winforms - c# changing window size automatically -

i student working on windows forms application. in application have form pop window shows label. want change window's size according label's size. example if label has 3 lines, should show of lines automatically. right shows 1 line. how can fix problem?

you need calculate size of text using font settings of label in pop-up form. here's example of pop-up form's load event:

    private void popup_load(object sender, eventargs e)     {         messagelabel.text = texttoshow;          graphics gfx = this.creategraphics();         sizef textsize = gfx.measurestring(messagelabel.text, messagelabel.font);          size borders = this.size - this.clientsize;          this.size = new size((int)textsize.width, (int)textsize.height) + borders;                 } 

this code presumes have property called texttoshow pass message displayed form:

        public string texttoshow { get; set; } 

you can open pop-up form this:

        popup popup = new popup();         popup.texttoshow = "test\nmult-line popup window\n\nline4\n\nline 6";          popup.showdialog(this); 

the pop-up form scale label's size. try adjusting fonts, changing text, etc - should work correctly.

hope helps!
