Hi,
I need to display some images uploaded in one aspx page into another.ie.,the user is entering his personal details and uploading his photo,id card copy,pancard copy ,etc in an application form .The administrator needs to view all the details entered by the user in another page.I am getting all the credentials entered by the user displayed except the images uploaded by him.But i am getting the correct ImageUrl while debugging.Anybody please help me to display the images.I am a beginner in asp.net development.I am using the following code snippet for displaying the image.

Updatepanel1.Visible=true;
Image1.ImageUrl=c.dr.GetValue(16).ToString();
Image1.Visible = true;

//c是声明连接字符串的类对象.
//div是SqlDataReader对象.

//c is class object where connection string is declared.
// dr is SqlDataReader object.

推荐答案

Image1.ImageUrl"com_addressproof \ 01.JPG";
您如何确定这是正确的URL?您看到的是带有十字的小矩形吗?如果是这样，那么这可能是形成相对路径的常见问题.

我建议您使用此技巧并在设置图像源之前正确解析路径:

Image1.ImageUrl "com_addressproof\01.JPG";
How are you sure this is the right URL? Are you seeing a small rectangle with a cross? If so, then this might be the common issue of relative path formed.

I would suggest you to use this Tip and resolve the path correctly before setting the image source: Resolving Paths in a Multi-Folder WebSite[^]
