Use this code and click the save icon: 

        public RadForm1()
        {
            InitializeComponent();
            this.radImageEditor1.ImageSaved+=radImageEditor1_ImageSaved;

            this.radImageEditor1.OpenImage(@"..\..\London_01.jpg");
        }

        private void radImageEditor1_ImageSaved(object sender, EventArgs e)
        {
            RadMessageBox.Show("Saved!");
        }

You will notice that the ImageSaved event is not fired.

1. To reproduce use an image with horizontal and/or vertical resolution different from 96.
2. Open with with RadImageEditor.
3. Check this.radImageEditor.CurrentBitmap.HorizontalResolution and you will see that it has a value of 96.

1.Load an image to RadImageEditor and click the save button:

2. Enter the file name and select .jpeg extension:

3. Even though the file is saved as .jpg, its stores .png content:

When I select Auto option in zoom drop-down list the image will not be resized to fit available space. The only way to auto-fit the image is to type "Auto" in drop-down list. Also, when editor form is resized while "Auto" option is selected the zoom will not be updated.

Additional methods OnResize and DropDownList_SelectedIndexChanged are required to update the zoom, because in DropDownList_TextChanged event handler this.dropDownList.SelectedIndex is always set to -1 when any option is selected with mouse, and will be different from -1 only when a text matching an option is entered with keyboard.

For the first time, I tried to use the ImageEditor.

Open a 6000x4000 pixels file.

Click on Sharpen tool.

Click on the numeric up-down widget to go from 0 to 1.

Result: CRASH

An unhandled exception of type 'System.OutOfMemoryException' occurred in Telerik.WinControls.UI.dll

What happens ? Component limited in dimensions ?

OS has 16GB of memory. 

Thank you in advance,
