I am overlaying a bunch of panels on top of one another. I want to be able to click a button to display which ever panel is in the stack referred to by unique names (panel1, panel2...).
However, the bottom panel some how is always the parent of whoever is on top of it. Therefore, If I were to set the visibility of the bottom panel to false, then nothing on top of the bottom panel can be made visible.
How do I make these overlayed panels independent to each other instead of having a parent-child relationship?
I faced the same situation a time ago. The more pragmatic way that I found was to use a tab control and hide/show tabs accordingly. It is possible to get rid of the label of the tab, so users dont even know about its existence. The rule is to have one and only one tab visible in any given time.

I have a wide "dock" area at the bottom of the screen. I have placed a UIFocusGuide across the top of it. Depending on which element in the dock has focus, the system may or may not have a focus solution if the user swipes up.
How can I tell my focus guide to use the system-calculated new focus item if there is one, but if not, it should use the one configured in my setPreferredFocusEnvironments:
Alternatively, is there a way to determine where a "swipe up" will take the focus without actually doing it? As the focused element in the dock changes, I could check this and if it has no destination provided by the system, I can add one.
My dock is a view within a main view controller but preferredFocusEnvironments is never called when the user tries to move to a non-existent view from an element in the dock.
This is my first UWP app
I have a SplitView. On the right side I want a menu. On the left side I want to be able to load different pages into it(frame)
The only menu I can find have that hamburger in it(AppBarButton).
This app will only run on windows desktop machines so I do not have need of the hamburger and it will be rather useless.
I have spent the last two nights looking for options but all I get are hamburgers.
Can someone please point me to an example of a no hamburger menu or a tutorial of some kind?
I am sure I can figure it out once I know what elements to use, I just need a push in the correct direction.
What you need is a base page (let's call it "HostView") this will simply have a SplitView control with the DisplayMode set to Inline and the IsPaneOpen set to true. You can also set the side panel width by using the OpenPaneLength property.
Your menu buttons go into the SplitView.Pane and you place a Frame control in the SplitView.Content. This frame will navigate to the correct page when a menu item is selected.
If you set the properties as I said above then you will not need a Hamburger menu to open the side panel at all. However, please consider the fact that users will want to resize your app, and they might resize to a very narrow size which means it might not have enough space to display all the content. IN which case you will need to collapse the side panel and show a hamburger menu to open it when needed. You don't have to do this, but it is something to consider.
I created an interface it has several forms you can switch between using a panel as the parent form. My problem is that when i switch between my forms on the second time i open a form if that form has autoscroll on a panel it will not allow you to scroll and the window is stuck on the view you previously had.
In this image i open the form internet. after doing so i will click on instruction( any form switch triggers this)
now i open the same form again and the scroll bar is gone and it locks in on the last position the form was in.
the very curious thing in this is that this only happens on the internet form word also has a scroll bar however even though the properties and settings for both are identical only one does not work.
What could be causing this and how do i go about troubleshooting errors like this.
The forms are removed from the panel and re-added, they are not closed.
Assumption 0:
The forms are removed from the panel and re-added, they are not
closed.
Store the state of panel autoscroll and set it after you have re-added it. Note that if you add controls to the panel first and panel is not docked, then scroll will not appear because panel dimensions can be huge. You should set following property as well:
vScrollBar1.Vericalscroll.Value = 0
Assumption 1:
I assume what is actually going on is that you do not add controls to that panel, but to the form behind it or something similar. In that case - program is correct, you just asked it to do a wrong thing.
Assumption 2:
Assuming is panel is anchored top, left, bottom, right. There is currently a limitation in Windows Forms that prevents all classes derived from ScrollableControl from acting properly when both RightToLeft is enabled and AutoScroll is set to True.

Assumption 3:
You add the controls back, by recreating them, but forget to add handlers or create them in order where scrollbar is out of view. Instead of absolute positions you could use dockstyle:
Dim vScrollBar1 As VScrollBar = New VScrollBar
vScrollBar1.Dock = DockStyle.Right
Controls.Add(vScrollBar1)
Short version: VB.Net Windows forms feature controls that are often dragged from the toolbox onto the form. The code for the control goes right into the form. Usually this is great, but is it possible to write the code for a UI control (like a panel) into a separate file which can then be imported or otherwise included into the main Form Class?
Context (a.k.a. long version): I have a form with an unchanging column of navigation buttons on the left hand side. The rest of the form is taken up by different panels, which in turn have different controls of their own. Clicking the different buttons on the left should cause these different panels to appear (clicking button "A" brings up panel "A"; button "B" brings up panel "B", etc.), but the left-hand menu should stay unchanged.
I'm having a hard time implementing this design in an elegant way in VB.Net. If I make each panel a separate Form, I have to duplicate the code that builds the unchanging left-hand menu in every file, which is terrible. I tried using inherited forms so the separate panels would inherit the left-hand menu from a master form, but that means each click on the menu sprouts the new form in a new window, and although the left-hand menu is inherited, the menu that I clicked and the identical-looking menu in the new window are not the same objects in memory and have no knowledge of each other.
I just want one window with central content that changes based on what you click on the left-hand side. A solution to this would be for the panels to be just that - panels - and not separate forms as I'm currently doing it. But this gets messy organizationally because the code for all of the panels has to be in the one massive master file. Hence the short form of my question (see above): How can I code a panel in a separate file and then bring it into the fold of the main form?
It sounds to me like you want to use usercontrols. Create a usercontrol for each of the four things you want and then add those to a panel, making each one visible or invisible according to which button was pressed.
I'd like to know how I can make a side panel which when collapsed only shows a button that upon click will be pushed out by an expanded area which contains a control of choice. Clicking the button again will collapse the expanded area and the only thing you'll see is the button at the edge of the screen again.
I don't have any good examples of something similar so I hope you understand what I mean.
in toolbox there is a control called Expander, which is exactly for that purpose
