DataRowCollection.RemoveAt Method

Removes the row at the specified index from the collection.

Namespace:  System.Data
Assembly:  System.Data (in System.Data.dll)

public void RemoveAt(
	int index
)

Parameters

index
Type: System.Int32

The index of the row to remove.

When a row is removed, all data in that row is lost. You can also call the Delete method of the DataRow class to just mark a row for removal. Calling RemoveAt is the same as calling Delete and then calling AcceptChanges.

You can use the Clear method to remove all members of the collection at one time.

The following example removes the last row in a DataRowCollection by calling the RemoveAt method.

Private Sub RemoveRowByIndex()
    Dim table As DataTable = CType(DataGrid1.DataSource, DataTable)
    Dim rowCollection As DataRowCollection = table.Rows
    If rowCollection.Count = 0 Then  
        Exit Sub 
    End If
    rowCollection.RemoveAt(rowCollection.Count - 1)
End Sub
