Grid View Row Collection. Insert Copies(Int32, Int32, Int32) Method
Inserts rows into the collection at the specified position.
public: virtual void InsertCopies(int indexSource, int indexDestination, int count);
public virtual void InsertCopies (int indexSource, int indexDestination, int count);
abstract member InsertCopies : int * int * int -> unit override this.InsertCopies : int * int * int -> unit
Public Overridable Sub InsertCopies (indexSource As Integer, indexDestination As Integer, count As Integer)
The position at which to insert the rows.
indexSource is less than zero or greater than the number of rows in the collection minus one.
indexDestination is less than zero or greater than the number of rows in the collection.
count is less than 1.
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.
This method is being called from a handler for one of the following DataGridView events:
indexDestination is equal to the number of rows in the collection and AllowUserToAddRows is
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.
