问题描述

我有要求，请帮助我。

我们有员工报名表，因为我们有课程下拉列表，其中包含课程列表。每位员工在保存员工信息的同时应选择课程。我们在Employee表中插入了选定的课程ID。

现在我们得到了一个更改，因为所有现有课程都应该被取消激活并在编辑员工表单中创建新课程我们应该显示暂停（之前选择）课程暂时但在下拉列表中我们应该显示当前活动课程列表以选择新引入的课程。

请帮助我。我面临的问题是显示停用的课程作为下拉列表临时默认项目。

注意：停用的课程不应显示在包含活动列表项的下拉列表中。

问候，

Ramesh

I have a requirement, please help me.

We have employee entry form, in that we have course dropdown list it contains list of courses. Each employee should select course while saving employee information. We are inserting Selected course id in Employee table.

Now we got a change as all existing courses should be deactiveted and create new courses similarly in Edit employee form we should display deactivated (previously selected) course as temporarily but on dropdown list we should display present active course list to select newly introduced course.

Please help me. I am facing problem to display deactivated course as dropdownlist temporary default item.

Note : deactivated course should not display in dropdown list with active list items.

推荐答案

foreach (ListItem item in drpCourses.Items)
{
  if (int.Parse(item.Value.ToString()) <11) //let's say last old id is 10
  {
     item.Attributes.Add("Style", "color:silver");
     item.Attributes.Add("Disabled", "true");
  }
}
