how to use layout templat in asp.net wizard control?

i have read somewhere about using layout template in asp.net wizard control but when iam using the same in my code a parser error is generated

'System.Web.UI.Web开发者_JS百科Controls.Wizard' does not have a public property named 'LayoutTemplate'.

is there any way to solve this or is it true that it is not possible to use layout template in wizard control

i founded one answer that this (LayoutTemplate) is supported in dot net framework 4 and mine is 3.5 may be because of this.
