关于combobox绑定的问题
我想对三个combobox绑定同一张表，但相互之间不会同时改变
但是下面这段代码的结果是两个combobox一起变，不是相互独立的，一改就一起变..... 到底要怎么写啊？

PDMSDataSet pDMSDataSet = new PDMSDataSet();
PDMSDataSetTableAdapters.HospitalTableAdapter adapter = new PDMS.PDMSDataSetTableAdapters.HospitalTableAdapter();
adapter.Fill(this.pDMSDataSet.Hospital);
BindingSource bindinSource = new BindingSource();
bindinSource.DataSource = this.pDMSDataSet;
bindinSource.DataMember = "Hospital";
Fircombo.DataSource = bindinSource;
Fircombo.DisplayMember = "Hname";
Fircombo.ValueMember = "Hid";

Seccombo.DataSource = bindinSource;
Seccombo.DisplayMember = "Hname";
Seccombo.ValueMember = "Hid";

[解决办法]
三个 Combobox 指定不同的 BindingSource

C# code

PDMSDataSet pDMSDataSet = new PDMSDataSet();PDMSDataSetTableAdapters.HospitalTableAdapter adapter = new PDMS.PDMSDataSetTableAdapters.HospitalTableAdapter();adapter.Fill(this.pDMSDataSet.Hospital);Fircombo.DataSource = new BindingSource(pDMSDataSet, "Hname");Fircombo.DisplayMember = "Hname";Fircombo.ValueMember = "Hid";Seccombo.DataSource = new BindingSource(pDMSDataSet, "Hname");Seccombo.DisplayMember = "Hname";Seccombo.ValueMember = "Hid";
[解决办法]
拷贝3份dataset。每份绑定一个combobox
