Qu'est-ce qu'un lien hypertexte ?
Un lien hypertexte est un élément tel qu'un mot, une phrase ou un objet qui pointe vers un autre emplacement. Lorsque vous cliquez sur un lien, vous accédez à la cible de ce lien.
Dans le contexte des classeurs pour .NET, un lien hypertexte est un mot ou une phrase dans une cellule ou une plage de cellules donnée.
Le Lien hypertexte encapsule l'objet qui représente un lien hypertexte et possède les propriétés suivantes :
CellRange: the range of cells where the hyperlink is applied.DestinationAddress: the destination address of the hyperlink.TextToDisplay: the text that should be displayed if the existing text is to be replaced. The default value will be the DestinationAddress if no value is provided when the item is created.Tooltip: the text that will be displayed when the user mouses over the hyperlink’s cells range.Type: the hyperlink's type, supported values are:Email: the hyperlink refers to an email address.ExternalFile: The hyperlink refers to an external document.Internal: The hyperlink refers to a Cell in the current Worksheet or from another Worksheet of the Workbook.WebSite: The hyperlink refers to a website.
Accès aux hyperliens
Les liens hypertextes d'un classeur sont accessibles par le biais de la fonction Collection de liens hypertextes sur un Feuille de travail.
Le Collection de liens hypertextes contient tous les hyperliens de la feuille de calcul. Elle permet également à l'utilisateur d'ajouter de nouveaux hyperliens et de les manipuler.
Le Collection de liens hypertextes possède les propriétés suivantes :
