C# 下拉框如何绑定

yoshiki317

dropprovince.DataSource = myajax.Getprovince();
        dropprovince.DataTextField = "province_name";
        dropprovince.DataValueField = "province_id";
        dropprovince.DataBind();

堕之旋律

用DropDownList控件
DropDownList.DataSource = DataSet.Tables["YourTaleName"];
        DropDownList.DataTextField = "name";
        DropDownList.DataValueField = "id";
        DropDownList.DataBind();
同ls原理一样

楼 上都 说了!

Combobox算下拉框不,这是WinForm中的..

for example:

SqlConnection con=new SqlConnection("server=.;database=student;uid=sa;pwd=0421");
SqlDataAdapter sda=new SqlDataAdapter("select * from studentDetails",con);
DataSet ds=new DataSet();
sda.Fill(ds,"student");
this.ComboBox1.DataSource=ds.Tables["student"];
this.ComboBox1.DisplayMember="sname";


//如果是WebForm,可以用楼上几位说的DropDownList..

绑定虽然可以提高开发效率,但是伸缩性不好,最好还是自己写,在说绑定你也不知道里面发生了什么

同意楼上

与血有关

this.combobox.datasource=dataset1.tables["tablename"];
this.combobox.displaymember=dataset1.tables["tablename"].columns["name"].tostring();
this.combobox.tag=dataset1.tables["tablename"].columns["flag"];
数据绑定 都类似

ComboBox1.DataSource = myDataSet ;//数据集
ComboBox1.DisplayMember = "person.userId" ;//表名加字段名
ComboBox1.ValueMember = "person.username" ;

this.ComboBox1.DataSource = myDataTable;//数据表
this.ComboBox1.DisplayMember = "Name";//字段名
this.ComboBox1.ValueMember = "userId";//字段名
