備註

ImageKey屬性指定影像清單中要在控制項上顯示的影像。The ImageKey property specifies the image from the image list to display on the control.

ImageKey 和 ImageIndex 都是互斥的，也就是說，如果設定了一個，另一個會設定為不正確值並予以忽略。ImageKey and ImageIndex are mutually exclusive, meaning if one is set, the other is set to an invalid value and ignored. 如果您設定 ImageKey 屬性， ImageIndex 屬性會自動設定為-1。If you set the ImageKey property, the ImageIndex property is automatically set to -1. 或者，如果您設定 ImageIndex 屬性，會 ImageKey 自動將設定為空字串 ( "" ) 。Alternatively, if you set the ImageIndex property, the ImageKey is automatically set to an empty string ("").
