Hide columns in a DataGridView with a list <> as a DataSource?

Question

I have List<>a class X.

XIt has 3 columns: a, band c.

Now I bind the list to DataGridView:

dataGrid.DataSource = list;

How to show the columns of a and cin GridView, so hide the column b?

I will not edit the list itself, if possible, and will not generate a new list, if possible.

Any solution here?

Answer 1

I assume your class is as follows:

private class MyClass {
  [DisplayName("Foo/Bar")]
  public string FooBar { get; private set; }
  [Browsable(False)]
  public decimal Baz { get; private set; }
  [DisplayName("Baz")]
  public CurrencyBaz
  {
        get { return string.Format(Baz, "C2"); }
  }
}

In the above code, gridview column names look like this

• column name1: ("Foo/Bar")
• column name2: "Baz"
• 3: "CurrencyBaz"

, ... [ (False)]
