How to Bind property to Value of Property in xaml

Question

I have a custom class called TextBoxColumn as Follows

public class TextBoxColumn : DataGridTemplateColumn
{
    public static readonly DependencyProperty FieldNameProperty = DependencyProperty.Register("FieldName", typeof(string), typeof(TextBoxColumn), new PropertyMetadata(""));
    public string FieldName
    {
        get { return (string)GetValue(FieldNameProperty); }
        set { SetValue(FieldNameProperty, value); }
    }
}

When creating DataGrid columns from XAML:

<DataGrid>
    <DataGrid.Columns>
        <local:TextBoxControl FieldName="FirstName"/>
        <local:TextBoxControl FieldName="LastName"/>
    </DataGrid.Columns>
</DataGrid>

In XAML Dictionary, I have defined the Cell Template for this TextBoxColumn:

<DataTemplate x:Key="TextBoxColumn_CellTemplate">
    <TextBox Text="{Binding FieldName}"/> <!-- Here is the problem, if I give FirstName instead of FieldName, it works fine -->
</DataTemplate>`

How to get the value of FieldName property of TextBoxColumn and Bind it to Text property? How can I achieve it without C# code?

Answer 1

给TextBoxColumn控件命名，并尝试按元素名称绑定它的属性

<TextBox Text="{Binding ElementName=txtBoxCol, Path=FieldName}"></TextBox>

Answer 2

没有代码，您将无法做任何事情，没有办法绑定绑定的属性（在这种情况下，您希望Binding.Path成为FieldName ）。
