获取selectedItem客户ID表单列表框 [英] Get selectedItem customerID form Listbox

问题描述

我有一个小问题.

我有2个列表框(ListBox1& ListBox2)
在列表框中，我从数据库中添加了项目(表->教师->名称，ForeName，教师ID).
该表与表-Test(testID，教师ID，testName)有关

将项目添加到ListBox1

Hi, I have a small problem.

I have 2 listboxes (ListBox1 & ListBox2)
In ListBox I have added items from DB (table -> teachers -> Name,ForeName, teachersID).
The table is related to table-Test (testID, teachersID, testName)

add items to ListBox1

///some code here
foreach (var i in teachers)
{
  lLstBox1.Items.Add(string.Format("{0} \t{1}", i.foreName, i.name));
}

一切正常，直到这些代码行.

所以我添加到ListBox1
ListBox1_SelectedIndexChanged

如果在ListBox1中只有Name& ;，则如何获取所选的TeacherID.姓?
我需要获取TeacherID来填充ListBox2项，其中TeachersID是一个变量.

everything works good, until these codelines.

So I added to ListBox1
ListBox1_SelectedIndexChanged

How I can get selected teacherID, if in ListBox1 is only Name & Forename?
I need get teachersID to fill ListBox2 items, where TeachersID is a variable.

private void listBoxSkolotaji_SelectedIndexChanged(object sender, EventArgs e)
{
 //some query.
 foreach(//some code here)
 {
   ListBox2.Items.add(//some code here)
 }

希望您能解决我需要解决的问题！ :)
谢谢

I hope you get the problem, that I need to get solved! :)
Thanks
