Which is best practice to achieve change in look (color of top bar) based on a custom user profile property?

Property has value yes/no/null.

  1. Using pre init event to change masterpage dynamically? I am worried this technique will update show last updated master page if property is null.

  2. Loading the css file dynamically via user control.

  3. Any other method?

  • If it's only about changing the top suite bar color and assuming you're using on-prem, I would suggest using a Delegate Control and load it into AdditionalPageHead.

  • I was planning to use user control and apply the change theme based on property

  • If that's the case, the last logged in user will be overriding the theme. On each page refresh, theme will get updated.

  • Yes so current user will always get to see his theme because thats coded to check via user control in masterpage...

  • You'd be constantly updating the web w/ theme for every refresh for every user that falls within those N groups

You have below options:

  • OPTION 1:

Use a custom user control where you get the UPS property & based on the value register a script using


or some other way based on whether you are using Update panels in your control.

Basically you have to do below in the script file/function: using JQuery get the top bar HTML element & set the css using

$(".classNameofTopBar").css({background-color: Red});

Alternatively you can add a CSS reference from your code https://stackoverflow.com/questions/2943037/adding-stylesheets-programmatically-in-asp-net

You must finally ensure that you have CACHING enabled for your user control as it will fire every time. You need to consider performance too and I believe the UPS property wont change that frequently.

  • OPTION 2:

See whether the UPS property is exposed to the OOB SharePoint property loader control. In SP 2010 we can just add a reference to OOB user control & then use it in your JS code to set the color as stated above.
