Introduction

ImageComboBox is an extension of the standard windows combobox control. It supports displaying icons or images in content items. If you look at the windows interface, you will see the windows browser, Internet browser, file open, keep, Print dialog box, all use the drop-down box that can display icons at different levels.

The standard Combobox does not support image display. However, in OwnerDrawn mode, it can display icons or images. Of course, there are still some shortcomings: the image can be displayed in the drop-down list, but when you select an item, it is not displayed on the textbox, unless you set the dropdown type to DropDownList. In DropDownList mode, Combobox cannot be edited.
However, I want the image to be displayed in Textbox in three modes. The ImageComboBox provided in this Article can display the images and text you selected in the list box to the Combobox text box in three modes.

In addition, this ImageComboBox supports multi-level division for each item, which helps to group items and display their hierarchies. When DrawMode is set to OwnerDrawVariable, each item can have its own font and text size. Therefore, each item in Combobox has several attributes, which can be specified statically or dynamically. Then, these items are not just simple strings, but special ImageComboBoxItem objects. Therefore, these items are a collection of ImageComboBoxItem objects.
