Yes, if you wish to make the color change across sheets, you will have to do it manually. There is one workaround...make the change on one sheet, delete all of the corresponding objects ("selection menus") on the other sheets. Then, go to the object that you adjusted, hold down CTRL and drag it to each of the tabs. A copy of the object should be created in the same position on all sheets.
In QlikView 10, we are introducing Linked Objects, which will allow you to make changes to to one object and it will propagate out to all others.
Hope this helps!
Simple Solution: Suppose you want to change the color of SelectionsMenu, Change it in one sheet and Copy(CTRL+C) it. From rest of the sheets, just delete the Existing Menus and just Do (CTR+V) in each sheet. The good thing is that you dont have to adjust for Layout. It will be at same place as it was before.
Is linked object like the user controls in ASP.net, or Server Side Include in tranditional web development? I am from a web dev background sometimes find QlikView is not very strong at creating user defined and reusable components. Any suggestion?
And, is there something like PowerPoint slide master template in QlikView? So I can make one change (for example, adding a "Current User" label) on the master and then it is applied to all sheets?
I encountered the same issue. What you want to introduce in your dashboards is a color management system.
To get an idea what I mean I recommend you to check out the video in the blogpost QvM - Qlikview Modules.
Hope you find it helpful.
