DataGridViewComboBoxCell Class

Note: This class is new in the .NET Framework version 2.0.

Displays a combo box in a DataGridView control.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public class DataGridViewComboBoxCell : DataGridViewCell
public class DataGridViewComboBoxCell extends DataGridViewCell
public class DataGridViewComboBoxCell extends DataGridViewCell

The DataGridViewComboBoxCell class is a specialized type of DataGridViewCell used to display a combo box control, which is an editing field combined with a list selection field. The currently selected DataGridViewComboBoxCell hosts a DataGridViewComboBoxEditingControl in which the user can edit the cell's value, assuming the cell's ReadOnly property is set to false.

The DataGridViewComboBoxColumn is the column type specialized to hold cells of this type. To model the cells within a column after an existing DataGridViewComboBoxCell, set the column's CellTemplate property to that cell. By default, the CellTemplate is initialized to a new DataGridViewComboBoxCell.

The cell-related properties of the column are wrappers for the similarly-named properties of the template cell. Changing the property values of the template cell will affect only cells based on the template that are added after the change. Changing the cell-related property values of the column, however, will update the template cell and all other cells in the column, and refresh the column display if necessary.

Notes to Inheritors When you derive from DataGridViewComboBoxCell and add new properties to the derived class, be sure to override the Clone method to copy the new properties during cloning operations. You should also call the base class's Clone method so that the properties of the base class are copied to the new cell.

The following code example demonstrates how to use a DataGridViewCell as a template for a DataGridViewColumn. Style changes made to any cell in the column affect all of the column's cells. This code example is part of a larger example provided for the DataGridViewColumn class.

private void CustomizeCellsInThirdColumn()
{
    int thirdColumn = 2;
    DataGridViewColumn column =
        dataGridView.Columns[thirdColumn];
    DataGridViewCell cell = new DataGridViewTextBoxCell();

    cell.Style.BackColor = Color.Wheat;
    column.CellTemplate = cell;
}
