將 Datatable 與 DataGridView 綁在一起

//方式一
DataTable dt = new DataTable("table");
DataColumn colItem = new DataColumn("item", Type.GetType("System.String"));
dt.Columns.Add(colItem);
// Add five items.
DataRow NewRow;
for (int i = 0; i < 5; i++)
{
NewRow = dt.NewRow();
NewRow["item"] = "Item " + i;
dt.Rows.Add(NewRow);
}
// Change the values in the table.
dt.Rows[0]["item"] = "cat";
dt.Rows[1]["item"] = "dog";
dt.AcceptChanges();
//方式二
//DataTable dt = new DataTable();
//dt.Columns.Add(new DataColumn("Item", typeof(string)));
//dt.Columns.Add(new DataColumn("Color", typeof(string)));
//dt.Rows.Add(new string[] { "cat", "brown" });
//dt.Rows.Add(new string[] { "dog", "white" });
//原本的 dataGridView
dataGridView1.DataSource = dt;
//過濾後的 dataGridView
DataView view = new DataView(dt);
view.RowFilter = "Item='" + "dog" + "'";
DataTable table = view.ToTable();
dataGridView2.DataSource = table;
