Remarks

Use the RemovePotentiallyDangerousNavigateUrl property to validate the HyperlinkColumn values to prevent XSS vulnerability.

A secure URL starts with the “http:” or “https:” or doesn’t contain the ‘:’ symbol (relative URLs). Setting the RemovePotentiallyDangerousNavigateUrl property to true removes all potentially dangerous URLs from the <a> HTML element so it is rendered without HREF attribute. If the RemovePotentiallyDangerousNavigateUrl property value is set to Default, the hyperlink column’s navigate url vaidation depends on the BackwardCompatibilitySettings.RemovePotentiallyDangerousNavigateUrlDefaultValue property value.

Note

Note that grid-based controls validate only data source values used in the HyperlinkColumn column and ignore the HyperLinkProperties.NavigateUrlFormatString property.
