结合两个组合框相同的数据源，每个组合都会有个人行为 [英] Binding two combo boxes to the same data source,that each combo will have individual behaviour

问题描述

现在，当我第一次在组合框中选择项的第二个模仿的选择。
我希望能够在每个组合框分别选择。
谢谢你。

 列表＆LT; W6AdminUIs2.DictionaryObject＆GT; taskStatuses = W6AdminUIs2.GlobalFunctions.GetDictionaryItems（TaskStatus）;    //初始化的状态的绑定源。
    BindingSource的bsFromStatuses =新的BindingSource（）;
    bsFromStatuses.DataSource = taskStatuses;    //从组合框绑定到绑定源。
    cBoxFrom.DataSource = bsFromStatuses.DataSource;
    cBoxFrom.DisplayMember =姓名;
    cBoxFrom.ValueMember =键;    //初始化的状态的绑定源。
    BindingSource的bsToStatuses =新的BindingSource（）;
    bsToStatuses.DataSource = taskStatuses;    //从组合框绑定到绑定源。
    cBoxTo.DataSource = bsToStatuses.DataSource;
    cBoxTo.DisplayMember =姓名;
    cBoxTo.ValueMember =键;
 

解决方案

我不知道你用的是什么样的词典，但我正常使用的字典，这code不那样做的：

 词典＆LT;字符串，字符串＆GT;字典=新词典＆LT;字符串，字符串＆GT;（）;
dict.Add（S1，样品1）;
dict.Add（S2，样品2）;
dict.Add（S3，样本3）;
dict.Add（S4，Sample4）;comboBox1.DataSource =新的BindingSource（字典，NULL）;
comboBox1.DisplayMember =值;
comboBox1.ValueMember =钥匙;comboBox2.DataSource =新的BindingSource（字典，NULL）;
comboBox2.DisplayMember =值;
comboBox2.ValueMember =钥匙;
 

Now when i select item in first combo box the second mimic the selection. I want to be able to select in each of the combo boxes individually. Thanks.

 List<W6AdminUIs2.DictionaryObject> taskStatuses = W6AdminUIs2.GlobalFunctions.GetDictionaryItems("TaskStatus");

    // Init the binding source of the statuses.
    BindingSource bsFromStatuses = new BindingSource();
    bsFromStatuses.DataSource = taskStatuses;

    //Bind the "From" combo box to binding source.
    cBoxFrom.DataSource = bsFromStatuses.DataSource;
    cBoxFrom.DisplayMember = "Name";
    cBoxFrom.ValueMember = "Key";

    // Init the binding source of the statuses.
    BindingSource bsToStatuses = new BindingSource();
    bsToStatuses.DataSource = taskStatuses;

    //Bind the "From" combo box to binding source.
    cBoxTo.DataSource = bsToStatuses.DataSource;
    cBoxTo.DisplayMember = "Name";
    cBoxTo.ValueMember = "Key";

解决方案

I don't know what kind of dictionary you are using but i use normal dictionary and this code dont behave like that :

Dictionary<string,string> dict = new Dictionary<string, string>();
dict.Add("S1", "Sample1");
dict.Add("S2", "Sample2");
dict.Add("S3", "Sample3");
dict.Add("S4", "Sample4");

comboBox1.DataSource = new BindingSource(dict, null);
comboBox1.DisplayMember = "value";
comboBox1.ValueMember = "key";

comboBox2.DataSource = new BindingSource(dict, null);
comboBox2.DisplayMember = "value";
comboBox2.ValueMember = "key";
