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

int IList.Add(
	Object value
)

Parameters

value
Type: System.Object

The DataGridViewCell to add to the collection.

Return Value

Type: System.Int32
The position into which the new element was inserted.

Implements

IList.Add(Object)

ExceptionCondition
InvalidCastException

value is not a DataGridViewCell.

InvalidOperationException

The row that owns this DataGridViewCellCollection already belongs to a DataGridView control.

-or-

value represents a cell that already belongs to a DataGridViewRow.

Once you add the row to a control, the number of cells it contains always matches the number of columns in the control, so this method is no longer useful.

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