Firstly, I have a project with a Windows Form that references another project with WPF forms. The windows form has an elementhost which child is one of the WPF documents in the other project.
Now, on this WPF document I want to have a button that upon a click can open another wpf form. Either as a new standalone WPF form, as a modal or whatever.
I cannot, on the button click event, say
WPFform2 WPFform2=new WPFform2();<br>
WPFform2.Show();
... as many other threads on the net suggest, since the show method does not exist.
My solution does not allow some sort of call that changes the main Form´s elementhost, so that is not an option for me.
All my WPF forms derives from UserControl:
public partial class WPFform1: UserControl
The form must be derived from Window to have the Show() method.
Just create a new window that contains only the form you want to show and call Show on it. Or change the control's base class to Window (you will have to rewrite it both in XAML and in the code behind), nothing should really change, Window supports most of UserControl's features.

I'm trying to make a WindowsFormApplication in Visual Studio 2015 and need some help.
I've been trying to search for the answer on internet but can find out how to do the following:
I have two windows (solutions?). I open the second window with a button in the first one with this code:
this.Hide();
intermec prodinter = new intermec();
prodinter.ShowDialog();
My question is:
How can i "include" the second window (like "include" in PHP) instead of close the first window and then open the next one, like it does now?
A Form is just another Control. Think of it as a Container (because it holds other Controls).
A User Control can also hold more than one Control. There are ways you can display a Window inside another Window in a WinForms app, but the desired effect is not always guaranteed. So it would be best to place all of your controls (for "page 1", for example) in a User Control called "Page1", and then, when appropriate, add that User Control to the Form, and set its Dock property to Fill.
And when it's time to show a different "page", Hide(); "Page1", and Show(); "Page2".
I think you are talking about form inheritance:
Just create a form, lets call it as frmBase. And add some controls onto frmBase which you want to have on other forms as well.
Create other form, lets call it as frmDerived.
In the code behind of frmDerived, just do the following:
// derive the frmDerived form from frmBase
public partial class frmDerived : frmBase
{
public frmDerived()
{
InitializeComponent();
}
}
And then just check the frmDerived form design, it should include everything from frmBase.
And you may want to make the access modifier of some controls of frmBase to Public as required to access them on frmDerived.
I hope this will help you. :)
Is there any way to add a window form into another form as control? I do not want to change TopLevel = false while adding form as control.
OR
How can I use opacity property of added form as control when I set TopLevel = false?
It is not possible to put a windows form inside another.
But you can initiate another form another using ShowDialog() method. It feels like that parent form calling child.
UserControls provides the functionality add Controls on your page.
you can do all of this stuff with user control like opacity etc
You can't show a form in another form. You can have this functionality very easy, if you put all the controls on a UserControl. Then show that UserControls as a single control in a form and together with other controls on another form. That's pretty much easier than to try to have a form in a form...
Fischermaen - you can add a form to another form's control. Create a new class, but use references for the windows form. Make it a subclass of Form.
In the constructor you will need to edit the size and location of the form along with colors and whatever else you wish to modify.
In your main form use this:
this.Controls.Add(new newForm());
In an internet webpage , there is a constant menu usually placed on the top or left of a page from which user can navigate (They call it Iframes) ..
I would like to know if it is possible to do something like that using WinForm applications or WPF applications in c# .
At present I am simply inheriting forms from a base class . and each time the user needs to navigate , I have no option but to open up a new form with the same Peristent menu ...
Any suggestions here ?
I managed to use usercontrol to embed a form into another ..
Form1 has a userControl , Form2 embedded inside the user control .
things to note was ..
the embedded forms toplevel property should be set to false
the embedded forms FormBorderStyle should be set to none
userControl1.Controls.Clear();
Form2 f = new Form2();
f.Toplevel=flase;
f.Show();
f.TopLevel = false;
userControl1.Controls.Add(f);
You could use an MDI-container in WinForms.
see here and here for more information.
You mean like an MDI application (http://www.codeproject.com/KB/cs/myBestMDI.aspx) or just using a SplitContainer on the form? Really there are many options. WPF has ElementHost I think. Did you do any research yet? What did you find?
You could also take the toolbox approach. Have a parent program start the menu form and then other forms can use it... or it can launch from it... what ever your use case is.
Well, there should be a frame component in WPF which will give you such an option. Then you would use a "view" concept to open the WPF Pages you direct the user to.
I want to make an application that have one main form that have one functionality = Add new form.
I dont know how forms will be created, they are created dynamically by the user (AddForm methos from the main form).
All the subs forms are the same but some of thier prop receive differnce parameters (it can be in the ctor or later).
I want to be able to close all the forms when I close the main form.
Before new form will displayed I want to display setting form (to take the form parameters) maybe with ShowDialog method and do validating check on the form and just if the form validate the new form will displayed, if not (or if the user prees cancel) the form will disposed.
I know aboout MDI but I really perfer other way
Any ideas?
Thanks!
Closing all forms when main form is closed is somewhat easy, you just pass the main form reference in Show() method of the "child" forms; e.g. if you show child from main, you do:
child.Show(this);
This needs to be done if the your main form is not the real "main form of the program", but you want to close all "child" forms.
However, wiring all this together would preferably be done in some special class for this purpose, maybe called ScreenRepository. In this class, you would have a collection of open forms at any moment, you would deffer form creation to this class (so that this class automatically injects form parent) etc... Having this class would be easy to re-activate (give focus) the form if it is behind other forms, create new form if needed etc...
Idea is simple create a application that open a main form a the beginning and then open open other forms if needed if you close main form rest of forms are also closed. Like in GIMP.
lets say i have a main form which have a lot of functionallity.
this form have a tab control in which each tab contain some set of functionality.
what i want to do is when i click on each tab controls button i want to load a form into the client area of the tab control.
so instead of having a lot of controls in the main form , i will only have set of forms and each form will have its control.
i think this is will be better in term of managing the controls so i dont have like 150 control on the main form.
so basically i want to load a form on another form and not show the form in a seperate view.
if its not possible with forms then can i use another control that will group the controls and will be loaded on the main form?
thanks
Alternate 1 :
You can make each of the form as a User Control and then you can load the appropriate user control in a blank panel in your main form whenever required.
You should be able to find a way to communicate between your form and those user controls.
Alternate 2 :
You can show the appropriate Form using ShowModal() method, with the main form as parent, that way user can finish the work with the child form, before coming back to the main form.
Disadvantages here are user wont be able to interact with the main form as long as the child form is closed.
I would recommend looking into User Controls.
User Controls come with a designer, just like forms, and have a rich event model to tap into. Unlike forms, they are easy to embed into other controls and forms. As a matter of fact, user controls will show up in your toolbox to drag-and-drop onto another form.
It's at least worth taking a look at.
Following code adds one Form to a panel in another form.
Add this code in Form1
Form2 ff = new Form2();
ff.TopLevel = false;
ff.Dock = DockStyle.Fill;
ff.ControlBox = false;
ff.Text = "";
panel1.Controls.Add(ff);
ff.Show();
The flip side is your panel should be big enough to accomodate the form...
