Hi everybody,

Here is the code I'm trying for my UserControl for DefaultPicture property

[Bindable(true, BindingDirection.TwoWay), Category("User-Defined"), Description("Default Picture")]
public byte[] DefaultPicture
{
    get
    {
       // We need to convert picture to byte array 
        Byte[] imgByte = null;
        try
        {

            if (this.myPic.HasFile && this.myPic.PostedFile != null)
            {
                if (this.myPic.FileBytes.Length > 10240) // exception case
                    throw new Exception("Image File was is too big: " +
                            (this.myPic.FileBytes.Length / 1024).ToString() + " kB.");
                else
                    imgByte = this.myPic.FileBytes;
            }
        }
        catch (Exception e)
        {
            throw (e);
            //exception handled
        }
       return imgByte ;
    }

  set
    {
        if (this.pnlImage.Visible == true) 
        {
        //Here we need to set picture using JavaScript - ClientScriptManager    
        string Request_PhysicalPath = Request.PhysicalPath;
        string Request_FilePath = Request.FilePath;
        string dir = Request_PhysicalPath.Substring(0, (Request_PhysicalPath.Length - Request_PhysicalPath.Split('\\')[Request_PhysicalPath.Split('\\').Length - 1].Length));

        string[] delFiles = Directory.GetFiles(dir, "*aspx*" + Profile.UserName + "*.jpg");
        for (int i = 0; i < delFiles.Length; i++)
        {
            File.Delete(delFiles[i]);
        }

        string imgName = this.PersonID + Profile.UserName + ".jpg";
        if (value == null || value.ToString()  =="")
        {
            String dImg = dir + "icon_no_photo_80x80.gif";
            File.WriteAllBytes(Request_PhysicalPath + imgName, (byte[])File.ReadAllBytes(dImg));
        }
        else
        {
            File.WriteAllBytes(Request_PhysicalPath + imgName, value);
        }
        this.Page.ClientScript.RegisterStartupScript(this.GetType(), "ShowPic", "previewImage('" + Request_PhysicalPath + imgName + "')", true);
          //  picresult.src = Request_PhysicalPath + imgName; 
    }
}

And in my page I try

DefaultPicture = '<%# Bind("DefaultPicture") %>'

However, it gives me unhandled CAST exception when trying to convert DbNull to byte array.

How else can I handle this problem? Can I remove SET portion and create a public method instead and call this method to set this property? Or make set to be private and again use some public method?

Any ideas?

Thanks in advance.
