Hello there,
I have some question about working with RadScrollablePanel.

Sometimes the RadScrollablePanel does not correctly display the scrollbars. For example, I use RadLabel bounded by width of RadScrollablePanel (using the dynamically changeable MaximumSize property). 
I noticed that the vertical scrollbar does not always appear if the height of RadLabel and height of RadScrollablePanel.DisplayRectangle differ by about 10 pixels (at 96 DPI and Segoe UI 8.25pt font). This is clearly seen in example 1.
If we change width of RadScrollablePanel by a few pixels, we will see a different picture. A vertical scrollbar will be displayed on the screen and everything will look like it’s supposed to be. Keep in mind that the height of the elements remains unchanged. This is seen in example 2.
But that's not all. If we change the RadForm size a little more again, then we will see that the vertical scrollbar disappeared from the screen again; however, it's marked as Visible = True and if we take the focus on RadScrollablePanel, we can scroll the content using mouse wheel for example. This is seen in example 3.

Example 1: https://c2n.me/3ZabLEg
Example 2: https://c2n.me/3Zaclrf
Example 3: https://c2n.me/3ZacJol

At first sight, this may seem like a minor bug. However, considering that RadForms (or another container) with a fixed size can be used, and the text itself can change dynamically during operation, this bug causes problems with displaying information for users.
What guidelines can you give to work with RadScrollablePanel to prevent this bug?
Below I attach project with example. Please change extension from JPG to ZIP. 

I use Telerik 2018.3.1016.20 with .Net 3.5 on Win7

Best regards. 

Ok, so we have, like I said above, a scrollable panel, in a page view page and we are using Windows 8 theming in our application.  So, when we set all the controls on the form to that theme, any control that is in the Scrollable panel seems to get the back color from the page view page on which the scrollable panel is located instead of the back color from the scrollable panel.  This make our controls look weird. Attached is an example of what we are seeing.  You will see two scrollable panels, one on the form and the other on a page view page.  You can see the differences yourself.

This also happens if you use ThemeResolutionService.ApplicationThemeName = "Windows8" anywhere in our code as well

Hello,

Is there a way to disble the scroll when using the mouse wheel?

Hi,

have got to make this panel which contains a lot of group controls and I have run out of height on the winform..I tried using the scrollable panel docked to the form but no good (although it did allow some scrolling...how do I get a scrollable panel at design time where I can load all these controls?

Hi:

I am currently using the flowlayoutpanel in a Winforms application to build a horizontal timeline of thumbnail images.  This can contain several hundred thumbnails (as many as 500).   I've included a screenshot...

The problem with flowlayoutpanel (as well as the .net panel control) is that once the thumbnail layout becomes wider than 32,767 pixels, the control will no longer populate.   This is a big problem for my application.  Attempts to work around this have thus far been unsuccessful due to complexity and extremely poor performance.

Does Telerik have a scrollable panel that will allow me to populate with more?     If so I will purchase immediately!

Hi there,

i have the following problem:

I have a RadScrollablePanel.

 Inside this Panel i added two RadGroupBox-Controls.

The first is positioned in the upper left corner with Anchor = Left Top Right and minimum size of 300

The second is positioned in the upper right corner with Anchor = Top Right.

 Now when resizing my Form, i expected when the Minium size is reached, the Scrollable Panel should show scrollbar. 

I added an example project

Thanks Florian Keller
