TabControl | Customizable Tab Control component for WinForms applications | User Interface library

As the title above, I want the page I've scrolled down to scroll back up when the BottomNavigationBar is pressed (double-pressed). I've managed to make it, no problem. But there is a problem if on the page there is contain a TabBar.

For Example I have a bottom navigation bar, that contains two pages:

HomePage and ProfilePage

On the HomePage I have a TabBar, and that contains two pages also:

FirstTabBarView and SecondTabBarView

The problem is when I've scrolled those two pages down (HomePage & ProfilePage at a different) I just want the FirstTabBarView view page to scroll to the top if I'm currently opening the FirstTabBarView page. But from my code, if I press the BottomNavigationBar button twice, both FirstTabBarView and SecondTabBarView both scroll up.

This is just a simple code sample, you can copy-paste and test it on the dart pad directly

I have a total of four tab items and the underlined rectangles have different widths depending on which of the four tab items is selected. But my data trigger binding doesn't work.

Expected：

Suppose I select the second tab item, and after I select the fourth tab item, the underline rectangle should move from the second tab item to the fourth tab item with the correct entry and exit animation as well as the correct width.

I have the following code but I don't know how to do it.

As I understand it, WPF "messages" (e.g. a button click handler) are added to an internal prioritized queue. A single UI thread is then responsible for processing the queued messages.

Unfortunately my knowledge of WPF is not deep enough to understand the internal working of the framework. So my question is, given that there is only 1 thread processing messages...

• What is the internal sequence of events (high level) that is leading to the tabs becoming unresponsive?

Observed Behavior

1. If you click slowly, the TabControl behaves as expected.
   • To reproduce: click 1 tab every 4 seconds.
   • It appears that if you give the TabControl.SelectedIndex data binding an opportunity to complete, the control will behave as designed.
2. If you click tabs quickly, then some of the tabs will become unresponsive.
   • To reproduce: click as many tabs as you can within 3 seconds.

Additional Reading

• Two selected tabs in tabcontroller
  • While the behavior is similar, this article is different because the symptom is the result of using a Tab + MessageBox.

Sample Code

The following code can be used to reproduce the behavior, whereby, WPF tabs become permanently selected.

Paste into MainWindow.xaml:

Why doesn't the scrollbar go down to the tab X (in Tab1) where the comboboxes are? The scrollbar is displayed, but it does not go down. There are no errors.

On the other hand, if I set scrollable_frame to comboboxes (as I think you should do it right), the comboboxes disappear and are not displayed

What am I doing wrong? Also is there something to fix in the code? Can you show me the code please? (with comments I may not understand) Thank you

I specify that I use Canvas and that I would like to use the tkinter widgets

I discovered Control.Parent may refer to either a Form OR it might also be a Page if it's in a TabControl. In the past, I've simply snagged the parent, and it was a form, even for controls on tabs. What's confounding me more, is subform controls appear to have the Form as .Parent, but no other controls do (note, this may not always be true as indicated by @FunThomas); but it is the case in my version of Access).

MSAccess's Control.Parent Documentation while being fairly terse, just says "Returns the parent object for the specified object." Some research has stated the control parent is the form, even for controls on tabs, so I'm more confused. Even Microsoft's page on referring to controls says either are valid, which makes me wonder if this ever worked in the past, or I'm just imagining it.

Given a Form named TopForm, and a TabControl named TabCtl1, a Page named TabPage1, and various controls (SubForm, TextBox, etc.) are on a Tab Page in a form, the following appears to be the case.

This question is related to an answer I gave over here, and is asked to flesh out an edge case I discovered while implementing the solution for my use.

Note: ALL controls in this case are on a "Page" (Subform is on another tab page because reasons):

Control Type Control.Parent Returns Parent Type Expected Parent TabCtl1 TopForm Form TopForm TabPage1 TabCtl1 TabControl TabCtl1 TabPage2 TabCtl1 TabControl TabCtl1 SubFormCtl TopForm Form TabPage2 ListBoxCtl TabPage1 Tab Page Tab Page 1 TextBoxCtl TabPage1 Tab Page Tab Page 1

And now, the question: What am I doing wrong? Do I need to loop through all the parents until I get the Control's parent form?

I have TabBarView into TabBarView like following

I have a TabControl with a couple of static TabItems. I am now trying to dynamically add some tabs with a custom ItemTemplate and ContentTemplate.

Something like this:
