方式一、通过泛型Dictionary绑定
View Code Dictionary< int, string> mydic = new Dictionary< int, string>() { { 0, " aaaa "}, { 1, " bbbb "}, { 2, " cccc "} }; cobxUserType.ItemsSource = mydic; cobxUserType.SelectedValuePath = " Key "; cobxUserType.DisplayMemberPath = " Value ";
然后通过cobxUserType.SelectedValue获得选中的值即可
方法二、通过数据集绑定
View Code WebDictClassServices.WebDictClass webDict = new WebDictClass(); private void Window_Loaded( object sender, RoutedEventArgs e) { BindCombox(); BindCombox2(comboBox2, 0, " 选择系列 "); BindCombox2(comboBox3, 0, " 选择型号 "); } // 绑定下拉控件1 private void BindCombox() { DataTable dt = webDict.GetMainBrand(); if (dt != null && dt.Rows.Count == 0) { dt = new DataTable(); DataColumn dc1 = new DataColumn( " Title "); DataColumn dc2 = new DataColumn( " ID "); dt.Columns.Add(dc1); dt.Columns.Add(dc2); DataRow row = dt.NewRow(); row[ " title "] = " 按品牌选择 "; row[ " ID "] = " 0 "; dt.Rows.Add(row); } else { DataRow row = dt.NewRow(); row[ " title "] = " 按品牌选择 "; row[ " ID "] = " 0 "; dt.Rows.Add(row); } DataView dv=dt.DefaultView; dv.Sort= " ID asc "; combMainBrand.ItemsSource =dv; this.combMainBrand.DisplayMemberPath = " Title "; this.combMainBrand.SelectedValuePath = " ID "; combMainBrand.SelectedValue = " 0 "; } // 绑定下拉控件 private void BindCombox2(ComboBox comb, int id, string message) { DataTable dt = null; if (id == 0) { dt = new DataTable(); DataColumn dc1 = new DataColumn( " Title "); DataColumn dc2 = new DataColumn( " ID "); dt.Columns.Add(dc1); dt.Columns.Add(dc2); DataRow row = dt.NewRow(); row[ " Title "] = message; row[ " ID "] = " 0 "; dt.Rows.Add(row); } else { dt = webDict.GetCarSeriesByBrand(id); DataRow row = dt.NewRow(); row[ " Title "] = message; row[ " ID "] = " 0 "; dt.Rows.Add(row); } DataView dv = dt.DefaultView; dv.Sort = " ID asc "; comb.ItemsSource = dv; comb.DisplayMemberPath = " Title "; comb.SelectedValuePath = " ID "; if (dt.Rows.Count!= 0) { comb.SelectedValue = dt.Rows[ 0][ " ID "]; } } private void combMainBrand_SelectionChanged( object sender, SelectionChangedEventArgs e) { int id = Convert.ToInt32(combMainBrand.SelectedValue); BindCombox2(comboBox2, id, " 选择系列 "); BindCombox2(comboBox3, Convert.ToInt32(comboBox2.SelectedValue), " 选择型号 "); } private void comboBox2_SelectionChanged( object sender, SelectionChangedEventArgs e) { int id = Convert.ToInt32(comboBox2.SelectedValue); BindCombox2(comboBox3, id, " 选择型号 "); }
三、IList绑定(类似winForm)
View Code public class Info { public int Id { get; set; } public string Name { get; set; } }
// 绑定用户类型 private void bindUserType() { IList<Info> list = new List<Info>() { new Info(){ Id= 0, Name= " 供应商 "}, new Info(){ Id= 1, Name= " bbbbbb "} }; cobxUserType.ItemsSource = list; cobxUserType.SelectedValuePath = " Id "; cobxUserType.DisplayMemberPath = " Name "; }
