1,ComboBox簡單 綁定
<ComboBox Grid.Row="1" Grid.Column="3" Height="20" HorizontalAlignment="Left" VerticalAlignment="Top" Name="lstSex" Width="100" Margin="5,4,0,0" SelectedIndex="0">
<ComboBoxItem Content="先生" />
<ComboBoxItem Content="女士" />
</ComboBox>
2,ComboBox數據綁定
2.1 xmal
<ComboBox Grid.Row="0" Grid.Column="3" Height="20" HorizontalAlignment="Left" VerticalAlignment="Top" Name="Comb1" Width="100" Margin="5,8,0,0">
</ComboBox>
2.2 數據源
public class Student
{
public string Name
{
set;
get;
}
}
public class Students
{
public List<Student> StudentList
{
set;
get;
}
public List<Student> getStudent()
{
StudentList= new List<Student>
{
new Student(){Name="X1"},
new Student(){Name="X2"},
new Student(){Name="X3"}
};
return StudentList;
}
}
2.2 後臺代碼
private void BindStudent()
{
Comb1.ItemsSource = new Students().getStudent();
Comb1.DisplayMemberPath = "Name";
}
3 ComboBox賦值
3.1 ComboBox的Items處於固定的狀態
Comb1.ItemsSource = new Students().getStudent();
switch (userModel.UserDepartment )
{
case "X1":
this.Comb1 .SelectedIndex =0;
break;
case "X2":
this.Comb1 .SelectedIndex =1;
break;
case "X3":
this.Comb1 .SelectedIndex =2;
break;
}
3.2 當ComboBox的Items時時處於變化的狀態
到數據庫查詢到student.Name,Name可能隨時被修改
foreach(Student item in Comb1.Items)
{
if(item.Name == student.Name)
{
Comb1.SelectedItem = item;
}
}
