GridView

A GridView is bound by assigning its DataStore property to a collection. The control supports MVVM in such that if the collection implements INotifyCollectionChanged, such as the ObservableCollection<T>, it will update as changes are made to the underlying collection.

There are a number of available Cell types:

• CheckBoxCell
• ComboBoxCell
• ImageTextCell
• ImageViewCell
• TextBoxCell

When creating cells, you must set its binding which can be done via index, property via reflection, or delegate/lambda methods.

POCO

The best way to use the GridView is to use a POCO or DTO. Cells can reference properties of your objects to populate its data.

As an example:

using Eto.Forms;
using Eto;
using System.Collections.ObjectModel;

class MyPoco
{
	public string Text { get; set; }

	public bool Check { get; set; }
}

class MyForm : Form
{
	public MyForm()
	{
		var collection = new ObservableCollection<MyPoco>();
		collection.Add(new MyPoco { Text = "Row 1", Check = true });
		collection.Add(new MyPoco { Text = "Row 2", Check = false });

		var grid = new GridView { DataStore = collection };

		grid.Columns.Add(new GridColumn {
			DataCell = new TextBoxCell { Binding = Binding.Property<MyPoco, string>(r => r.Text) },
			HeaderText = "Text"
		});

		grid.Columns.Add(new GridColumn {
			DataCell = new CheckBoxCell { Binding = Binding.Property<MyPoco, bool?>(r => r.Check) },
			HeaderText = "Check"
		});
		Content = grid;
	}
}

DataTable

To bind to a DataTable (as commonly provided by SQL sources), you can use the following strategy by converting each row to an anonymous type (or POCO).

using System.Linq;
using Eto.Forms;


class MyForm : Form
{
	public MyForm()
	{
		var table = new DataTable();
		table.Columns.Add("TextColumn");
		table.Columns.Add("CheckColumn", typeof(bool));

		table.Rows.Add("Row 1", true);
		table.Rows.Add("Row 2", false);

		var collection = table.Rows.Cast<DataRow>()
			.Select(x => new { Text = x[0], Check = x[1] })
			.ToList();

		var grid = new GridView { DataStore = collection };

		grid.Columns.Add(new GridColumn
		{ 
			DataCell = new TextBoxCell("Text"),
			HeaderText = "Text"
		});
		grid.Columns.Add(new GridColumn
		{ 
			DataCell = new CheckBoxCell("Check"),
			HeaderText = "Check"
		});

		Content = grid;
	}
}
