DEAR All,

I have problem in wpf application, In this task I have multiple images and slide control. I want it to fit when I resizing windows. My Image size must be minimum 100px. and margin between two images is 10px.

-when I resize windows first time it work fine. but when I change the slide control value then it shows blank space in right side of the panel it is not working properly.

- I want to remove space from right side and fit image in right blank space.

Any one have solution please let me know.

Thanks & regards

The windows design can be screwed up in many different ways. How can we know which of those ways did you choose. Could you show at least XAML? As a rule of thumb, the whole layout behavior should be fully defined by XAML, without any additional code behind.

if I Zoom-In the images/items using a slider. It would be great if you could provide some hint, how to make it work when we zoom the images - makes the images best fit in the window

This wasn't your original question. What's on these pictures? Could it possibly be a vector graphics? — I would highly recommend it.
