WPF Datagrid : Find Columns currently visible on screen

Question

I want to allow the user to add a column and for that column to appear on screen. Is there a way to find which columns are currently on screen?

Answer 1

The property Columns of the Datagrid is an ObservableCollection<DataGridColumn>. You will find everithing you need there. If you want to know if any given column is visible, simply check MyDatagrid.Columns[i].Visibility

Adding columns in code is simple:

DataGridTemplateColumn col = new DataGridTemplateColumn();
MyDatagrid.Columns.Add(col);
