So I have an odd issue while trying to use a WPF TextBox with SpellCheck enabled inside a Winforms form, using the custom control defined in this post.
This works just fine, I've tried using it in my own sandbox project and it looks great. The problem is when I try to replace the Winforms TextBoxes inside one of our existing forms. The SpellCheck context menu is "trapped" inside the control, so all I can see are the up/down arrows of the menu.
I'm not too familiar with Winforms, as I mostly work with WPF, so I'm having a hard time determining the problem. The text box shown above is the custom control as mentioned in the linked post. The control is contained in a forms TableLayoutPanel. How can I get the context menu to expand and actually be visible?
Edit
First, to clarify, the context menu appears normally when displayed in a console application that opens the form. I did a little more testing and created a new web project (what the original problem project is) with a button that opens the form, and then the problem behavior occurs. What difference between the console application and the web application would cause this?
Edit 2
I tried the suggestions in this post, thinking maybe the context menu really was just being automatically sized incorrectly (to fit the parent control). But none of those solutions seemed to make any difference either.
Edit 3
After using snoop to look at the differences between the working context menu (windows application) and the not-working one (xbap) the only difference I could see was that the DesiredSize of the xbap instance's context menu has a smaller size, I just have no idea why.
The wpf control is a control which is hosted in winforms via the ElementHost.
Hence it lives within the area provided by the parent.
The only way is to expand it, is to change the size of the parent. Give it a try by creating a winform supersized textbox as a quick debug example. Note whether the size change works on not. If it does can the GUI accommodate that change? I can't answer that.

I am doing my first steps programming a little toolbox in C#.
I want to choose the program to run via a menustrip.
How can I switch all visible textboxes, buttons etc. on the same form? I don't want to open a new form. Do I have to show/hide every element "by hand" or is there a better solution?
I hope you get my problem.
Thanks in advance.
Yes totally understood.
You need a way to navigate between different fragments within your application.
Since these are your first steps and not a legacy app, why aren't you starting with WPF which is the successor of Winforms ? (newer better)
See how can you achieve such functionally in WPF
https://learn.microsoft.com/en-us/dotnet/desktop/wpf/app-development/navigation-overview?view=netframeworkdesktop-4.8
Although the terms are similar and also apply in winforms.
What you want to do is to create all the buttons etc as part of a UserControl. You can then add your custom UserControl to the form. This should allow you to switch the user control for some other control, or change the visibility for the whole user control.
This can also allow you to place multiple user controls side by side or in some other layout.
As a learning project in C# .net I am re-creating a Gnome 3 plugin for seeing who of the streamers you follow on Twitch is live. I have the settings form done, I am now working on the interface that is viewed from a click on the taskbar.
This is a rough image of what I want the interface to look like. When two or more streamers are live the interface would add another block and resize the form vertically similar to the menu for selecting a Wifi network in Windows.
What would be the best way for me to complete this?
My current thought is to maybe create a custom control and just place those inside a FlowLayoutPanel with some kind of code to change the vertical size of the form to match the added entries. Maybe this can be done without a custom control and be done with code inside a FlowLayoutPanel? I'm not too sure.
Ideally I would also have a click event in the panel for each streamer so I could then open a browser to their channel. A slight highlight would also be a plus (maybe change the background colour based on mouse hover).
Thanks in advance for any suggestions!
i have create a few WPF applications in visual studio, and now i would like to create a final application to run all of the created apps in the final application. i would like to know how i can create a layout that displays the apps that are running inside the final app as buttons that can be clicked and cause the app to expand and allow the user to work on that app and then when finished return back to the final app and see the other apps to choose from. I imagine it would look like a Google chrome blank page that allows you see your familiar webpages and click on them to load them up. Any help or advice on what i should focus on to implement this would be much appreciated.
Thank you for taking the time to read over this.
Consider using a VisualBrush this takes other WPF UI (your "apps") and uses their UI as a brush for another UI element.
Raj Kumar has a simple article called Visual Brush in WPF for details.
The bit you probably want is at the bottom where he shows you rendering a controls content in another control. The magic being binding the controls visual to the element name whos UI it should render.
For instance, I have an application that has a main window and then child windows inside of it.
http://screenshots.rd.to/sn/e3hek/sapienfullwindow.png
http://screenshots.rd.to/sn/e3hek/appscreen8.png
What i need is to grab each individual child window of that application, and display them as tabs in my application, or on a panel's handle.
I already have code to kidnap the application and put it into mine, and it works great.
MDI support is already present in the C#. So the first screenshot is using the MDI option.
The second screenshot is using tabbed windows. Now you have two options:
Use this opensource library DockPanelSuite which will let you have tabs in your application. something similar to visual studio interface. You can create forms and then tab it based on your needs. You can even dock them anywhere in the parent form by drag and drop. Just like in visual studio.
The second option is to create a form with tab control covering the whole windows. There you create tabs using the resource editor and hide/show based on the forms you want to display to the end user.
In my opinion, use the first option which gives you lot more customization. Also if you use the dockpanel, you can switch between the views shown in your first screenshot and second one. So user has better control as to how he wants to view. Dockpanel is free to use even in commerical apps and comes with source code. So you can either use the dll or directly incorporate the code in your application.
I am trying to create a panel which will have a set of "buttons" on it.
These buttons should have the following behaviour:
Appear similar to a tag (with
rounded edges)
Contain a red
cross to remove the filter/tag from
the panel, similar to the way internet
explorer tabs have an embedded cross to close the individual tab.
allow the user to click
on the tag and respond like a normal
button (as long as the click is not
in the red cross)
Number 1 is no problem, this is just appearance, however, regarding numbers 2 and 3, I am not sure if there is already code out there do to something similar...and I dont really want to reinvent the wheel if I can avoid it!
My question is: Does anyone know if there is something out there in infragistics which will do this simply, or will I need to write this myself by subclassing winform buttons?
Thanks in advance!
Is this new development or maintenance of an existing project?
If it is maintenance, you have a somewhat tougher time ahead. You'll implement a UserControl, probably segmented into two buttons. Use docking to get the behavior as correct as possible. The far right button would contain your cross image; the left (which would need to auto-expand as you resize the control) would contain your primary button behavior. Play with the visual styles until you get them right (EG, removing borders, etc).
If this is new development, and you haven't gotten too far into it, you might consider using Windows Presentation Framework (WPF) instead of WinForms. It will be easier to build the control and get it to look exactly how you want it. WPF includes an extremely powerful control compositing system which allows you to layer multiple controls on top of each other and have them work exactly as you'd expect, and it carries the added advantage of allowing full visual control out-of-the-box.
Either way, this is more work than dropping in an external component ... I've used Infragistics for years, and I can't think of anything they have which is comparable. The closest, but only if you're building an MDI application and these controls are for window navigation, is the Tabbed MDI window management tools -- and there, only the tabs (which replace window title bars) have this behavior.
I don't think that infragistics can do something like this. The UltraButton control can't.
Implementing a own control wouldn't be that hard.
your probably going to have to make a costume control for this type of work.
