I am trying to display the images from Project folder(solution explorer) to datagridviewimage column cell.

i got the following error:

An exception of type 'System.IO.FileNotFoundException' occurred in System.Drawing.dll but was not handled in user code

Additional information: ~/images/pdf.png

i stored the images in solution explorer

What I have tried:

void gvProduct_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)

           if (e.RowIndex > -1 && e.ColumnIndex == this.gvProduct.Columns["Calibrateimg"].Index)
               if (this.gvProduct["CalibratCertificate", e.RowIndex].Value != null)
                  // string s = this.gvProduct["CalibrationCertificate", e.RowIndex].Value.ToString();

                           string Calibaration = gvProduct.Rows[e.RowIndex].Cells["CalibratCertificate"].Value.ToString().Trim();
                           string targetPath = System.Windows.Forms.Application.StartupPath + "\\App_Data\\CalibrationCertificate\\";

                           string extn = Path.GetExtension(Calibaration);

                           // read the file data
                           switch (extn)
                               case ".pdf":
                            MessageBox.Show("test img");
                           e.Value = Image.FromFile("~/images/pdf.png");

                               case ".docs":
                                   e.Value = Image.FromFile("~/images/word.png");


<pre> public void BindGrid()
            DataSet ds = new DataSet();
            ds = BindData("BindProduct", this.branch, string.Empty);

            DataGridViewImageColumn img = new DataGridViewImageColumn();
            img.Name = "Calibrateimg";
            img.HeaderText = "Calibrateimg";

            if (ds.Tables[0].Rows.Count > 0)
                gvProduct.AutoGenerateColumns = true;
                gvProduct.DataSource = ds.Tables[0];

                this.gvProduct.Columns["CalibratCertificate"].Visible = false;

                this.gvProduct.CellFormatting += new DataGridViewCellFormattingEventHandler(gvProduct_CellFormatting);

If you're including it as part of your project/solution and want it deployed with your executable then you probably want to look at using embedded resources. At compile-time these will get embedded within your exe and remain accessible to the application at runtime.

This StackOverflow answer explains it[^] quite well, you just need to change the images "Build Type" to embedded resource, and then you can access those resources programmatically.
