DataGridViewCellCollection::Clear Method ()
.NET Framework (current version)
Clears all cells from the collection.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
| Exception | Condition |
|---|---|
| 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.
