Remarks

La propiedad HeaderStyle permite especificar el tipo de encabezado de columna que se va a mostrar cuando la propiedad View del control ListView está establecida en Details y el control ListView tiene ColumnHeader objetos especificados en el ListView.ColumnHeaderCollection.The HeaderStyle property allows you to specify the type of column headers to display when the View property of the ListView control is set to Details and the ListView control has ColumnHeader objects specified in the ListView.ColumnHeaderCollection. ColumnHeader objetos definen las columnas que se muestran en el control ListView.ColumnHeader objects define the columns that are displayed in the ListView control. Cada columna se usa para mostrar información de los subelementos de cada elemento en el ListView.Each column is used to display subitem information for each item in the ListView.

La propiedad HeaderStyle le permite especificar si los encabezados de columna son visibles o, si están visibles, si funcionan como botones en los que se puede hacer clic.The HeaderStyle property allows you to specify whether the column headers are visible or, if they are visible, whether they will function as clickable buttons. Si la propiedad HeaderStyle está establecida en ColumnHeaderStyle.None, no se muestran los encabezados de columna, aunque los elementos y subelementos del control ListView siguen dispuestos en columnas.If the HeaderStyle property is set to ColumnHeaderStyle.None, the column headers are not displayed, although the items and subitems of the ListView control are still arranged in columns. Si la propiedad HeaderStyle está establecida en ColumnHeaderStyle.Clickable, los encabezados de columna actúan como botones en los que los usuarios pueden hacer clic para llevar a cabo una acción, como la ordenación de los elementos del control ListView utilizando como clave los elementos de la columna en la que se ha hecho clic.If the HeaderStyle property is set to ColumnHeaderStyle.Clickable, the column headers act like buttons that users can click to carry out an action, such as sorting the items in the ListView control using the items in the clicked column as a key. Puede implementar este comportamiento en un controlador para el evento ColumnClick.You can implement this behavior in a handler for the ColumnClick event. Si la propiedad HeaderStyle está establecida en ColumnHeaderStyle.Nonclickable, aparecen los encabezados de columna, pero no se puede hacer clic en ellos.If the HeaderStyle property is set to ColumnHeaderStyle.Nonclickable, the column headers appear, but cannot be clicked.
