在winform中
this.comboBox1.DataSource = ds1.Tables[0];
this.comboBox1.DisplayMember = "Name";
this.comboBox1.ValueMember = "Num";
数据是用以上方法绑定的,
我现在是想遍历得到每项对应的num,不是Name,现在不用dataTable,能否遍历得到每一项对应的关联数据num
对选中项来说,得到其value的方法是comboBox.SelcetedValue,得到每一项如何操作

{
values = cmbScaleMode.items[i].Tostring;
}整到了text..弄过来的来吧。。
这个你要自己写一个对象来存储Text和Value,因为comboxBOx1.Items里面是object对象public class ComboBoxItem
{
private string _value;
private string _text; public string Value { get { return _value; } }
public string Text { get { return _text ; } } public ComboBoxItem (string cValue, cText)
{
this._value = cValue;
this._text = cText;
}
}
ComboBox myBox = new ComboBox ();
myBox.Items.Add (new ComboBoxItem ("1", "January"));
myBox.Items.Add (new ComboBoxItem ("2", "February"));for(int i=0;i<this.comboxBOx1.Items.Count;i++)
{
ComboBoxItem item=comboxBOx1.Items[i] as ComboBoxItem;
string getValue=item.Value;
}
dt.Columns.Add("id");
dt.Columns.Add("name");
DataRow dr = dt.NewRow();
dr[0] = "1000";
dr[1] = "测试1000";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr[0] = "1001";
dr[1] = "测试1002";
dt.Rows.Add(dr); comboBox1.DataSource = dt;
comboBox1.DisplayMember = "name";
comboBox1.ValueMember = "id";
comboBox1.Refresh(); foreach (Object oDic1 in comboBox1.Items)
{
DataRowView dr1 = (DataRowView)oDic1;
MessageBox.Show(dr1["id"].ToString() + "_______" + dr1["name"].ToString());
}
