问题描述

我在windows中工作c＃vs 2015



我有两个用于国家阿拉伯语和郡英语的组合框

我的用户永久忘记并为组合框2选择错误的国家



我的代码如下：

I work in windows form c# vs 2015

I have two combo box for country Arabic and county English

I need if user select value from combo box 1 select same value from combo box 2

my user permanent forget and select wrong country for combo box 2

my code as below :

var dataSourceAr = new List<Country>();
            dataSourceAr.Add(new Country() { Name = "اختر دوله", Value = 0 });
            dataSourceAr.Add(new Country() { Name = "الاردن", Value = 1 });
            dataSourceAr.Add(new Country() { Name = "الإمارات", Value = 2 });
            dataSourceAr.Add(new Country() { Name = "السعوديه", Value = 3 });
            dataSourceAr.Add(new Country() { Name = "البحرين", Value = 4 });
            dataSourceAr.Add(new Country() { Name = "تونس", Value = 5 });
           
            this.comboBox2.DataSource = dataSourceAr;
            this.comboBox2.DisplayMember = "Name";
            this.comboBox2.ValueMember = "Value";

 var dataSourceEn = new List<Country>();
            dataSourceEn.Add(new Country() { Name = "SelectCountry", Value = 0 });
            dataSourceEn.Add(new Country() { Name = "Jordon", Value = 1 });
            dataSourceEn.Add(new Country() { Name = "Emarate", Value = 2 });
            dataSourceEn.Add(new Country() { Name = "Saudia", Value = 3 });
            dataSourceEn.Add(new Country() { Name = "Bahreen", Value = 4 });
            dataSourceEn.Add(new Country() { Name = "Tunisi", Value = 5 });
           


            comboBox1.DataSource = dataSourceEn;
            comboBox1.DisplayMember = "Name";
            comboBox1.ValueMember = "Value";
public class Country
    {
        public string Name { get; set; }
        public int Value { get; set; }
    }

如果用户从组合框1中选择值1，我需要从组合框2中自动选择值1



i需要强迫他在两个组合框中获得相同的值



如果他从com框中选择值3，从梳子中选择值3方框3



如果可能的话怎么做？



我尝试过：

so that i need if user select value 1 from combo box 1 automatic select value 1 from combo box 2

i need to force him to get same value in two combo box

IF HE select value 3 from com box 1 select value 3 from comb box 3

How to do that if possible ?

推荐答案

将 SelectedIndexChanged 事件添加到 dataSourceAr 组合框

Add SelectedIndexChanged event to the dataSourceAr combobox

private void dataSourceAr_SelectedIndexChanged(object sender, EventArgs e)
      {
          this.dataSourceEn.SelectedIndex = (sender as ComboBox).SelectedIndex;
      }
