Hide Tabcontrol Buttons to Manage Stacked Panel Controls

Hide TabControl buttons to manage stacked Panel controls

You need a wee bit of Win32 API magic. The tab control sends the TCM_ADJUSTRECT message to allow the app to adjust the tab size. Add a new class to your project and paste the code shown below. Compile. Drop the new control from the top of the toolbox onto your form.

You'll get the tabs at design time so you can easily switch between pages. The tabs are hidden at runtime, use the SelectedIndex or SelectedTab property to switch between "views".

using System;
using System.Windows.Forms;

class StackPanel : TabControl {
  protected override void WndProc(ref Message m) {
    // Hide tabs by trapping the TCM_ADJUSTRECT message
    if (m.Msg == 0x1328 && !DesignMode) m.Result = (IntPtr)1;
    else base.WndProc(ref m);
  }
}

Moving controls from TabPage to Panel; controls being skipped

The collection is changing while you iterate them, so a simple trick is to go in reverse:

for (int i = tab.Controls.Count - 1; i >= 0; --i) {
  panel.Controls.Add(tab.Controls[i]);
}

or the one-liner:

panel.Controls.AddRange(tab.Controls.Cast<Control>().ToArray());

As other users have commented, probably better to just house each view in a separate UserControl instead of trying to move these controls — it will lead to spaghetti code trying to manage all those changes.

C# Button Tabs Hide Controls Winform

Put all your cheat controls in a custom UserControl and all your color controls in a different custom UserControl. You can edit the different control sets easily in the designer, and in your code you can hide/show them more easily by setting the appropriate UserControl's visibility rather than setting the visibility of a bunch of controls individually. Here's an (admittedly old) example of creating a UserControl: msdn.microsoft.com/en-us/library/aa302342.aspx

When you create a UserControl in Visual Studio, you can add the controls to it using the designer. In your form with the tab buttons, you would add instances of the two UserControls that you created. Since UserControl derives from Control, it has a Visible property. So, in your CheatControls(bool b) method, your implementation would be simplified to something like _myCheatControls.Visible = b;. I haven't watched the whole thing, but this video might help, too: youtube.com/watch?v=l5L_q_jI494

How do I create a Tab Control with no Tab Header in Windows form?

Use following code to hide the tabs or set these properties in design.

    tabControl.Appearance = TabAppearance.FlatButtons;
    tabControl.ItemSize = new Size(0, 1);
    tabControl.SizeMode = TabSizeMode.Fixed;

How can I disable a tab inside a TabControl?

The TabPage class hides the Enabled property. That was intentional as there is an awkward UI design problem with it. The basic issue is that disabling the page does not also disable the tab. And if try to work around that by disabling the tab with the Selecting event then it does not work when the TabControl has only one page.

If these usability problems do not concern you then keep in mind that the property still works, it is merely hidden from IntelliSense. If the FUD is uncomfortable then you can simply do this:

public static void EnableTab(TabPage page, bool enable) {
    foreach (Control ctl in page.Controls) ctl.Enabled = enable;
}

How to hide TabPage from TabControl

No, this doesn't exist. You have to remove the tab and re-add it when you want it. Or use a different (3rd-party) tab control.
