我有一个组合框，绑定到Datatable并具有以下属性：

cboCars.ValueMember = "carNo";
How can I select the DisplayMemberwhen I know the ValueMember?
DisplayMember当我知道时如何选择ValueMember？

If you have a ValueMemberset you can select using SelectedValue
如果你ValueMember有一套，你可以选择使用SelectedValue
cboCars.DisplayMember = "carLiscen";
cboCars.ValueMember = "carNo";
cboCars.SelectedValue = "valuemember value";

You can use cboCars.SelectedValue = "123";property for this. Here's a code snippet which will show it in action.
您可以cboCars.SelectedValue = "123";为此使用属性。这是一个代码片段，它将显示它的实际效果。
public void Test()
{
ArrayList info = new ArrayList();
info.Add(new CarInfo { CarLiscen = 123456, CarNo = 123});
info.Add(new CarInfo { CarLiscen = 234567, CarNo = 234 });
cboCars.DataSource = info;
cboCars.DisplayMember = "CarLiscen";
cboCars.ValueMember = "CarNo";
cboCars.SelectedValueChanged +=
delegate(object sender, EventArgs e)
{
if (cboCars.SelectedIndex != -1)
{
this.Text = cboCars.SelectedValue.ToString();
}
};
cboCars.SelectedValue = 234;
}
And if you wonder what is the definition of CarInfo. Here's its code (which is fairly simple):
如果你想知道CarInfo. 这是它的代码（相当简单）：
public class CarInfo
{
public int CarLiscen { get; set; }
public int CarNo { get; set; }
}
Hope this helps.
希望这可以帮助。

You can search for the correct item and set it to that, very simple:
您可以搜索正确的项目并将其设置为该项目，非常简单：
cbTEST.SelectedIndex = cbTEST.FindStringExact("your search string here");
or select an item based on an ListViewItem:
或基于 ListViewItem 选择一个项目：
cbTEST.SelectedIndex = cbTEST.FindStringExact(lvTEST.SelectedItems[0].SubItems[0].Text);
thats it. very simple!
就是这样。很简单！

Hi Guys the best way if searching for a text or value is
嗨，伙计们，如果搜索文本或值，最好的方法是
int Selected;
int count = ComboBox1.Items.Count;
for (int i = 0; (i<= (count - 1)); i++)
{
ComboBox1.SelectedIndex = i;
if ((string)(ComboBox1.SelectedValue) == "SearchValue")
{
Selected = i;
}
}
ComboBox1.SelectedIndex = Selected;
