How to close usecontrol window?

Question

I want the usercontrol window to close when the button on the usercontrol is clicked. How do I do this? I tried this.hide or this.dispose, but when I use them, the buttons in my form window are not visible.

Hi melisaonur-4906,
>>I tried this.hide or this.dispose, but when I use them, the buttons in my form window are not visible.

Are you referring to the button on the usercontrol?
I have two suggestions for you to refer to:

1. Add usercontrol and button controls by coding.
   You can refer to the following code: UserControl userControl = new UserControl();
   private void Form1_Load(object sender, EventArgs e)
   {
   Button button = new Button();
   button.Click += new EventHandler(click);
   userControl.Controls.Add(button);
   button.BackColor = Color.Red;
   userControl.BackColor = Color.Green;
   this.Controls.Add(userControl);
   }
   public void click(object sender, EventArgs e)
   {
   userControl.Hide();
   }

2.When adding usercontrol visually, make sure that the user control and the main forms have the same "using" references.

using DocumentFormat.OpenXml.Packaging;  
using DocumentFormat.OpenXml.Spreadsheet;  
using System;  
using System.Collections.Generic;  
using System.ComponentModel;  
using System.Data;  
using System.Drawing;  
using System.Linq;  
using System.Text;  
using System.Threading.Tasks;  
using System.Windows.Forms;  

namespace WindowsFormsApp  
{  
    public partial class UserControl1 : UserControl  
    {  
        ......  
        private void button1_Click(object sender, EventArgs e)  
        {  
            this.Hide();  
        }  
    }  
}  

Best Regards,

Try another instruction: this.FindForm( ).Close( ).
