I failed to bind the combobox selectedvalue.
 public void InitializePage()
 {          
    cbStatus.DataSource = Enum.GetValues(typeof(CourseStudentStatus));
 }
on my constructor
 public EditCourseForm(int status)
 {
     InitializePage();                      
开发者_如何学编程     cbStatus.SelectedText = Enum.GetName(
        typeof(CourseStudentStatus), status).ToString();         
 }
I have tried this too. 
cbStatus.SelectedValue = Status
but I'm not able to set SelectedValue on the ComboBox.
Update My enum
 public enum CourseStudentStatus
{
    Active = 1,
    Completed = 2,
    TempStopped = 3,
    Stopped = 4,
}
Problem is  resolved.
cbStatus.SelectedItem = (CourseStudentStatus)status; 
Hope it helps.
Have you tried
public EditCourseForm(CourseStudentStatus status)
{
    InitializePage();            
    cbStatus.SelectedItem= status;
}
Change your InitializePage() function code to this
public void InitializePage() {
    cbStatus.DataTextField = Enum.GetName(typeof(CourseStudentStatus));
    cbStatus.DataValueField = Enum.GetValues(typeof(CourseStudentStatus));
}
Updated Try with this.
var itemValues = Enum.GetValues(typeof(CourseStudentStatus)).Cast<CourseStudentStatus>().ToDictionary(obj => obj.ToString(), obj => obj.GetHashCode()).ToList();
        comboBox1.DisplayMember = "Key";
        comboBox1.ValueMember = "Value";
        comboBox1.DataSource = itemValues;
here itemValues is a type of List<KeyValuePair<string, int>>
