Dev LookUpEdit下拉框控件
今天做dev的项目的时候,用到了下拉框控件LookUpEdit控件,但是其中有些表示自己忘了。记录一下,不至于以后不用忘了查询费时间。
//使用LookUpEdit的值
变量=this.lookupedit.editvalue.tostring() //是lookupedit.properties.valuemember的值
变量=this.lookupedit.text.trim() //是lookupedit.properties.displaymember 的值
lookupedit.itemindex=0; //选择第一项,0是索引
comb_xq.Properties.NullText = "全部"; //为null时的text值
lookupedit绑定:可以手动绑定也可以根据查询到的list来绑定;
public class ComboxCommon { public long ID { get; set; } public string Name { get; set; } } /// <summary> /// 卡类型下拉框 /// </summary> private void bindcombPrice() { IList<ComboxCommon> infoList = new List<ComboxCommon>(); ComboxCommon info1 = new ComboxCommon(); info1.Name = "类型1"; info1.ID = 0; infoList.Add(info1); ComboxCommon info2 = new ComboxCommon(); info2.Name = "类型2"; info2.ID = 1; infoList.Add(info2); lookupedit.Properties.DataSource = infoList; lookupedit.Properties.ValueMember = "ID"; lookupedit.Properties.DisplayMember = "Name"; comb_Price.ItemIndex = 0; }
//list数据绑定
for (int i = 0; i < list.Count; i++)
{
ComboxStreetInfo info1 = new ComboxStreetInfo();
info1.Name = list[i].Name;
info1.ID = list[i].ID;
infoList.Add(info1);
}
lookupedit.Properties.DataSource = infoList;
lookupedit.Properties.ValueMember = "ID";
comb_Street.Properties.DisplayMember = "Name";
