Take a look at below code. private void button_Click( object senderRoutedEventArgse) { OtherWPFFormobj= new OtherWPFForm(); obj.Show(); } Here OtherWPFForm is another form which contains the user control in it. User Control code: button Content= Button HorizontalAlignment= Left Margin= 13115300 VerticalAlignment= Top Width= 75 /> textBox HorizontalAlignment= Left Height= 23 Margin= 13112500 TextWrapping= Wrap Text= TextBox VerticalAlignment= Top Width= 120 /> OtherWPFForm code which has user control in it. #FFF3F3F3 > Left Margin= 373600 VerticalAlignment= Top /> Finally the output is : Please mark it as an answer if it addresses the issue.

showdialog is the modal way to show the form means once it comes out you cannot click/access parent form while new form is opened. show is non-modal way to show form where it comes out as separate window allowing you to interact with your parent form at the same time. whichever suits your requirement. Please mark it answer if it addresses the issue.

That is something odd. In that case you need to create a form (with that usercontorl) and load that form because you cannot pop-out user control out of forms. It has to be WPF form with only user control in it and width and height of the form should be snapped to the height and width of user control.

If you are looking to do that by creating new object of the custom control then you need to be specific while adding the control to window. By specific I mean where you are adding the control. for example I have WPF main window with grid named maingrid and on button click I am adding the control as below. private void button_Click(object sender RoutedEventArgs e) { //either you can add control which is invisible and you make it visible at runtime usercontrol1.Visibility = Visibility.Visible; //or create a control and add it to children hierarchy as belwo. UserControl1 ctrl2 = new UserControl1(); ctrl2.Visibility = Visibility.Visible; maingrid.Children.Add(ctrl2); }

i also searched on the internet andit is said everywhere that i should change the visibility of the user control butnothinghappens with this for example in windows forms we say myform.show()or myform.showdialog(). whatshould i write instead of that here?

i don't want to show this user control in a grid of a main form. i want to show this user control individually and as a separate form not inside of a grid. i also changed the visibility of the user control to true but nothing happens
