You can change the background of an item in the headers by setting its Background property to the desired color. However, you must keep the following in mind:
<b>In some cases, property values defined in a style will not be applied to a target element. </b>
These include, but are not limited to: – The element’s template does not have a binding for the specific property. – The element’s template ignores the property value. – The element’s template explicitly provides a value for the property.
