使用C#为DataGrid创建ItemTemplate

Question

这是XAML.我想用C#做同样的事情.

<DataGrid x:Name="myDataGrid">
    <DataGrid.Columns>
        <DataGridTemplateColumn Header="Address">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBox Text="{Binding Path=Address}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

请帮忙.

如果要DataTemplate在代码中创建,则应使用FrameworkElementFactory(msdn).

XAML:

<DataGrid x:Name="myDataGrid" AutoGenerateColumns="False" Loaded="myDataGrid_Loaded">
    <DataGrid.Columns>
        <DataGridTemplateColumn x:Name="templateColumnAddress" Header="Address" />
    </DataGrid.Columns>
</DataGrid>

代码隐藏:

public void myDataGrid_Loaded(object sender, EventArgs e)
{
    FrameworkElementFactory tbHolder = new FrameworkElementFactory(typeof(TextBox));
    tbHolder.SetBinding(TextBox.TextProperty, new Binding("Address"));          
    var dataTemplate = new DataTemplate();
    dataTemplate.VisualTree = tbHolder;
    dataTemplate.DataType = typeof(DataGridTemplateColumn);
    templateColumnAddress.CellTemplate = dataTemplate;
}
