我有一个数据网格,我已经绑定到SqlDataApter.如果我使用DataTextColumn为网格设置XAML,如下面的代码所示,它可以很好地工作

<DataGrid AutoGenerateColumns="False" HorizontalAlignment="Left" Margin="27,42,0,0" Name="dataGrid1" VerticalAlignment="Top"  AreRowDetailsFrozen="True">
        <DataGrid.Columns>
            <DataGridTextColumn Binding="{Binding KEY}" Visibility="Hidden" IsReadOnly="True"></DataGridTextColumn>
            <DataGridTextColumn Binding="{Binding CHARACTERISTIC_CODE}" Header="Unit" IsReadOnly="True" />
            <DataGridTextColumn Binding="{Binding UNIT_CHAR}" Header="Unit" IsReadOnly="True" />
            <DataGridTextColumn Binding="{Binding IC_DEF_CHAR_NUMERIC}" Header="Number" IsReadOnly="False"/>
            <DataGridTextColumn Binding="{Binding IC_DEF_CHAR_TEXT}"  Header="Text" IsReadOnly="False" />
            <DataGridTextColumn Binding="{Binding IsNumeric}"  Header="Status" IsReadOnly="True" />
            <DataGridTextColumn Binding="{Binding IsText}" Header="Status" IsReadOnly="True" />
        </DataGrid.Columns>

我使用dataGrid1.ItemsSource = dTable.DefaultView将其绑定到代码中的数据表,并使用SqlDataAdapter更新方法dAdapter.Update(dTable)保存更改的按钮

问题是我想在记录为NoNumeric时禁用编辑IC_DEF_CHAR_TEXT字段,而在记录IsText时禁用IC_DEF_CHAR_TEXT.我尝试绑定到IsReadOnly属性但发现它不可绑定,因此我为这两个字段创建了模板,并将IsEnabled属性绑定到IsText和IsNumeric字段.

<DataGrid AutoGenerateColumns="False" HorizontalAlignment="Left" Margin="27,42,0,0" Name="dataGrid1" VerticalAlignment="Top"  AreRowDetailsFrozen="True">
        <DataGrid.Columns>
            <DataGridTextColumn Binding="{Binding KEY}" Visibility="Hidden" IsReadOnly="True"></DataGridTextColumn>
            <DataGridTextColumn Binding="{Binding CHARACTERISTIC_CODE}" Header="Unit" IsReadOnly="True" />
            <DataGridTextColumn Binding="{Binding UNIT_CHAR}" Header="Unit" IsReadOnly="True" />
            <DataGridTemplateColumn …
