相互排斥的RadioButtons按行排列，而不是GridView中的列 [英] Mutually exclusive RadioButtons by row and not by column in GridView

问题描述

具有5列的GridView：
- 文本
- 单选按钮
- 单选按钮
- 单选按钮
- 复选框

文本列是通过绑定到List<>自动填充的。
关于我需要的单选按钮，它们是按行而不是按列相互排斥的;它们的值由用户交互设置。

如果我像下面的例子那样设置GroupName属性，所有的单选按钮都是按行和按列互斥的。 p>

您能否提供建议？

解决方案

如果您可以修改 ListView 绑定到的列表中的对象，那么您可以在该对象中添加一个唯一标识该特定对象的属性，只需以此目的。例如：

  public class DataObject 
 {
 public void DataObject（）
 {
 Id = Guid.NewGuid（）; 
} 
 
 public Guid Id {get;私人设置; } 
} 
  

然后你可以绑定你的 GroupName b
$ b

 < RadioButton Name =radioToInsertGroupName ={Binding Id，Mode = OneWay }/> 
  

由于每行代表列表中的不同对象，因此 Id 仅在1行的范围内共享。

GridView with 5 columns: - text - radiobutton - radiobutton - radiobutton - checkbox

The text column is automatically populated through a binding to a List<>. About the radiobuttons I need they are mutually exclusive by row and not by column; their value is set by user interaction.

If I set the GroupName property like in the following exemple, all the radiobuttons are mutually exclusives both by row and by column.

Could you please advise? Thanks in advance!

解决方案

If you can modify the object in the list that the ListView is binding to, then you can add a property in that object which uniquely identifies that particular object, just for this purpose. For example:

public class DataObject
{
    public void DataObject()
    {
        Id = Guid.NewGuid();
    }

    public Guid Id{ get; private set; }
}

Then you can bind your GroupName to this property:

<RadioButton Name="radioToInsert" GroupName="{Binding Id, Mode=OneWay}" />

Because each row represents a different object in your list, so this Id is only shared in the scope of 1 row.
