I want to display images, which i stored in the MSSQL 2008 with the type of varbinary, in a gridview.
I am using N-Tier to support my web application, i can get the image's value which is in binary type, but i do not know how to display it via a gridview.
how can i store image into database and view it in grid view?
View 3 RepliesI am using a list of objects as a datasource and passing the object into a user control. I use the code outlined below
[code]...
When I try to access the object this way, it's null.
Funny thing, I can access the user control and all the control data in the user control, but the object (both in the gridview and passed to the user control) are null.
I use image control in mypage that I bind it from database and I define that if there isn't any image in database it do Image1.visible=false
In chrome and firefox it worked correctly but in IE show like below
What should I do?

<asp:ImageField DataImageUrlField="photo" > <ItemStyle Width="50px" Height ="50px"
HorizontalAlign="Center" VerticalAlign="Middle" ></ItemStyle>

View 2 RepliesMaybe I'm looking for an easy way that just isn't there, but I'm trying to display the images I store in my SQL database in a GridView, and I just can't seem to get it right.
