解决方案

A DataGridViewComboBoxColumn 没有的SelectedIndex 和的SelectedValue 属性。然而，你可以通过设置在 值 属性。的SelectedValue 的相同的行为p>

上。例如第一个索引值的成员具有值2，那么你应该设置 .value的=2来设置第一个指标选择。

例如

  myDataGridViewComboBoxColumn.Value = 20; 
  

在你的情况

  myDataGridViewComboBoxColumn.Value = CourseStudentStatus.EnumToBeSelected.ToString（）; 
  

下面是关于的 DataGridViewComboBoxColumn

Are you sure i need such a long code to just have the first item selected??????

解决方案

A DataGridViewComboBoxColumn has no SelectedIndex, and SelectedValue properties. However you can get the same behavior of SelectedValue by setting the Value property.

For instance on first index the value member has value 2 then you should set .Value = "2" to set the first index selected.

For example

myDataGridViewComboBoxColumn.Value = "20";

In your case

myDataGridViewComboBoxColumn.Value = CourseStudentStatus.EnumToBeSelected.ToString();
