Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public:
virtual void InsertCopies(
	int indexSource, 
	int indexDestination, 
	int count
)

Parameters

indexSource
Type: System::Int32

The index of the DataGridViewRow on which to base the new rows.

indexDestination
Type: System::Int32

The position at which to insert the rows.

count
Type: System::Int32

The number of DataGridViewRow objects to add to the DataGridViewRowCollection.

ExceptionCondition
ArgumentOutOfRangeException

indexSource is less than zero or greater than the number of rows in the collection minus one.

-or-

indexDestination is less than zero or greater than the number of rows in the collection.

-or-

count is less than 1.

InvalidOperationException

The associated DataGridView control is performing one of the following actions that temporarily prevents new rows from being added:

  • Selecting all cells in the control.

  • Clearing the selection.

-or-

This method is being called from a handler for one of the following DataGridView events:

-or-

indexDestination is equal to the number of rows in the collection and DataGridView::AllowUserToAddRows is true.

-or-

This operation would insert frozen rows after unfrozen rows or unfrozen rows before frozen rows.

The InheritedStyle property of the new DataGridViewRow objects has the same values as the InheritedStyle of the DataGridViewRow positioned at indexSource. The InsertCopies method adds shared rows to the DataGridViewRowCollection, if possible. Otherwise, the new rows are unshared. For more information, see Best Practices for Scaling the Windows Forms DataGridView Control.

Rows in the control are not automatically sorted when new rows are added. To sort new rows into their correct position, call the DataGridView::Sort method in a DataGridView::RowsAdded event handler. You might also want to call the DataGridView::Sort method in a CellValueChanged event handler to sort the rows when the user modifies a cell.
