ImageButton2
RedCorners.Forms.ImageButton2 is an alternative to Xamarin.Forms ImageButton, which provides a button that contains an Image and/or a Label. ImageButton2 does not derive from Xamarin.Forms.ImageButton, but instead from Grid.
ImageButton2 comes in four different styles (ImageButtonStyles):
Image(1),Text(2),ImageText(1 | 2),ImageTextStack(1 | 2 | 4)
When ImageText or ImageTextStack styles are used, both an image and a label are shown. In ImageText, the image and label are arranged in a Grid with two different rows, and in ImageTextStack they are arranged in a Grid with four rows, with first and last row heights set to Star values, and the middle two containing the image and the label.
These two different styles visually control how the image and label are aligned next to each other. In ImageText the label takes up as much space as it needs (or the amount set in TextHeight), and the rest of the space is occupied by the image. In ImageTextStack, The image also uses the space it needs, and the remaining space is used as the top and bottom paddings of the control, to vertically center the contents.
The size and margins around the Image component can be assigned via the ImageWidthRequest, ImageHeightRequest and ImageMargin bindable properties.
The label can be customized via the following bindable properties:
TextTextColorFontSizeFontFamilyFontAttributesTextHeightVerticalTextAlignmentHorizontalTextAlignment
Furthermore, through the Orientation bindable property of ImageButton2, four different rotations can be assigned to it:
Up(0),Down(180),Right(-90),Left(90)
Similar to Image and Button controls, the image source can be assigned to the Source property, and the command and its parameter to the Command and CommandParameter properties. However, ImageButton2 also provides the following additional commands:
PressedCommand/PressedCommandParameter: Executed when a touch down event occurs on the control.ReleasedCommand/ReleasedCommandParameter: Executed when a touch release event occurs on the control.
These events come from the embedded Button2 control inside ImageButton2. For more information, refer to Button2.
