I have created a Panel in Visual C#. At Runtime on page_Load event i added PictureBox to Panel dynamically. Now Picture added successfully to that Panel as follow

C#

private void Form1_Load(object sender, EventArgs e)
        {
            DataTable dt =controller.Category_SelectList();
            List<picturebox> pictureBoxList = new List<picturebox>();

            for (int i = 0; i < dt.Rows.Count; i++)
            {
                DataRow dr = dt.Rows[i];
                PictureBox picture = new PictureBox
                {
                    Name = "pictureBox" + i,
                    
                    Size = new Size(100, 100),
                    Location = new Point(i * 105, 1),
                    BorderStyle = BorderStyle.FixedSingle,
                    SizeMode = PictureBoxSizeMode.Zoom
                   
                };
                image = (byte[])dr["c_CatPhoto"];
                picture.Image = ByteArrToImage(image);
                picture.Name=dr["c_CatName"].ToString();
                Label lb = new Label();
                lb.Name = "label";
                lb.Text = dr["c_CatName"].ToString();
                lb.Size = new System.Drawing.Size(100, 40);
                lb.Location = new Point(i * 105, 105);
                
                //picture.ImageLocation = dr["c_CatPhoto"].ToString();
                pictureBoxList.Add(picture);
                pnlDisplayImage.Controls.Add(lb);

            }

            foreach (PictureBox p in pictureBoxList)
            {
                pnlDisplayImage.Controls.Add(p);
            }
        }
      
        public Image ByteArrToImage(byte[] brr)
        {
            MemoryStream ms = new MemoryStream(brr);
            Image img = Image.FromStream(ms);
            return img;

what is the primary key or unique key for the data?

C#

//create click event as below 
picture.Click += this.PictureClick;
//after add the picture to pictrebox 
pictureBoxList.Add(picture);

you can create event as below

C#

private void PictureClick(object sender, EventArgs e) {
    PictureBox oPictureBox = (PictureBox)sender;
    // if name is unique value for the data, you can get the name 
    // and find that name in your datatable
    string c_CatName = oPictureBox.Name;

}

if you have some other unique key column, try using Tag[^] property of PictureBox and set it as the unique key value, then you can get it inside event handler and take the details from datatable based on that unique key.
