Ejemplos

En el ejemplo de código siguiente se crea un formulario DataGridView de Windows Forms con un y un conjunto de botones.The following code example creates a Windows Form with a DataGridView and a set of buttons. Cada etiqueta de botón describe una operación relacionada DataGridViewColumn con una propiedad, como el intercambio de la primera y la última columna DisplayIndex (mediante la propiedad) o el cambio del texto de un encabezado HeaderText de columna (mediante la propiedad).Each button label describes an operation related to a DataGridViewColumn property, such as swapping the first and last column (using the DisplayIndex property) or changing the text of a column header (using the HeaderText property). Al hacer clic en un botón, se cambia DataGridViewColumnla propiedad asociada de.Clicking a button changes the associated property of the DataGridViewColumn.

La DataGridViewColumn clase representa una columna lógica en un DataGridView control.The DataGridViewColumn class represents a logical column in a DataGridView control. Puede recuperar las columnas a través Columns de la colección del control.You can retrieve columns through the Columns collection of the control.

A diferencia de DataGridViewRowun, que contiene la colección real de celdas de DataGridViewun DataGridViewColumn , se usa principalmente para ajustar la apariencia y el comportamiento de la interfaz de usuario (UI) de la columna, como el ancho de columna y el estilo de celda.Unlike a DataGridViewRow, which contains the actual collection of cells in a DataGridView, DataGridViewColumn is used mainly to adjust the appearance and behavior of the column user interface (UI), such as column width and cell style. Para obtener más información sobre los estilos de celda, vea estilos de celda en el control DataGridView de Windows Forms.For more information about cell styles, see Cell Styles in the Windows Forms DataGridView Control.

Los tipos que derivan de DataGridViewColumn normalmente inicializan la CellTemplate propiedad en una nueva instancia de un tipo relacionado DataGridViewCell derivado de la clase.Types that derive from DataGridViewColumn typically initialize the CellTemplate property to a new instance of a related type derived from the DataGridViewCell class. Todas las propiedades de columna relacionadas con la apariencia o el comportamiento de celdas individuales son contenedores para las propiedades correspondientes de la celda de la plantilla.Any column properties that relate to the appearance or behavior of individual cells are wrappers for the corresponding properties of the template cell. Al cambiar una de estas propiedades en la columna, se cambia automáticamente el valor de la plantilla de celda y de todas las celdas de la columna.Changing one of these properties on the column automatically changes the value on the cell template and on all cells in the column. Para reemplazar el valor especificado para celdas individuales, establezca los valores de la celda después de establecer el valor de la columna.To override the specified value for individual cells, set the cell values after you set the column value.

Notas a los desarrolladores de herederos

Al derivar de DataGridViewColumn y agregar nuevas propiedades a la clase derivada, asegúrese de invalidar el Clone() método para copiar las nuevas propiedades durante las operaciones de clonación.When you derive from DataGridViewColumn and add new properties to the derived class, be sure to override the Clone() method to copy the new properties during cloning operations. También debe llamar al método de Clone() la clase base para que las propiedades de la clase base se copien en la nueva celda.You should also call the base class's Clone() method so that the properties of the base class are copied to the new cell.
