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-

The DataSource property of the DataGridView is not null.

-or-

index is equal to the number of rows in the collection and the AllowUserToAddRows property of the DataGridView is set to true.

-or-

The DataGridView has no columns.

-or-

The DataGridView property of the value is not null.

-or-

value has a Selected property value of true.

-or-

This operation would insert a frozen row after unfrozen rows or an unfrozen row before frozen rows.

ArgumentException

This member is an explicit interface member implementation. It can be used only when the DataGridViewRowCollection instance is cast to an IList interface.

This method calls the Insert(Int32, DataGridViewRow) overload, passing in value after casting it to a DataGridViewRow.

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.
