hi all, just creating my first windows app have the below code

only problem is that it opens the form in a new window, i would like to have the form open in the same window

void _CompaniesFrm(object sender, ExecuteEventArgs e)
        {
            App.Companies.FrmCompanies obj = new App.Companies.FrmCompanies();
            obj.Show();
        }

Open in new window

No. Forms in a Windows application are seperate entities, they don't all draw within the same window as you would with a web page.

You can house the forms in an MDI window if you wanted to, but each seperate window would still display separately.

so an MDI window would give the apperance of them looking like their in one window though?

child forms go in the same window though dont they?

Thanks

Carl Tawn

The MDI window acts as a parent for the child windows. So each child will appear within the bounds of the MDI parent form, but they will still be separate windows.

This is worth a read to help clarify things:

that example is exactly what i needed, got it sorted now

is there a way i can hide/remove the title bar and menu so it looks like its the same page?

also is there a way i can change main forms

im guessing close one open another, but is there a way of that happening without screen flicker?

Thanks

i ahve the below but its being cheeky and showing up still

in form load i did the below both ways round (as i read it makes a difference) and it comes back with it almost but not quite each way

this.FormBorderStyle = FormBorderStyle.None;
            WindowState = FormWindowState.Maximized;

Open in new window

Hi awilderbeast;

To remove the title bar us the property FormBorderStyle as shown below

            NewForm nf = new NewForm( );
            nf.TopLevel = false;
            // Remove Border / Title bar from the form
            nf.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
            panel1.Controls.Add( nf );
            nf.Show( );

Open in new window

i dont like the animation between forms, i would like to click and it just be there, without looking like one is openeing and closing

can an application context do this?

Thanks

also thanks to fernado for the hiding border :)

If the forms aren't too complex, another option is to use one form with 2 panels on it. Put all the controls for the first form inside panel1, and all the controls for the second form inside panel2, put the two panels on top of each other, then change their visibility.

Alternatively use Show()/Hide() instead of Open()/Close()

ive tried show hide and open close, they both have animation on them instead of just a static transfer

the problem is im using windows Ribbon for WinForms, and i need a different menu ribbon depending on which section, but im not keen on the crappy animation that happens when you open close, show/hide a form :S

Hi, first you create one mdi form then when you click on the button of that form at that time write this code

childform objch = new childform();
objch.MdiParent = this.MdiParent;
objch.show();

it is working properly.
