Hi cperez1087,

Thank you for posting in the community.

I suggest that you take a look at the following article on the topic of styling and theming the igDatePicker:

https://www.igniteui.com/help

 Regarding changing the dropdown button's image of the date picker, below is some sample code illustrating how a custom styling can be applied to the control's icon. In this case the images are removed and a background color is applied:

[code]

    <style type="text/css">
        .customTheme .ui-icon
        {
            background-image:none;
            background-color:Green;
        }
   
        .customTheme .ui-state-default .ui-icon {
        background-image: none;
        }
   
    </style>

[/code]

Please let me know if this helps.
