如何将文本框文本绑定到xaml中的属性值 [英] How to Bind TextBox Text to Value of Property in xaml

问题描述

我有一个名为TextBoxColumn的自定义类，如下所示

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); }
        }
     ...
}

从XAML创建DataGrid列时:

When creating DataGrid columns from XAML:

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

在XAML词典中，我为此TextBoxColumn定义了单元格模板:

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 -->
</DataTemplate>

如何获取TextBoxColumn的FieldName属性的值并将其绑定到Text属性?
