很简单，你需要将所有值附加到sql查询中的单个列中将该列绑定到dropdownlist的value字段。然后在split功能的帮助下，您可以获得所有的值...



示例 -

选择名称+' - '+ branch +' - '+ rollno作为yourtablename的值

这里你可以将值列绑定到下拉列表值字段。

on the C＃页面使用如下代码

  var   value  = ddl.SelectedValue.Split（'   - '）。ToList（）; 
字符串 name = lowerUpperval [ 0 ]; 
字符串 branch = lowerUpperval [ 1 ]; 
字符串 rollno = lowerUpperval [ 2 ]; 

享受

Happy Codding !!!

首先从数据库中获取数据表...



然后，如果你的数据库包含两列，一个名为Text，另一个名为Value

你只需说



yourDropDownList.DataSource = yourDataTable;

yourDropDownList.DataTextField =Text;

yourDropDownList.DataValueField =Value;

yourDropDownList .DataBind（）;

how to bind multiple value in dropdownlist from the database

It,s very simple you need to append all that values to a single column in sql query and bind that column to value field of dropdownlist.Then by the help of split fuction you can get all the value...

Example-
select name + '-' + branch + '-' + rollno as value from yourtablename
here you can bind the value column to the dropdownlist value field.
on the C# page use code as as below

var value= ddl.SelectedValue.Split('-').ToList();
             String  name=lowerUpperval[0];
             String  branch= lowerUpperval[1];
             String  rollno=lowerUpperval[2];

Enjoy
Happy Codding!!!

First get a datatable from the database...

Then if your database contains two columns, one named "Text" and one named "Value"
you just say

yourDropDownList.DataSource = yourDataTable;
yourDropDownList.DataTextField = "Text";
yourDropDownList.DataValueField = "Value";
yourDropDownList.DataBind();
