i did a page where it shows data from sql database, where it is shown in a gridview. i can now then choose the id to be print or to show image in another tab.

my problem is the image data type in column. at it shows no preview icon.

the easy way is to set "nulldisplay" with a value "no image" if no image is attach[^]

else show a small picture like an icon or just show " with attachment" text if image exist.

thats my problem, where no settings is available for "notnulldisplay" = " with image"

take a look at this example.[^]

no code is necessary to show, clicking the gridview setting and configure the connection to the sql database.

additional info:
I'm using visual studio 2010, with c#,
the image is uploaded directly in the sql database as an image file.

This option is available with ImageField. Property is NullImageURL.

Hey the process you are following is called Smart Tag. But after you did so, it generates the markup for you on aspx page.

There is a ImageField. See the first image link you have given. Check the "Available Fields" section. The ImageField is there.

If you want to know more, then read - ImageField Class.
