DataGridViewCellCollection.Clear Method

Clears all cells from the collection.

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

public virtual void Clear()

ExceptionCondition
InvalidOperationException

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

Use this method to alter the collection before you add the containing row to a DataGridView control. 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.
