HyperLinkColumn.DataNavigateUrlFormatString Property

Gets or sets the display format for the URL of the hyperlinks in the HyperLinkColumn when the URL is data-bound to a field in a data source.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public virtual string DataNavigateUrlFormatString { get; set; }

Property Value

Type: System.String
The string that specifies the display format for the URL of the hyperlinks in the HyperLinkColumn when the URL is data-bound to a field in a data source. The default value is String.Empty, which indicates that this property is not set.

Use the DataNavigateUrlFormatString property to provide a custom display format for the URL of the hyperlinks in the HyperLinkColumn. The specified format is only applied to the URL when the URL is data-bound to a field in a data source. Specify the field to bind to the URL of the hyperlinks in the column by setting the DataNavigateUrlField property.

For information on the syntax of formatting strings, see String.Format.

The following example demonstrates how to use the DataNavigateUrlFormatString property to format the data-bound hyperlinks in the HyperLinkColumn.
