Hello-

I have created a UserControl with the RadRotator on it and 4 buttons. 1 for Previous, 1 for View, 1 for Remove, and 1 for Next. All the buttons work except the Remove button. Here is my code to add images to the RadRotator:

                    foreach (FileInfo  photoFileInfo in m_photos)         
                        {         
                            Bitmap photoBitmap = new Bitmap(Image.FromFile(photoFileInfo.FullName), 313, 253);         
                     
                            RadImageItem radImageItem = new RadImageItem         
                                                            {         
                                                                Image = photoBitmap,         
                                                                Tag = photoFileInfo.Name         
                                                            };         
                     
                     
                            this.InvokeIfNeeded(() => photoRadRotator.Items.Add(radImageItem));         
                        }         

The Remove button calls the RemovePhoto Method. Here is the event handler for the delete button:

                    if (photoRadRotator.CurrentItem != null)         
                        {         
                            RadItem currentItem = photoRadRotator.CurrentItem;         
                            string fileNameString = currentItem.Tag.ToString();         
                     
                            foreach (RadItem radItem in photoRadRotator.Items)         
                            {         
                                List<RadItem> items = new List<RadItem>();         
                                if (radItem != currentItem)         
                     
                                    items.Add(radItem);         
                                ((RadImageItem) radItem).Image = null;         
                            }         
                     
                            photoRadRotator.Items.Clear();         
                            currentItem.Dispose();         
                            this.RemovePhotos(fileNameString);         
                        }         

Here is the code for the last line the RemovePhotos method:

                                if (!Directory.Exists(m_unusedFolder))         
                        {         
                            Directory.CreateDirectory(m_unusedFolder);         
                        }         
                     
                        File.Move(Path.Combine(m_associatedFolder, fileToRemove),         
                                  Path.Combine(m_unusedFolder, fileToRemove));         

I an error on the File.Move line that says the file is in use by another process. I have determined that the RadRotator i still holding on to the file through the Image property of the RadImageItem. I am trying to allow a user to look through a directory of photos using the RadRotator. If they find a photo they want to remove, they click the delete button and the photo is removed from the RadRotator and moved to another directory.

How can I programmatically remove an item from the RadRotator and then move it to another directory without the RadRotator still having a lock on the file?

Thanks,

Chance

Panel intto tab back to panel...

I'm brand new to your controls, and am just playing around with your examples.

I was looking at your dock examples.

After placing a Panel into a tab, I couldn't turn it back into a Panel.

Just wondering if there was a way to do this outside of your examples, or if its not really possible.
(or maybe I'm missing something)

Thanks.

How to set focus on GridView’s row in order to have keyboard navigation working?

I’m using RadGridView and GroupByExpression.
When displaying RadGridView items, I have managed to select specific group row but I don’t know how to give focus to current row so that keyboard navigation (up and down arrows) are working. Keyboard navigation only works when current row is mouse clicked.
I have tried something like this:

                    RadGridView.CurrentRow.VisualElement.Focus();          

but keyboard navigation still doesn’t work.

Thanks for help,
Tomislav

Saving Color Blending as Theme Package

I have a custom theme based on the Desert Theme. However, when alternating Grid Row Colors are enabled the color is the base orange and I cannot find that anywhere in the VSB. If I load the theme package in my application and do color blending then I can control the orange row color, but I would like to save the change back as theme package, so could you help me with one or the other of my two issues:

Direct me in altering the theme so the alternating row is not orange in the theme package.
Direct me to the equivalent save process for the LoadPackageResource

If you need an example please let me know
