DataGridView.RowsRemoved Event
Occurs when a row or rows are deleted from the DataGridView.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
When rows are deleted from a DataGridView control, the index numbers of subsequent rows are lowered to compensate.
For more information about handling events, see Consuming Events.
The following code example demonstrates how to use this event to update the values in a balance column of a DataGridView. This example is part of a larger example available in the SelectionChanged event.
Private Sub CellValueChanged(ByVal sender As Object, _ ByVal e As DataGridViewCellEventArgs) _ Handles DataGridView1.CellValueChanged ' Update the balance column whenever the values of any cell changes. UpdateBalance() End Sub Private Sub RowsRemoved(ByVal sender As Object, _ ByVal e As DataGridViewRowsRemovedEventArgs) _ Handles DataGridView1.RowsRemoved ' Update the balance column whenever rows are deleted. UpdateBalance() End Sub Private Sub UpdateBalance() Dim counter As Integer Dim balance As Integer Dim deposit As Integer Dim withdrawal As Integer ' Iterate through the rows, skipping the Starting Balance Row. For counter = 1 To (DataGridView1.Rows.Count - 2) deposit = 0 withdrawal = 0 balance = Integer.Parse(DataGridView1.Rows(counter - 1) _ .Cells("Balance").Value.ToString()) If Not DataGridView1.Rows(counter) _ .Cells("Deposits").Value Is Nothing Then ' Verify that the cell value is not an empty string. If Not DataGridView1.Rows(counter) _ .Cells("Deposits").Value.ToString().Length = 0 Then deposit = Integer.Parse(DataGridView1.Rows(counter) _ .Cells("Deposits").Value.ToString()) End If End If If Not DataGridView1.Rows(counter) _ .Cells("Withdrawals").Value Is Nothing Then If Not DataGridView1.Rows(counter) _ .Cells("Withdrawals").Value.ToString().Length = 0 Then withdrawal = Integer.Parse(DataGridView1.Rows(counter) _ .Cells("Withdrawals").Value.ToString()) End If End If DataGridView1.Rows(counter).Cells("Balance").Value = _ (balance + deposit + withdrawal).ToString() Next End Sub
