RadRibbonView IsMinimized=true at startup, collapse of ribbon panel is delayed until after ContentRendered event

[PaulR]

Hi,

I'm using the RadRibbonView with IsMinimized=true at startup. We're noticing that the ribbon panel part is not collapsed until 'after' the ContentRendered event. As a result, for a brief moment, you can see the layout of the main window with the ribbon panel open and using the vertical space, and then quickly, the layout of the rest of the window shifts up as the ribbon panel is collapsed. It's a bit distracting.

To test:

- Add RadRibbonView with IsMinimized=true
- Override OnContentRendered in main window and put a breakpoint on the base.OnContentRendered line.
- Notice that the ribbon is not yet 'minimized' and is occupying space in the layout.
- Continue and it will minimize.

Hi Paul Raymond,

Following the described steps in your post, we weren't able to reproduce this behavior. Because of this, we would like to ask you for an additional information and a sample project so that we could examine your scenario.

1. Which version of our assemblies are you using in your application?
2. Which .NET Framework version are you using?
3. What is the OS of the machine where you run the application?

We are looking forward to your answer.

Hi,

So upon further investigation, it does seem intermittent. In my recent test, it would succeed (no delayed minimize effect), and then re-run and fail, then succeed, then fail.

I found that by adding the property "ContentHeight=0", this eliminated the problem completely. Thanks.

(For interest, I was on latest v613, .Net 4.6.1, Win10, VisualStudio2013 dark theme)

Hello,

I am dealing with the same issue.

the problem by setting the property "ContentHeight=0" is that afterwards the RadRibbonTab-Items are not visible anymore.

Any solution for this problem?

thanks

Hi Tobias,

I will need more information so I can better assist you. Can you send me an image which demonstrates what do you mean by the tabs are not visible?
