Hello,
I have a weird problem while displaying my image in "detail" section.
I have a specific routine to display my images in a column mode.
I pick up all data via a Web Service.
I display correctly information in the header section.
So when it comes to display pictures in the detail section here it bugs. For example if my dataset returns 2 images or more, i can see my orginal images duplicated many times.
Example 1 (with 1 image):
Image1 --> It works fine with one image
Example 2 (with 2 images):
Image1 Image2
Image1 Image2 --> here's the error. These images shoudln't be displayed
Example 3 (with 3 images):
Image1 Image2 Image3
Image1 Image2 Image3 --> here's the error. These images shoudln't be displayed
Image1 Image2 Image3 --> here's the error. These images shoudln't be displayed also!
Any help would be appreciated
Thank you
Paul

Have you tried debugging your code and verify how many times it goes into your if clauses and for how many rows from your datasource? Please investigate that and provide info on the culprit you notice. Also the detail section is printed once for every row in the data source, which is of course not true for the header section. Generally speaking the Report detail section works in similar fashion to asp:Repeater control, so you can try the same approach on aspx page with a repeater and elaborate on your observations.
