You can use a third party control that allows users to select an image, or you will have to implement functionality to browse the disk for the file.  Once you have the bits, you can assign the bits to the property of the entity and it will get saved to the database when you call SaveChanges().

Hi,

You can use below code to upload image to db using ideablade,

  OpenFileDialog openFileDialog1 = new OpenFileDialog();
        private void SelectFileultraButton_Click(object sender, EventArgs e)
        {
            openFileDialog1.Filter = "All Files (*.*)|*.*";
            openFileDialog1.Title = "Select File";
            if (DialogResult.Cancel == openFileDialog1.ShowDialog())
            {
                return;
            }
            fileNameUltraTextEditor.Text = openFileDialog1.FileName;
            string fileName = Path.GetFileName(fileNameUltraTextEditor.Text.ToString());
            byte[] content = ReadFileToByteArray(fileName);
            ImageUpload CurrentFile = bsFile.Current as ImageUpload;
            CurrentFile.File= content;
            CurrentFile.FileName = fileName;
        }
        protected static byte[] ReadFileToByteArray(string fileName)
        {
            FileStream fileStream = new FileStream(fileName, FileMode.OpenOrCreate, FileAccess.Read);
            long len;
            len = fileStream.Length;
            Byte[] fileAsByte = new Byte[len];
            fileStream.Read(fileAsByte, 0, fileAsByte.Length);
            MemoryStream memoryStream = new MemoryStream(fileAsByte);
            return memoryStream.ToArray();
        }

        private void saveToolStripButton_Click(object sender, EventArgs e)
        {
            if (PM.HasChanges())
            {
                try
                {
                    PM.SaveChanges();
                    MessageBox.Show("Sucessfully saved");
                }
                catch (Exception ex)
                {
                    MessageBox.Show(ex.Message.ToString());
                }
            }
            else
            {
                MessageBox.Show("Nothing to save");
            }
        }

Vinoth

Hi Bala,

No, i am not using any third party tools.

"ImageUpload"  is name of the table which included into ideablade object mapper with the same name.

using bellow step i am getting current item of the binding source, 

ImageUpload CurrentFile = bsFile.Current as ImageUpload;

And update the property of image column

CurrentFile.File= content;

Regards,
Vintoh
