How to set controls on center of the winform?

To set controls on the center of a WinForm in C#, you can use the Anchor property and SizeChanged event of the form to dynamically adjust the position of the control. Here's an example:

  • Add the control to the form: Drag and drop the control that you want to center onto the form. For this example, we'll use a Button control.

  • Set the Anchor property: Select the control, and set its Anchor property to None in the Properties window. This will allow you to programmatically adjust the position of the control.

  • Add a SizeChanged event handler: Double-click on the form to open the code-behind file, and add a SizeChanged event handler for the form:

private void Form1_SizeChanged(object sender, EventArgs e) { button1.Left = (this.ClientSize.Width - button1.Width) / 2; button1.Top = (this.ClientSize.Height - button1.Height) / 2; }
  • Update the control position on SizeChanged: In the SizeChanged event handler, calculate the new position of the control based on the size of the form and the size of the control. Set the Left and Top properties of the control to the calculated values.

In this example, the Left property of the control is set to the difference between the width of the form and the width of the control, divided by 2. This centers the control horizontally. The Top property of the control is set to the difference between the height of the form and the height of the control, divided by 2. This centers the control vertically.

When the form is resized, the SizeChanged event is raised, and the position of the control is updated to keep it centered.

Overall, centering controls on a WinForm in C# is a simple process that involves setting the Anchor property to None and dynamically adjusting the position of the control in the SizeChanged event handler.
