BindingSource.RemoveAt Method

Note: This method is new in the .NET Framework version 2.0.

Removes the item at the specified index in the list.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public virtual void RemoveAt (
	int index
)
public void RemoveAt (
	int index
)
public function RemoveAt (
	index : int
)

Parameters

index

The zero-based index of the item to remove.

Exception typeCondition

ArgumentOutOfRangeException

index is less than zero or greater than the value of the Count property.

NotSupportedException

The underlying list represented by the List property is read-only or has a fixed size.

These two conditions can be tested with the IsFixedSize and IsReadOnly properties, respectively.

This method raises the ListChanged event.

The following code example demonstrates the List, RemoveAt, and Count members. To run this example, paste the code into a form that contains a BindingSource named BindingSource1, two labels named label1 and label2, and a button named button1. Associate the button1_Click method with the Click event for button1. Visual Basic users will need to add a reference to System.Data.dll.

private void button1_Click(object sender, EventArgs e)
{
    // Create the connection string, data adapter and data table.
    SqlConnection connectionString =
         new SqlConnection("Initial Catalog=Northwind;" +
         "Data Source=localhost;Integrated Security=SSPI;");
    SqlDataAdapter customersTableAdapter =
        new SqlDataAdapter("Select * from Customers", connectionString);
    DataTable customerTable = new DataTable();

    // Fill the the adapter with the contents of the customer table.
    customersTableAdapter.Fill(customerTable);

    // Set data source for BindingSource1.
    BindingSource1.DataSource = customerTable;

    // Set the label text to the number of items in the collection before
    // an item is removed.
    label1.Text = "Starting count: " + BindingSource1.Count.ToString();

    //Access the List property and remove an item.
    BindingSource1.RemoveAt(4);

    // Show the new count.
    label2.Text = "Count after removal: " + BindingSource1.Count.ToString();
}
