I am developing an application where I need to show the user all the images associated to a particular inspection. I want these images to be grouped and displayed from left to right just like File Explorer does. 

I would have thought PB would have this functionality but I am coming up empty. Has anyone ever developed this or am I missing something in PB (ie. Picture Control, etc)

Thanks,

Chris Craft

Hi Chris;

   Have you tried a LISTView control or DW object for this?

Can you control the images showing in a left to right order for a ListView or DW Object? I need it to display X number of images in a single row plus have some sort of group text above them. If I could use a DW Object that would be great but I do not see any options for this.

Hi Chris;

The User can align the images horizontally within a List View if you allow drag & drop - but, to control that aspect via PowerScript is very limited. My inclination for your implementation might be to look at either a CrossTab DWO or a group of User objects dynamically created via the OpenUserObject() command.

We do something like that.  The picture_name is the file path that is stored in the database and we use a computed column and use the bitmap function.  Seems to work pretty well for what we need.

 bitmap(picture_name)

Thanks Dennis - I was hoping to get the pictures going from left to right and have them auto move when expanded but it seems this is not doable. I will look at the Picture Control, ListView and DW to see which one is best suited for the task at hand.

Chris,

I wonder if setting it up with newspaper columns would take care of that.

Hi Dennis;

A good thought but, I do not think that that format will support what Chris is looking for. T he problem is to get a variable and continuous horizontal list of pictures. PB's controls are great at vertical lists for the most part.
