单选按钮检查属性数据绑定 [英] Radio button checked property data binding

问题描述

在我的表格上，有关团体的信息显示为：



1.团体名称：__________（i / p control：textBox）

2.主要是：O否O是（i / p控制：radioButtons）



我想数据绑定上面两个单选按钮的checked属性，与我的对象。

对象如下：

On my form information about a group is displayed as:

1. Group Name:__________ (i/p control: textBox)
2. Is Primary: O No O Yes (i/p control: radioButtons)

I want to data bind the checked property of the two radio buttons above, with my object.
The object is as:

public class DTOItemGroup
    {
        public short id { get; set; }
        public string name { get; set; }
        public Nullable<short> idParent { get; set; }
    }

回到代码中，我尝试将其绑定为：

Back in the code, I tried binding it as:

BindingSource bs;
void InitializeThis(StockTools stockTools)
        {
            bs = new BindingSource();
            bs.DataSource = typeof(DTOItemGroup);
            form_StockTools.tb_GroupName.DataBindings.Add("Text", bs, "name");
            form_StockTools.rb_IsPrimaryNo.DataBindings.Add("Checked", bs, "idParent", true, DataSourceUpdateMode.OnPropertyChanged, false);
            form_StockTools.rb_IsPrimaryYes.DataBindings.Add("Checked", bs, "idParent", true, DataSourceUpdateMode.OnPropertyChanged, true);
        }

绑定文本框工作正常。但是，对于单选按钮，绑定根本不起作用。每当我更改附加到绑定源（bs）的对象时，都不会检查单选按钮。



我对绑定很新。请指导我如何数据绑定一组单选按钮。



我尝试过：



我谷歌搜索单选按钮检查属性数据绑定教程谷歌，但没有任何帮助。我知道这一定是一件容易的事，但我无法弄明白。

Binding for the textbox is working fine. But, for radio buttons, binding is not working at all. Whenever I change the object attached to binding source (bs), the radio buttons doesn't get checked.

I am very new to binding. Please guide me on how to data bind a group of radio buttons.

What I have tried:

I googled for radio button checked property data binding tutorial over google but had no help. I know this must be an easy task, but I can't really figure out it.
