Hello Surya,

Thank you for writing.

It is possible to achieve the drag and drop functionality from Outlook to RadGridView using the OLE drag-and-drop functionality. Here is a sample code snippet, demonstrating dragging an attachment from Outlook and dropping it to RadGridView. As a result a new row in the grid with the file name is inserted:

public Form1()
{
    InitializeComponent();
    this.radGridView1.AllowDrop = true;
    this.radGridView1.DragDrop += radGridView1_DragDrop;
    this.radGridView1.DragEnter += radGridView1_DragEnter;

}

private void radGridView1_DragEnter(object sender, DragEventArgs e)
{
    e.Effect = DragDropEffects.All;
}

private void radGridView1_DragDrop(object sender, DragEventArgs e)
{
    using (Stream o2 = (Stream)e.Data.GetData("FileGroupDescriptorW"))
    {
        using (StreamReader sr = new StreamReader(o2, System.Text.Encoding.Unicode))
        {
            string draggedFileName = sr.ReadToEnd();

            Microsoft.Office.Interop.Outlook.Application outlook = new Microsoft.Office.Interop.Outlook.Application();
            Microsoft.Office.Interop.Outlook.Selection sel = outlook.ActiveExplorer().Selection;
            foreach (object item in sel)
            {
                if (item is Microsoft.Office.Interop.Outlook.MailItem)
                {
                    Microsoft.Office.Interop.Outlook.MailItem mail = item as Microsoft.Office.Interop.Outlook.MailItem;
                    Console.WriteLine("Email from " + mail.SenderName + " Regarding " + mail.Subject + " " + mail.Attachments.Count);

                    foreach (Microsoft.Office.Interop.Outlook.Attachment attachment in mail.Attachments)
                    {
                        if (draggedFileName.Contains(attachment.FileName))
                        {
                            this.radGridView1.Rows.Add(attachment.FileName);
                        }
                    }
                }
            }
        }
    }
}

I would like to note that this is just a sample implementation and it may not cover all possible cases. Feel free to modify it on a way, which suits your requirement best. I think that "C# WinForms: Identify type of drag-drop action event" stackoverflow thread is useful about this topic.

I hope this information helps. Should you have further questions, I would be glad to help.
