Hi

I began reading this amazing book and I'm vary pleased with it.

I just need help with something...

I have created a Parent master.page and 2 Child master.pages that inherit from the Parent.

Each Child master.page is used to load a completely different StyleTheme to my website.

Inside my Parent master.page I have inserted a DropDownList control with the names of the 2 themes.

Now what I want to know is what code in C# can help me switch at runtime between the 2 child master.pages whenever a user clicks on the dropdownlist.

Thanks in advance

Hi there,

Take a look here: http://stackoverflow.com/questions/3...es-master-page

BTW: make sure both master pages have the same set of ContentPlaceholder controls.

Cheers,

Imar

I have been building my website in accordance with the teachings of the book.

The styles to my website are set from the ( App_Themes ) folder. Inside the ( App_Themes ) folder I have 2 themes – Light and Dark.

I also have 1 Parent Master.page and 2 Child master.pages and each child master.page loads a different style to the website.

I don’t know if I’m thinking right here - but is it possible to change programmatically the theme from the ( App_Themes ) and Child master.page with single DropDownList or is it only possible to change one at a time???

Thanks in advance.

Yes, you can do it at once as you need to switch both themes and the master page in the PreInit method....

Cheers,

Imar

Thanks for your reply mr Imar

If I may ask - Back in chapter 6 where you first start to explaine how to switch between themes, you insert some code logic inside ( Frontend.master.cs ). In your example you had only 1 Master.page.

Now in my case where I have 1 Parent and 2 children - Am I right to assume that code will go inside the parent master.page code behind and not inside one of the child master.pages.

Thanks in advance

Yes, that way you only have to write the code once.

Then in the BasePage you can apply the selected master page as well as the selected theme....

Thanks again for clarifying that Mr. Imar
I'm sorry to keep bothering you with this it's just that I keep have some trouble getting it to work.

So if it’s ok could you please clarify one more thing to me?

I have created 4 aspx.pages that inherit from the darktheme Child master
• Home
• About
• Work
• Contact

Is it possible to switch the inheritance of these aspx.pages from ( Dark child master.page ) to ( Light child master.page ) or must I create 4 additional aspx.pages that inherit from the light master.page?

Thanks once again

May I ask a question in return? Why don't you just try it out? The best way to learn is to experiment. The article I linked to showed you exactly how to switch master pages at run-time and I have provided other information in this thread of stuff you need to be aware off.

So, try it out, and you'll see that it works.

Imar

I'm new to this Asp.net and it goes without saying that I will need to experiment on this as I have for hours now :)

I just thought that I might be a good idea to ask and make sure that I'm not thinking wrong while beliving that my computer is messing with me.

Thanks

In that case, rather than posting questions like "Can it be done?", what about posting questions like: "I have been experimenting with this and that in order to accomplish such and so. However, when I try such and so, I run into error X. Here's the relevant code I am trying to get to work, as well as the error message I am getting"

That way, it's way easier to help you figure this out ;-)

Cheers,

Imar
