I couldn't find a right term to search about this in the feature.
I have a control that will load a very heavy data that embedding within a tab of of my MainWindow.
Test Case:
For testing I have a window, within this windows there are 2 tab. the first tab contain notthing. 2nd tab contain this user control.
In the 2nd tab I have a MessageBox.
Run this program and MessageBox popup right after the MainWindow was loaded.
How can I delay load this usercontrol/page until the tab is active?
Have you tried calling your load code only when the user control is visible?
The other suggestion would be to create you own tab control that only loads the content when the tab is visible. This would also allow you to create animations when a tab becomes hidden before the new tab is visible.

I'm developing an application in c# .net framework and I have a user control not developed by me that contains various buttons that when clicked show different kind of data and statistics (let's call it ucDataShow).
Such user control is in a different tab with respect to the main tab of my program (i'm talking about TabControl)
I'd like to create a button in my application that when clicked changes tab and shows the appropriate kind of data by simulating the click of the appropriate button of ucDataShow
Is there a way to do so?
you can change tabpage of tabcontrol like this:
tabControl1.SelectedTab = tabControl1.TabPages[n];
but i think it is not possible to raise click event of button which is on ucDataShow control.
I am trying to put a menu in the statusbar that is at the bottom of a custom user control.
When I click on the menu, it opens downwards, as usually happens with menus, with the result that the menu exits from the usercontrol.
How can I force the menu to open above the statusbar?
To open a context menu upwards, you must set the Placement property to Top:
ContextMenu.Placement = System.Windows.Controls.Primitives.PlacementMode.Top;
I'm creating a new winforms application.
I want to simulate MDI functionality with a flowlayoutpanel that will host "many" panels that will have a form embedded into it.
So the workflow would work like this:
User click on navigation menu to open a module (the module is a winform that will be embedded into a panel and this panel will expand to fill its container)
The user will se the module filled in order to work but has option to minimize it so he can work on other module.
When the user click on the minimize icon "custom icon added to the panel", the panel will minimize like a title into the flowcontainerpanel.
The user then can click on other module or double click the existing current opened modules "tiles" to open it again.
Here are some images so I can explain it better.
Once the "tile" is double clicked the panel should expand and fill:
How can I do this?
I've been all up and down this tutorial.
I can't for the life of me figure out how when my app loads to have 1 screen, then when a menu item is clicked to show another screen. I get the idea of having multiple forms, but is that the solution I need here?
From what I've read I understand new forms to be essentially new windows. If that's right, that doesn't sound like what I need.
My users start off with a blank window other than a menu (I'm gonna fill it in later), but I want for File -> Settings to load a settings form. Ideally not in a new window.
Its a MDI window. They are window containers of other windows.
You create a parent form, and then you change which child form is the active form on the menu item click events. This requires you make a parent MDI form, and a child MDI form for each of the different views you want of your document. The menu items then switch which child MDI form is the active one.
I'm creating a simple clipboard manager application. It monitors the content of a clipboard. When a change occurs (throu the win api message loop) it fires up a method to capture current content of clipboard and creates new object called clipboarditem. Next its building a ContextMeuStrip which consits of several clipboarditems created previously. The items menu is accessed by a hotkey. It shows up this menu on certain position of the screen itemsMenu.Show(caretPosition);, with .Focus(), I want it to make it disappear after it loses the focus (eg. clicking somehwere else on the screen or switch applications by alt-tab). Found an event OnLoseFocus but I dont think its working properly because the menu wont even show up.
How to make ContextMenuStrip disappear after loosing focus and how to prevent from showing ContextMenuStrip in taskabr ?
Sorry for my language skills :)
From a very quick look at the events that ContextMenuStrip contains, have you tried the "MouseCaptureChanged" event? It may help you with the losing focus issue.
For the showing in the taskbar issue, have you set "ShowInTaskbar" to false on the form you have your ContextMenuStrip (if you have it on a form)?
