如何更改选择c＃动态使用c＃（not xaml）中的Binding（）更改combobox值 [英] How to update combobox value on changing selection c# dynamically using Binding() in c# (not xaml)

问题描述

我是c＃silverlight5初学者，我有一个情况，我必须使用c＃动态创建一个组合框，并保留项目。但是现在当我运行它运行正确显示最后一个值默认情况下，但是当我选择另一个值，它不更新在附近的文本框中的值，因为它不工作动态。

I am c# silverlight5 beginner and i have a situation that i have to created a combo box dynamically using c# and kept items in it. But the problem now when i run it run properly showing the last value by default but when i select the another value it don't update the that value in the text box near by because it is not working dynamically.

我想我需要添加一些选择改变或一些其他事件使用c＃。但我不知道如何做到这一点。请注意，我使用c＃只创建了这个组合框。

I guess i need to add some selection changed or some other event using c#. But i dont know how to do that. Please note that i have created this combo box using c# only.

如何将对应的值更改为combobox值？ / strong>

推荐答案

最后，我使用 SelectionChanged 创建 SelectionChangedEventHandler 。
代码如下（可能对一些未来用户有用）：

At last i have done it using SelectionChanged and creating SelectionChangedEventHandler. The code is as below (may be useful for some future user):

cb.SelectionChanged + = new SelectionChangedEventHandler（comboBox1_SelectionChanged） ; in convert（）函数和外部转换器函数：

cb.SelectionChanged += new SelectionChangedEventHandler(comboBox1_SelectionChanged); in converter() function and outside converter function :

 void comboBox1_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        txtblk2.Text = cb.SelectedValue.ToString() + " millions";
    }
