrid.HorizontalContentAlignment = (HorizontalAlignment)1;
for (int i = 0; i < this.PlotViewDataGrid.Columns.Count; i++)
{
this.PlotViewDataGrid.Columns[i].Width = new Microsoft.Windows.Controls.DataGridLength(dgwidth / columnWidth);
}
}
2.在TableViewModel.cs文件中
#region DataGridDoubleClickCommand
RelayCommand<object> dataGridDoubleClickCommand = null;
public ICommand DataGridDoubleClickCommand
{
get
{
if (dataGridDoubleClickCommand == null)
{
dataGridDoubleClickCommand = new RelayCommand<object>((p) => OnDataGridDoubleClickCommand(p), (p) => CanDataGridDoubleClickCommand(p));
} return dataGridDoubleClickCommand;
}
} private bool CanDataGridDoubleClickCommand(object p)
{
return true;
} private void OnDataGridDoubleClickCommand(object p)
{
DataGridDoubleClickHandle(p);
}
#endregion
3.DataGrid风格自定义
<WpfToolkit:DataGrid.RowStyle>
<Style TargetType="{x:Type WpfToolkit:DataGridRow}">
<Setter Property="Background" Value="Red" />
</Style>
</WpfToolkit:DataGrid.RowStyle>
4.CanUserResizeRows="True"允许用户调整行高
其他参考内容如下：
（1）自动生成列

--><DataGrid AutoGenerateColumns="True" Name="datagrid" CanUserAddRows="False" MouseDoubleClick="datagrid_MouseDoubleClick"/>
2）取消自动生成列，手动绑定到相应字段

http://www.CodeHighlighter.com/
--><DataGrid AutoGenerateColumns="False" Name="datagrid" CanUserAddRows="False" MouseDoubleClick="datagrid_MouseDoubleClick">
<DataGrid.Columns>
<DataGridTextColumn Header="编号" Binding="{Binding ID}"></DataGridTextColumn>
<DataGridTextColumn Header="公司" Binding="{Binding CompanyName}"></DataGridTextColumn>
<DataGridTextColumn Header="固定资产" Binding="{Binding FixedAssets}" Width ="*"></DataGridTextColumn>
</DataGrid.Columns>
</DataGrid>
最后一列设置Width ="*"是为了取消空白列。
（3）后台代码

-->privatevoid Window_Loaded(object sender, RoutedEventArgs e)
{
datagrid.ItemsSource = AccessDAL.OleDbHelper.ExecuteDataTable("SELECT * from Customers").DefaultView;
}
//双击DataGrid，显示相应信息
privatevoid datagrid_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
DataRowView row = datagrid.SelectedItem as DataRowView;
MessageBox.Show(row["id"].ToString());
}
//如果绑定到对象集合，如ObservableCollection<Employee>，代码如下：
ObservableCollection<Employee> col;
public EmployeeManage()
{
InitializeComponent();
col =new ObservableCollection<Employee>();
col.Add(new Employee() { Id =, Name ="Jim", Salary =2500.50f });
col.Add(new Employee() { Id =, Name ="John", Salary =2600.50f });
datagrid.ItemsSource = col;
}
privatevoid datagrid_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
Employee emp=datagrid.SelectedItem as Employee;
MessageBox.Show(emp.Id.ToString());
}
（4）删除选中的多行数据

{
for (int i = datagrid.SelectedItems.Count -; i >=; i--)
{
Good good = datagrid.SelectedItems[i] as Good;
goods.Remove(good);
}
}
