I have a page which displays details and a pictures of employees. The details are stored in a SQL database and the images are on the server. How can I set a default Image to display (e.g. an Image saying "Awaiting Image") if an employee picture is missing?
I can't use NullImageUrl as the Images are not stored in the database. I can't use the solution found on [URL] as an ImageField does not accept an ID attribute.

I have a project that it had been developed under MVC1 and after aa few months ago I upgraded it in MVC2.
Everything was well, uppon the day I needed to format my computer.
And what can goes wrong with a format? I don't know
I have installed the MVC2, I build the project, no error displayed, but from the time I've uploaded the project in the production server
I am getting this error.
Method not found: 'System.Web.Mvc.MvcHtmlString System.Web.Mvc.Html.LinkExtensions.RouteLink(System.Web.Mvc.HtmlHelper, System.String, System.Object)'.
I can't understand what caused the problem.
Certainly I assumed that is have to do with MVC1 and I referenced it, but with no luck
again.
Theese are the methods that the problem is came from

I wasted the better part of the day on this and am no closer to a understanding the issue than what I was this morning.
I am looping through a set of objects and marking them for deletion. The 2nd one always causes the above exception. tb_invoice has a FK to tb_shipment.
As always, I am probably missing something very obvious, but I have stripped out so much from this code already that there is nothing left, and I am still getting this exception. This is a local SQL 2008 instance and there is of course nothing and nobody changing the invoice in between reading them and calling SubmitChanges().
myDataContext db = new myDataContext();
IQueryable<invoiceDetail> pendingInvoices
db.GetInvoiceDetailPending();
foreach (invoiceDetail id in pendingInvoices) {
tb_shipment s = db.GetShipmentById((Guid)id.shipment_id);
db.tb_invoices.DeleteOnSubmit(
db.GetInvoiceById(s.tb_invoices.FirstOrDefault().id)); }
SubmitChanges(); // fails for the 2nd invoice
}
I use to store image in bytes and able to convert it to system.drawing.image but not sure how to render it on page

The length 16 is used because this is the length of the field according to sql (the image datafield is a pointer of size 16) I noticed .Net is actually truncating the string because of the length i'm setting. An image of size 3kb will properly upload if we set the length field to be greater than 3kb The question I have is what is the proper value (or strategy) to use in order to set for the length field so that ALL images will properly update to the database, with each using the appropriate size.
I guess i could theoretically set the length to be maxint, but this seems sloppy. Looking at sqlparameter documentation i didnt see an 'unlimited' or 'default' length i could set, which would allow each update statement called to use the appropriate size for the data length for that row.
I am following the tut here[URL]

I have a problem with my chart image not refreshing and I narrowed it down to the fact that there's an unrelated image that according to MS VS2005 IDE, that the image file is not found... BUT..when I run/debug it... it displays properly.The image is right in the root of the aspx directory so it is not in any folder.<img src="right-thumb.png"> // this works but ide shows error and causes chart to have update problemi get an error in the IDE file is not found. however, if I display a FULL PATH, the problem goes away. WHY? i don't want to display the whole path because i don't want public users to see the server file location.
<img src="c:webapplication

i also tried
<asp:image runat="server" id="Image2" ImageUrl="~

and that too also has a problem! It underlines in red and says teh file is not there, but when i debug, of course it works and the image loads....
