DataGridView linked to DataTable with Combobox column based on enum

Question

Having spent a lot of yesterday searching on this one I have to give up.

I have a DataGridView linked to a Datatable. One of the columns is an enum and I want that t

Answer 1

i had this problem myself, here is how i fixed it:

 DataGridViewComboBoxColumn col = new DataGridViewComboBoxColumn();
 col.ValueType = typeof(MyEnum);
 col.ValueMember = "Value";
 col.DisplayMember = "Display";
 colElementtyp.DataSource = new MyEnum[] { MyEnum.Firstenumvalue, MyEnum.Secondenumvalue }
     .Select(value => new { Display = value.ToString(), Value = value })
     .ToList();

the DataGridViewComboBoxCell has to be bound to the enum or integer. I guess the column of your datatable is integer, then it should work.

EDIT:

this should work dynamic:

 System.Array enumarray = Enum.GetValues(typeof(MyEnum)); 
 List lst = enumarray.OfType().ToList();
 DataGridViewComboBoxColumn col = new DataGridViewComboBoxColumn();
     col.ValueType = typeof(MyEnum);
     col.ValueMember = "Value";
     col.DisplayMember = "Display";
     colElementtyp.DataSource = lst 
         .Select(value => new { Display = value.ToString(), Value = value })
         .ToList();

shorter:

 DataGridViewComboBoxColumn col = new DataGridViewComboBoxColumn();
 col.ValueType = typeof(MyEnum);
 col.ValueMember = "Value";
 col.DisplayMember = "Display";
 colElementtyp.DataSource = Enum.GetValues(typeof(MyEnum)).OfType().ToList() 
         .Select(value => new { Display = value.ToString(), Value = value })
         .ToList();
