Hi Sreenath G V,

As the document says the BackColor property does not support transparent colors unless the SupportsTransparentBackColor value of System.Windows.Forms.ControlStyles is set to true. By default the SupportsTransparentBackColor value of a form is set to false. To enable set transparent color for a form, you can set the SupportsTransparentBackColor value to true by inheriting from standard form.

Code Snippet

    public partial class MyBaseForm : Form

    {

        public MyBaseForm()

        {

            this.SetStyle(ControlStyles.SupportsTransparentBackColor, true);

            InitializeComponent();

        }

    }

 

Then you can use this base form as the base class instead of the standard form. This allows you set the transparent color to the form, but it won’t make the form transparent. To make a form transparent you can set the Form.TransparencyKey Property.

Best regards.

Answer 4

Excellent solution

put it before InitializeComponent(); of form

 

this.SetStyle(ControlStyles.SupportsTransparentBackColor, true);

Usually can be used in tandem with color picker

   this.BackColor = colorDialog1.Color;

 if (colorDialog1.ShowDialog() == DialogResult.OK) {

                this.BackColor = colorDialog1.Color;
                Util.gs_ThemeColor = colorDialog1.Color.Name;
             
            }

 

this.BackColor = Color.FromName(Util.gs_ThemeColor);
