推荐答案

尝试使用此代码来获取特定的索引值

Hi,

try this code to get particular index value

sd.Items [3].Value

将数据绑定到下拉列表后，所有Best

All the Best

写这行

after binding the data to dropdownlist

write this line

dropdownlist1.SelectedIndex="3";

示例:

DataTable sample = new DataTable();
ddlSample.datatextfield = "name" ;
ddlSample.datavaluefield = "id";
ddlSample.datasource = sample;
ddlSample.databind();

string id = ddlsample.selecteditem.value

;
