System.Windows.Forms.DataGridView does not display data
- by Water Cooler v2
All I am doing is a simple:
// Both the methods, order.GetAllOrderItems() and order.GetOrderedItemsWhereBrandIs("foo")
// return an IEnumerable<T> so the assignment to the DataSource property of the DataGridView
// should be fine. The problem is in re-assigning the data source property.
public void DisplayItems()
{
// The data appears if I have just this line.
dgvOrderedItems.DataSource = order.GetAllOrderItems();
dgvOrderedItems.DataSource = null;
// This time the data grid does not take the new data source. Instead, because
// of the null assignment in the previous statement, it displays no data at all.
dgvOrderedItems.DataSource = order.GetOrderedItemsWhereBrandIs("Lenovo");
}
My question is: is there a way to change the data source of a DataGridView control once it has been set? I am using C# 4.0 and Visual Studio 2010 for development.
