Hello, i made a fileupload in aspx.

when i upload a photo (.jpg or .png) i can see in my database the value of my cell changes from NULL to <binary data>.

When i try to display the data in my gridview <asp:imagefield it display the 'missing picture sign'.

i selected right, and i tried to upload very small pictures, but nothing helps.
<asp:ImageField DataImageUrlField="ComLogo" SortExpression="ComLogo">
                <HeaderStyle Font-Size="20" />
                <ItemStyle CssClass="Discountlogo" Height="100px" Width="100px" />
</asp:ImageField>

I checked the file path.

If i in my selection string delete aspnet.ComLogo and type 'test', the test is displayed in my column. (I changed the imagefield to a boundfield).

And when i leave the aspnet.ComLogo alone in a boundfield, it displayes:

System.Byte[]
