[piaoyao888]

请问一下ComBox如何绑定数据源，将value属性和Text属性一块绑定！

[piaoyao888]

给combobox设置datasource,displaymember,valuemember

[marvelstack]

mboBox1.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

[renlei413326889]

请问
this.ComboBox1.DisplayMember = "Name";//字段名
this.ComboBox1.ValueMember = "userId";//字段名
---两个字段名怎么不相同？
分别表示什么？
有实例么？谢谢！
