问题描述

我使用下拉列表.我给datatextfield = name
和datavaluefield = id
现在我想检索在下拉列表中选择的特定名称的ID.
请告诉我怎么做


在此先感谢

i m using the dropdownlist. I m giving the datatextfield= name
and datavaluefield=id
now i want to retreive the id of the particular name which is selected in dropdownlist.
Please tell me how to do it


thanks in advance

推荐答案

TextBox1.Text = datatextfield.SelectedValue.ToString()

TextBox1.Text=datatextfield.SelectedValue.ToString()

String ans =";
ans = dropdownlist1.SelectedItem.Value;

String ans="";
ans=dropdownlist1.SelectedItem.Value;

最佳方法是:

var res = dropDownList.SelectedItem;

您得到了完整的结果，然后开始处理必需的项目

The Best approach will be:

var res = dropDownList.SelectedItem;

You get whole result, then start processing required items
