Namespace: System.Web.Configuration
Assembly: System.Web (in system.web.dll)

'Declaration
Public Overridable ReadOnly Property RequiresAttributeColonSubstitution As Boolean
'Usage
Dim instance As HttpCapabilitiesBase
Dim value As Boolean

Property Value

true if the browser requires colons in element attribute values to be substituted with a different character; otherwise, false. The default is false.

Some browsers do not recognize colons in element attribute values. If true, a different character will be substituted on rendering and returned in postback data.

The following code example shows how to determine whether the browser requires colons in element attribute values to be substituted with a different character.
