wpf 中DataGrid 控件的样式设置及使用

本次要实现的效果为：

这个DataGrid需要绑定一个集合对象，所以要先定义一个Experience类，包含三个字段

/// <summary>

/// 定义工作经历类

/// </summary>

public class Experience

{

/// <summary>

/// 获取或设置工作的起始时间

/// </summary>

public string Start { get; set; }

/// <summary>

/// 获取或设置工作的结束时间

/// </summary>

public string End { get; set; }

/// <summary>

/// 获取或设置工作地点

/// </summary>

public string Location { get; set; }

}

接下来在 Window_Loaded(object sender, RoutedEventArgs e) 时间中设置DataGrid的数据源

private void Window_Loaded(object sender, RoutedEventArgs e)
{
            List<Experience> list = new List<Experience>()
            {
                new Experience(){ Start="1990-01-01", End="1991-01-01", Location="北京"},
                new Experience(){ Start="1991-01-01", End="1992-01-01", Location="郑州"},
                new Experience(){ Start="1992-01-01", End="1993-01-01", Location="上海"},
                new Experience(){ Start="1993-01-01", End="1994-01-01", Location="洛阳"},
                new Experience(){ Start="1994-01-01", End="1995-01-01", Location="天津"},
                new Experience(){ Start="1995-01-01", End="1996-01-01", Location="大连"},
            };

//把XAML中DataGrid的ItemSource绑定到List对象上去
            this.grid_user.ItemsSource = list;   
       
}

接下来看一下XAML中是怎样创建DataGrid

<Grid>
                        <Grid.RowDefinitions>
                            <RowDefinition Height="30"/>
                            <RowDefinition />
                        </Grid.RowDefinitions>
                        <Label Background="#82c772"
                               Content="个人经历"
                               Padding="20,5,0,0"
                               FontSize="14"
                               Foreground="White" />
                        <DataGrid Name="grid_saffer"
                                  Grid.Row="1"
                                  IsReadOnly="True"
                                  AlternationCount="2"
                                  AutoGenerateColumns="true" >
                            <DataGrid.Columns>
                                <DataGridTextColumn Header="开始时间"
                                                    Width="1*"
                                                    Binding="{Binding start}" />
                                <DataGridTextColumn Header="结束时间"
                                                    Width="1*"
                                                    Binding="{Binding end}" />
                                <DataGridTextColumn Header="地点"
                                                    Width="1*"
                                                    Binding="{Binding location}" />
                            </DataGrid.Columns>
                        </DataGrid>
                    </Grid>

这里有几个属性需要说一下

AlternationCount="2"   表示两行交替显示背景色。如果不设置此属性则显示效果为：

AutoGenerateColumns="False"   表示不让DataGrid自动生成列。如果设置成true，则效果如下： 多出了不需要的列

HeadersVisibility="Column" 设置此属性为只显示列标题单元格，行标题不显示。如果不设置此属性则效果为：

到此为止还没有真正为DataGrid添加任何样式，接下来展示样式代码

建议：样式代码比较多，最好是先复制到自己项目中看效果，然后再细看样式的实现。 在此，内容已介绍完，如有疑问请留言。
