BinaryImage issue with Null Values/Also no image displays

[Dwayne Starkey]

I have read the other posts talking about null values for binaryImages. None seem to work since I am programming in VB.
If my image from the DB is null I get the following:
Unable to cast object of type 'System.DBNull' to type 'System.Byte[]' “

If I do end up having an image, no image displays. I am retrieving the information from a stored procedure. All other information comes through fine except the image.
Any help would be appreciated.

Hello Dwayne,

Regarding the mentioned error: I tried replicating it in the attached sample but to no avail. Could you please check it out and let me know what differs in your case?

As it is to the image problem: Please make sure you have registered the http handler of the RadBinaryImage control in the web.config file as shown below and described in this help topic:

<httpHandlers>
      <remove path="*.asmx" verb="*" />
      ......................................................
      <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" />
</httpHandlers>

Sincerely yours,
