Although each image has its image_id which is primary key and i want to open the link according to image_id. but my problem is how to find the image_id of each individual image.
so that i can open the respective file that i want.

Accepted answer
you have to take the field like suppose clicked image is opened in display.aspx:

runat="server"
PostBackUrl='<%# Eval("pname","display.aspx?pname={0}") %>'
ImageUrl='<%# Eval("pname","{0}") %>' />

now in display.aspx you can take query string like

display.aspx.cs

string s1 = Request.QueryString["pname"].ToString();
Image1.ImageUrl = s1;

hi.. You can pass image_Id and imageUrl this way...

runat="server"
PostBackUrl='<%# "display.aspx?ImgId="+Eval("ImgId")+"&ImageUrl="+Eval("imgurl") %>'
ImageUrl='<%# Eval("imgname","{0}") %>' />

display.aspx.cs

string imgid = Request.QueryString["imageId"].ToString();
string imgname = Request.QueryString["imgurl"].ToString();

Mark my answer if it helps you....
