WPF Datagrid UserControl with definable columns

Question

I have an object something like this:

public class Item 
{
  public string Name;
  public int Id;
  public int Quantity;
  public decimal Volume;
  public decimal Cost;
}

I'm wanting to create a reusable user control which would take a list of these objects and display them in a datagrid. The trick is that I want to specify which of the properties are shown in the datagrid for each instance of the control. Unfortunately my WPF skills are not up to the tasks and I don't want to create a specific control for each combination that I will want to use, as that feels like a lot of work for very similar code items. Any help to pointers of how to accomplish this would be greatly appreciated.

You can use the Columns property of your datagrid to interact with the columns and hide the columns you don't want.

datagrid.Columns.RemoveAt(IndexOftheColumn);

or if you named your columns

datagrid.Columns.RemoveAll(x => x.Name = "column name");

or if it is possible that you will need to column later

datagrid.Columns[IndexOftheColumn].Visibility = Visibility.Collapsed;

It is also possible to do this with pure Xaml with bindings but since you are new to Wpf I would suggest doing it in the code behind (the .cs of your Wpf control) first.

As for selecting which columns to hide you can pass a list of names for the columns you want to remove in the constructor of the control or with a binding. There are a lot of ways to do it.

Or you could do the opposite and add columns dynamically based on your needs.
