Is there a way to inject a panel with a custom scrollbar?
I have the following issues with the current scrollbar:
the software I create has to work on both Compact framework and full framework
on the cf a touchscreen is attached and the default scrollbars aren't touchscreen-friendly
On the full framework the behavior of the scrollbars is sometimes strange.
All the controls are skinnable in the application, and so is my current custom scrollbar, but the looks of the default scrollbar doesn't fits with all the skins.
One way is to have 2 panels as one custom control and move the one over the other, but I prefer not to implement it that way becaus of all the overhead.
You have to bear some overhead with this approach. Set the "AutoScroll" property of Panel to false. Set a VScrollBar and process it with the Panels resize events.

I have this GUI for my Winform application with 2 FlowLayoutPanels Docked top and right respectively.
Right now I can only give them a fixed size which cannot be changed by user at run time but I want to make these panel Resizable while the application is running.
I've tried BorderStyle Property but only available options are Fixed3D and FixedSingle which are obviously cannot be resized due to their Fixed! behaviour.
I've already gone through the documentation at MSDN but couldn't find anything.
I want to know if I can make them resizable programmatically?
I need to rotate my custom control in Windows Form using C# without using third-party libraries.
Don't want to either rotate the text or image of control instead actually need to entirely rotate control.

You can't rotate controls. That's simply not supported by the native API controls that WinForms uses.
And one might wonder why it even should be supported. What could you possibly be trying to do that you'd need to rotate a button control? It would be much easier to draw it in a different place with a different shape in the first place, rather than trying to rotate an existing control. (Do note that you can also resize and reposition a control at run-time, if that would fit your needs. Investigate the Size and Location properties.)
The only workaround is to draw the control's image to a bitmap, hide the control, and draw the bitmap onto the form in the location you want it to appear. Of course, that won't result in a control that the user can interact with. They won't be able to click an image of a button, because it's not a real button. If that's acceptable to you, you should probably be using an image in the first place, rather than a button.
It is possible if you can get control of the painting, but you have to do a lot of the work yourself. Basically it all occurs on painting. A good example demonstrating how to do it is the Dock Panel Suite for WinForms.
In the VS2005AutoHideStrip (found here), there is a GetTransformedRectangle method that uses a System.Drawing.Drawing2D.Matrix class to rotate a rectangle.
It also sets the Transform property on the Graphics class, which will apply transformations automatically when you ask for something to be painted.
I advise reviewing this code for examples, it does it to draw docked tab strips down the sides of the page as opposed to top / bottom.
Some controls like TextBox are funny in that they borrow heavily from low-level Win32 libraries in their painting / behaviour, I've no idea if it is possible to get enough control to rotate this.
It is not possible to rotate controls. This is not supported by WinForms' controls API.
As you are dealing with a custom control, try simply redrawing it to suit your purposes.
I am pretty sure you can not perform this in windows forms at least not easily. However you can perform this in WPF and then bring WPF to your windows Form if you are looking for cool designs or even special effects to your controls.
This is FAR more easily done in WPF. In Windows Form, it's a huage pain to pull off.
Hope this help
In the most basic sense, what is a Tab Control?
I am looking into creating one from scratch (I have many good reasons for this and simply extending existing ones won't make me feel better). But I am not sure how they are made.
Is a Tab Control just a bunch of Panels, inside a main Panel? Here's a picture of what I mean...
At it's core, TabControl is a very simple control. Nothing but a row of rectangles with text on them. It is Winforms that adds the TabPage class, a scrollable container control that adds the ability to hide controls. Derived from the Panel class.
It bulks up with features that you can arbitrarily drop. Like rendering in a way that's compatible with the active visual styles theme that the user selected. And dealing with an app that asks for more tabs than can fit in a row. And implementing both keyboard and mouse navigation. And implementing transparency so the parent window content is visible behind the tabs.
It is so simple that the need to implement your own is rare :)
I am building an app that uses some built in and some 3rd party controls (DevExpress).
Inside the designer, everything looks OK, however while running the app, some controls are placed wrong.
Are there any easy ways to debug this issue?
More specifically, i have a container that holds 2 controls in it.
These controls should stack nicely together one on top of the other (indeed it looks like that in the Designer).
While running the app, one control is displayed on top of the other blocking it (see attached image).
Another weird thing is that some properties of the 2 controls that get overlapped are not updated with respect to their visual status.
this means that a control has a Location of (0, 300) but in fact appears to be in (0, 0).
As a workaround, you could place the two controls in the two panels of a SplitContainer and dock (fill) them there. This has also the advantage that the users can resize the controls.
Another alternative is the TableLayoutPanel.
I'm making a custom GUI for my application. Basically my application has multiple 'tabs'. Each tab has a panel control binded to it, to display tabs contents. Whenever any of the tabs are clicked, appropriate panel control becomes visible (that displays contents) and the rest of the panels become invisible.
The problem is that when I design them in Visual Studio, it's hard to work, ether panels are stacked up on each other or I put them in different coordinates, and when panel becomes active, it's location is updated.
Is there I way I could design all the panels, like on separate 'form' or something like the same way I have separate classes? if that makes sense. Thanks!
EDIT:
I can't use the standard tab control, because my application has custom GUI, all buttons and everything is designed in image processing app. Tab control doesn't allow me to use my own graphics.
I'm going to take a look at UserControl, thanks everybody!
You can create each tab content in a separate UserControl. Use that each UserControl as the only content on each tab.
You should be able to design each "panel" as a separate UserControl.
Your main Form can just be composed from those UserControls, instead of having the entire UI built into one class.
First I would suggest you stick with the standard .NET controls in most cases. Particularly in this case the standard TabControl seems to be a good fit.
That said, you can place all the panels on the form in their final location (being sure not to place a panel within the other panel). You can then use the drop down in the Properties dialog to select the Panel you wish to work with. Next go to the Format menu and choose Order->Bring to Front. This will bring the wanted panel to the front so you may use the designer on it. You can then continue to hide or show the appropriate panels at runtime.
