BindingManagerBase.RemoveAt(Int32) Method

Definition

When overridden in a derived class, deletes the row at the specified index from the underlying list.

public abstract void RemoveAt (int index);

Parameters

index
Int32

The index of the row to delete.

Exceptions

There is no row at the specified index.

Examples

private void button1_Click(object sender, System.EventArgs e)
{
   try
   {
      // Get the 'BindingManagerBase' object.
      BindingManagerBase myBindingManagerBase=BindingContext[myDataTable];
      // Remove the selected row from the grid.
      myBindingManagerBase.RemoveAt(myBindingManagerBase.Position);
   }
   catch(Exception ex)
   {
      MessageBox.Show(ex.Source);
      MessageBox.Show(ex.Message);
   }
}

Remarks

The RemoveAt method relies on the underlying data source to determine how the method behaves. (See the Binding class for a list of supported data sources.) For classes that implement IList, IBindingList, or ITypedList, as well as strongly typed classes that implement IList, the RemoveAt method actually deletes the row in the underlying list instead of removing its contents.

If the underlying list implements the IBindingList interface, the AllowRemove property must return true. If the underlying list implements the IList interface, the IsFixedSize property must return false.
