I have a modal created for a WinForm that shows when user click the "Save" button. Instead of showing the MessageBox, I want to know if it's possible to incorporate a WPF control I've created instead? Here's my code.
Form frmModal = new Form();
frmModal.BackColor = Color.Black;
frmModal.WindowState = FormWindowState.Maximized;
frmModal.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
frmModal.Opacity = 0.6;
frmModal.Show(); //--> want to replace with WPF control
MessageBox.Show("Hello");
frmModal.Close();
frmModal.Dispose();
Yes you will need to bring up a new form window which uses a winform ElementHost control to show the WPF control.
Yes, you can use the customized WPF control in place of MessageBox, you can have a fairly good idea how to do it by referring to this CodeProject article for details: A Customizable WPF MessageBox
Hope this is what you are looking for.

I am not that PRO using WindowsForms because I do not use them too much but right now I am developing a Inventory system so this is my approach(design):
I have used 3 FlowLayoutPanels, I am trying to show various Forms inside FlowLayoutPanel3 when clicking specific button in the left panel the flowlayoutpanel3 will show/trigger the specific form.
What I have tried?, well I have read that I can use MDI container and stuff like that but I noticed that it is a different approach because I do not want to show a separate window, just just inside the flowlayoutpanel3 and maximized.
I have been googling solutions but could not find a solution. * OR is there any item in the toolbox to perform this kind of stuff?*
PD: I am using VS2019 and C#.
Create the new form, set it's TopLevel to false, add it to the panel controls and maximize it:
var frm = new Form(); //Or whatever form type you want to use.
frm.TopLevel = false;
frm.FormBorderStyle = FormBorderStyle.None;
flowLayoutPanel3.Controls.Add(frm);
frm.WindowState = FormWindowState.Maximized;
You may need also to make it visible
frm.Visible = true;
I'm trying to implement some complement views inside my application and I would like to have a better layout control over them. I don't know how to explain in words what my desired functionality is, so I made it through with some photoshop help, hoping you could give me a hand to implement it.
My application now looks like this:
(i need reputation to post images so.. sorry for the links)

When I minimize the modeless form which is focused in the previous image, I would like to be able to see it (and handle it to maximize or close) inside my main form as I show in the image below (made it in photoshop)

Hope someone can lead my into a solution and thanks for the support.
EDIT: I need to be able to move that form outside my main form, even to a different monitor.
If you don't want to use the MDI approach, then set TopLevel of the modeless Form to false and add it to the main Forms Controls collection before showing it:
Form frm = new Form();
frm.TopLevel = false;
this.Controls.Add(frm);
frm.Show();
*Obviously changing Form to the correct type of your modeless form.
If i understand what you are trying to do, you want to minimize a certain form but still see it within your app (im assuming like Excel or Word)
You can do something similar to what Idle_Mind said, but enclose both in a Form instead of the parent.
Form fParent = new Form();
fParent.Dock = DockMode.Fill;//i think this is the syntax. Use this if you want the form to fill to the screen
Form fChild = new Form();
fChild.TopLevel = false;
fParent.Controls.Add(fChild);
fChild.Show();
Here, it should minimize to the lower left part of the parent form. You can then size the parent to whatever you want it to be.
I'm looking at updating some existing code and making a popup modal which contains a custom user control and wondering if this is possible?
I know if I was to place the custom UserControl inside another form this could be achieved quite easily but this seems a bit overkill.
(CommentBox is the custom control)
CommentBox comment = CommentManager.GetComments(commentType, foreignID);
.//Some code to determine location of the popup
.
.
Popup popup = new Popup(comment);
popup.Show(grid.PointToScreen(viewerLocation));
If it has to be modal, then you have to use a form.
If you are just needing it to pop up over the form, then look into ToolStripDropDown and ToolStripControlHost to provide that ability. Here is an example: Padding/ Size / Margin, when using ToolstripControlHost for a popup control
I was wondering if anyone can help me with this rather baffling situation. I have a WPF form myForm which I am displaying modally in a WinForm application (without using an ElementHost). Everything works fine if I use the default WindowStyle and it is shown in the taskbar. However now I don't want the form to show in the taskbar or contain the minimize button, therefore I have done the following:
MyForm myForm = new MyForm();
myForm.ShowInTaskbar = false;
myForm.WindowStyle = System.Windows.WindowStyle.ToolWindow;
myForm.WindowStartupLocation =System.Windows.WindowStartupLocation.CenterOwner;
myForm.ShowDialog();
Now, the wpf form displays as expected modally and without the minimize button. If I now select the "parent" winform application in the taskbar, the wpf form disappears and there doesn't seem to be any way of returning to it! I have read this which is similar but not the same (pure WPF application), so I can understand why the main app does not appear in the ALT+TAB menu, but can anyone tell me how I can return to the wpf form?
Thanks in advance.
The use of WindowsInteropHelper allows you to wrap a hosted WPF-form using a Winforms-form and set its parent as a Winforms control, which prevents the WPF form from disappearing (as also pointed out by dowhilefor and Hans Passant)
E.g.:
// Use the interop helper for the specified wpf window hosted by the win32 owner
WindowInteropHelper wih = new WindowInteropHelper(wpfForm);
wih.Owner = this.someWin32FormsControl.Handle;
This is not related to Winforms or WPF, this is the way Windows functions. The only solution that I think you have is to wire up your modality; that is intercept the Activated event on your Winforms form and if your WPF tool window is visible, bring that window forward and give it focus.
Is their something like iframe in c#?
I want to build an application with one form that its content changes according to the actions I do, like messenger live. The part when I log in and log out its too different "windows" but it happens in the same form.
There is no iframe equivalent in winforms or wpf, but there are ways to deal with it.
For either winforms or wpf, what you want to do is have a Panel which you change the content of.
A panel is a container which holds/encapsulates other controls.
If you have two different views you want to toggle between, create two panels at the same position with the content you need. Then you will show one and hide the other. When the user executes some action which requires you to change the view, then simply hide the displaying panel, and unhide/show the other one.
Think of it as layers, where you will only show one at a time.
You can also dynamically load user controls into a panel, much like an iframe, but I find it easier to have the content in the form, and hide/show as needed.
Assuming WinForms, how about using UserControls? Place as many as you want in a single/multiple forms, and interact as you do in forms. See, UserControl class.
You can load a form into a Panel or tabPage from a TabControl:
Form f = new Form();
f.TopLevel = false;
panel1.Controls.Add(f);
f.Show();
f.Dock = DockStyle.Fill;
