image size

Hello Lily,

According to the attached picture, it seems that you are trying to set an image with a big size. I would like to note that the RadPageViewNavigationViewItems are auto-sized by default. NavigationView switches between different display modes showing only the image or the image and text combined, so stretching the image or setting a maximum size of the item are not acceptable solutions. As a possible solution I would suggest you assign a custom image by setting the appropriate size to the image itself:

RadPageViewNavigationViewElement element = this.radPageView1.ViewElement as RadPageViewNavigationViewElement;
foreach (RadPageViewNavigationViewItem tab in element.Items)
{
    tab.Image = new Bitmap(myImage, new Size(100, 50)); 
}

As to the ItemFillMode property that you mentioned in the previous post defines possible modes to fit items within a RadPageViewStripElement and is applicable when RadPageView is in PageViewMode.Strip. This is why this property is not relevant to your scenario that uses NavigationView.

I hope this helps. Should you have further questions do not hesitate to ask.

Regards,
Nadya
