Silverlight中的DataGrid绑定数据

首先写一个类：

public class Employee

{

public string FirstName { get; set; }

public string LastName { get; set; }

public decimal Salary { get; set; }

public DateTime StartDate { get; set; }

public bool IsVested { get; set; }

public string Gender { get; set; }

}

接着再写一个类，用于DataGrid性别列的下拉框。

public class Genders

{

public List<String> GenderList

{

get

{

return new List<String> { "Male", "Female" };

}

}

}

加入一个名称空间：

xmlns :local="clr-namespace:DataGrid_cs"

然后声明一个属性引用：

<UserControl.Resources>

<local:Genders x:Key="genderList"></local:Genders>

</UserControl.Resources>

编写DataGrid代码：

<data:DataGrid x:Name="grdDisplay"

IsReadOnly="False"

AutoGenerateColumns="False"

RowBackground="Beige"

AlternatingRowBackground="BlanchedAlmond"

ColumnWidth="100"

GridLinesVisibility="Horizontal"

HorizontalGridLinesBrush="Blue"

HeadersVisibility="Column"

Margin="0,50,0,0"

>

<data:DataGrid.Columns>

<data:DataGridTextColumn Header="First Name" CanUserSort="False" Binding="{Binding FirstName}" />

<data:DataGridTextColumn Header="Last Name" Binding="{Binding LastName}" />

<data:DataGridTextColumn Header="Salary" Binding="{Binding Salary}" />

<data:DataGridCheckBoxColumn Header="Is Vested" Binding="{Binding IsVested}" />

<data:DataGridTemplateColumn Header="Start Date" SortMemberPath="StartDate">

<data:DataGridTemplateColumn.CellTemplate>

<DataTemplate>

<TextBlock Text="{Binding Path=StartDate}" />

</DataTemplate>

</data:DataGridTemplateColumn.CellTemplate>

</data:DataGridTemplateColumn>

<data:DataGridTemplateColumn Header="Gender" SortMemberPath="Gender">

<data:DataGridTemplateColumn.CellTemplate>

<DataTemplate>

<TextBlock Text="{Binding Path=Gender}" />

</DataTemplate>

</data:DataGridTemplateColumn.CellTemplate>

<data:DataGridTemplateColumn.CellEditingTemplate>

<DataTemplate>

<ComboBox Loaded="ComboBox_Loaded" SelectedItem="{Binding Path=Gender, Mode=TwoWay}" ItemsSource="{Binding GenderList, Source={StaticResource genderList}}"></ComboBox>

</DataTemplate>

</data:DataGridTemplateColumn.CellEditingTemplate>

</data:DataGridTemplateColumn>

</data:DataGrid.Columns>

</data:DataGrid>

最后写后台代码：

public Page()

{

InitializeComponent();

List<Employee> employeelist = new List<Employee>();

employeelist.Add(new Employee { FirstName = "Tom", LastName = "Smith", Salary = 50000, StartDate = new DateTime(2006, 10, 3), IsVested = true, Gender = "Male" });

employeelist.Add(new Employee { FirstName = "Sue", LastName = "Smith", Salary = 45000, StartDate = new DateTime(2006, 10, 4), IsVested = true, Gender = "Female" });

employeelist.Add(new Employee { FirstName = "Sharon", LastName = "Smith", Salary = 79000, StartDate = new DateTime(2006, 10, 5), IsVested = false, Gender = "Female" });

employeelist.Add(new Employee { FirstName = "Joe", LastName = "Smith", Salary = 55000, StartDate = new DateTime(2006, 10, 6), IsVested = true, Gender = "Male" });

employeelist.Add(new Employee { FirstName = "John", LastName = "Smith", Salary = 60000, StartDate = new DateTime(2006, 10, 7), IsVested = false, Gender = "Male" });

employeelist.Add(new Employee { FirstName = "Amy", LastName = "Smith", Salary = 65000, StartDate = new DateTime(2006, 10, 8), IsVested = true, Gender = "Female" });

employeelist.Add(new Employee { FirstName = "Kristi", LastName = "Smith", Salary = 150000, StartDate = new DateTime(2006, 10, 9), IsVested = false, Gender = "Female" });

grdDisplay.ItemsSource = employeelist;

}

private void ComboBox_Loaded(object sender, System.Windows.RoutedEventArgs e)

{

((ComboBox)sender).IsDropDownOpen = true;

}
