lookupedit获得选定的价值

Question

我正在使用devexpress和visualstudio 2010.我有LookUpEdit控件,我想选择值,但是用指定的格式显示它:有一个我用buttonEdit的例子:

    CurrentEvent.fkVersion = selectedVersion;
    m_cVersionButtonEdit.EditValue= CurrentEvent.fkVersion.FormattedProduct;
    m_cVersionButtonEdit.Refresh(); 

"selectedVersion"是按下按钮后我在对话框中选择的对象.

现在我必须这样做,但使用lookupEdit并从dropDownlist中选择版本.那么问题是如何获得选定值？

Answer 1

我不确定你在问什么,但获取选定值的最简单方法是这样的:

public partial class Form1 : Form
{
    public class Example
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Description { get; set; }
    }

    public List<Example> elist = new List<Example>();

    public Form1()
    {
        InitializeComponent();
        for (int i = 0; i < 10; i++)
        {
            elist.Add(new Example() { Id = i, Name = "Name" + i, Description = "Description " + i });
        }
        lookUpEdit1.Properties.DataSource = elist;
        lookUpEdit1.Properties.DisplayMember = "Name";
    }

    private void lookUpEdit1_EditValueChanged(object sender, EventArgs e)
    {
        var item = lookUpEdit1.GetSelectedDataRow() as Example;
    }
}
