Additional Pane Item Controls

One of the most attractive view modes is the thumbnail view mode, as it displays small thumbnails of original images and is more obvious to the user. In this mode, the displayed thumbnails may have additional controls, both interactive and non-interactive.

To non-interactive controls belongs only the quality meter. Using all other controls the user can perform some actions. All these additional controls are described below.

Checkbox

Checkbox
Fig. 1. Checkbox

This control appears only in the two-pane layout mode and does not require any extra set-up, as it appears automatically. Using checkboxes the user can select files for upload.

If the AllowMultipleSelection property is set to false, radiobuttons will be displayed instead of checkboxes.

Large Preview Control

This control appears both on the folder pane and the upload pane, hence, it supports all three layout modes. The control appears in a form of a magnifier when the user hovers the mouse pointer over some thumbnail in the pane. By clicking this magnifier the user opens a separate window where a larger preview of the selected image is displayed.

To add this control to the pane items, set the AllowLargePreview to true. The following additional properties will help you to customize this control:

Rotation Controls

To add this control to the pane items, set the EnableRemoveIcon to true. The following additional properties will help you to customize this control:

As it was mentioned above, this control is non-interactive, that is it only displays some information. It appears both on the folder pane and the upload pane, hence, it supports all three layout modes. It appears as a colored strip divided in sections, where each section corresponds to some predefined format.

To add this control to the pane items, set the QualityMeterFormats property to a list of formats. The strip will show up automatically. There are also a bunch of additional properties that allow appearance customizing of this control. They are:
