BindingSource.ResetItem Method

The ResetItem method notifies all controls bound to the item at the specified Position to refresh their values. The method does this by raising the ListChanged event with ListChangedEventArgs.ListChangedType set to ListChangedType.ItemChanged.

ResetItem is automatically called whenever changes are made to the value of an individual item. However, the programmer can also call this method explicitly.

The following code example uses a BindingSource component to bind a list to a DataGridView control. The list does not raise change notifications, so the ResetItem method on the BindingSource is used to raise the ListChanged event. This code example is part of a larger example provided in How to: Raise Change Notifications Using the BindingSource ResetItem Method.

// This event handler changes the value of the CompanyName 
// property for the first item in the list. 
void changeItemBtn_Click(object sender, EventArgs e)
{
    // Get a reference to the list from the BindingSource.
    List<DemoCustomer> customerList = 
        this.customersBindingSource.DataSource as List<DemoCustomer>;

    // Change the value of the CompanyName property for the  
    // first item in the list.
    customerList[0].CompanyName = "Tailspin Toys";

    // Call ResetItem to alert the BindingSource that the  
    // list has changed. 
    this.customersBindingSource.ResetItem(0);
}
