Default image not shown in ASP ImageField

Allen Scott 2374 29 Jan 2015

In my asp.net gridview there's an ASP ImageField,When image is not shown or broken I need to show the Default Image, here I use NullImageUrl for this but this won't work.

My Code:

<asp:ImageField DataImageUrlField="FilePath" ControlStyle-Height="50" ControlStyle-Width="50" HeaderText="Image Preview" NullImageUrl="~/images/Defaultimg.png" />

<asp:Image class="fbimgsize" ImageUrl='<%#FormatURL(Convert.ToString(DataBinder.Eval(Container.DataItem,
"picture"))) %>'
  runat="server" ID="imgUser" />
public string FormatURL(string img)
    {
        try
        {
            if (Path.GetExtension(img).Equals(".jpg",StringComparison.InvariantCultureIgnoreCase))
            {
                return img;
            }
            else
            {
                return "images/noimage.jpg";
            }
        }
        catch (Exception)
        {
           return "images/noimage.jpg";
