代碼隱藏:
public partial class Student_ListCourses : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
try
{
if (!IsPostBack)
{
System.Data.DataTable dt;
BusinessLayer.CoursesController oCourse = new BusinessLayer.CoursesController();
dt = oCourse.Select();
DropDownListCourses.DataSource = dt;
DropDownListCourses.DataValueField = "CourseID";
DropDownListCourses.DataTextField = "CourseName";
DropDownListCourses.DataBind();
}
}
}
protected void ButtonView_Click(object sender, EventArgs e)
{
try
{
System.Data.DataTable dt;
BusinessLayer.SubjectsController oCourse = new BusinessLayer.SubjectsController();
oCourse.CourseID = int.Parse(DropDownListCourses.SelectedValue);
dt = oCourse.Select();
RepeaterDataVeiw.DataSource = dt;
RepeaterDataVeiw.DataBind();
}
catch (Exception ex)
{ }
}
}
您需要向我們展示您的代碼。 –
看來你的代碼在中間缺少一個部分。之後 asp:Content> – paqogomez
