我有一个名为 FieldViewModel 的 View 模型:
public class FieldViewModel: INotifyPropertyChanged
{
private Field m_field;
public Field FieldData
{
get { return m_field; }
set
{
m_field = value;
NotifyPropertyChanged("FieldData");
}
}
和 Field 类:
public class Field : INotifyPropertyChanged
{
public List<string> SqlTypes
{
get { return Enum.GetNames(typeof(SqlDbType)).ToList(); }
}
private string m_FieldName = null;
public string FieldName
{
get { return m_FieldName; }
set
{
m_FieldName = value;
NotifyPropertyChanged("FieldName");
}
}
private string m_FieldType = null;
public string FieldType
{
get { return m_FieldType; }
set
{
m_FieldType = value;
NotifyPropertyChanged("FieldType");
}
}
private bool m_NullAllow = false;
public bool NullAllow
{
get { return m_NullAllow; }
set
{
m_NullAllow = value;
NotifyPropertyChanged("NullAllowsChecked");
}
}
#region INotifyPropertyChanged
public event PropertyChangedEventHandler PropertyChanged;
private void NotifyPropertyChanged(String propertyName = "")
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
#endregion
}
Xaml:
<ComboBox ItemsSource="{Binding FieldData.SqlTypes}" SelectionChanged="cmbField_Selected" Width="20" Height="20" Margin="5,5,0,5" VerticalAlignment="Top" HorizontalAlignment="Left"/>
<TextBox Width="120" Height="20" Text="{Binding FieldType}" Margin="0,5" VerticalAlignment="Top" HorizontalAlignment="Left"/>
现在在 xaml 中我想绑定(bind) Field 类的变量但是我看不到它们
我尝试了一些方法,但没有任何效果,如果我将 Field 类的变量放在 FieldViewModel 中,效果很好。
感谢您的帮助。
最佳答案
这是一个对我有用的例子:
<Window x:Class="DataGridExample.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<DataGrid x:Name="czesciTable" ItemsSource="{Binding model.list}"
AutoGenerateColumns="False"
CanUserAddRows="False">
<DataGrid.Columns>
<DataGridTemplateColumn>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding}"/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
</Grid>
View 模型:
public class ViewModel
{
public Model model { get; set; }
public ViewModel()
{
model = new Model();
}
}
和模型:
public class Model
{
public List<String> list { get; set; }
public Model()
{
list = new List<string>();
list.Add("Item1");
list.Add("Item2");
list.Add("Item3");
}
}
结果:
或组合框:
<ComboBox ItemsSource="{Binding model.list}" VerticalAlignment="Top"/>
