    Icon Set
    In This Topic

    The Icon Set data visualization allows you to use arguments to select an image from an image strip and display it either as a BackgroundImage, or as a Value. You can use the standard image strips included with ActiveReports, or create custom image strips.

    The Icon Set Data Visualizer is supported in the Image report control Value property, and also in the TextBox, CheckBox, Shape, and Container report controls' BackgroundImage - Value property.

    Standard Image Strips

    Name Image
    Checkbox Checkbox image
    3TrafficLights 3TrafficLights image
    Arrows Arrows image
    Blank Blank image
    Flags Flags image
    GrayArrows GrayArrows image
    Quarters Quarters image
    Ratings Ratings image
    RedToBlack RedToBlack image
    Signs Signs image
    Symbols1 Symbols1 image
    Symbols2 Symbols2 image
    TrafficLights TrafficLights image

    Note: When using icon sets, you must set the Source property to Database.

    Parameters

    You can use static values or any expression that evaluates to a Boolean value. For icon sets with fewer than five icons, set the unused values to False.

    Syntax

    =IconSet("Flags", False, True, False, False, False)

    Usage

    Following the Icon Set argument, there are five Boolean arguments. The first argument to evaluate to True displays the corresponding image. Use data expressions that evaluate to a Boolean value to replace the literal values in the code above.

    Example

    This expression displays the first symbol (the green flag) on each row in which the Difference exceeds 10, displays the second symbol (the yellow flag) on each row in which the quantity is greater than 0, and displays the third symbol (the red flag) on each row in which the quantity is equal to or below 0. Notice that we provide literal False values in the fourth and fifth arguments, which have no images in this strip.

    Paste in the BackgroundImage Value property of a Textbox
    Copy Code
    =IconSet("Flags",Fields!Difference.Value > 10,Fields!Difference.Value > 0,Fields!Difference.Value <= 0,False,False)
    
    Icon Set Example

    In several of the included image strips, the last spots are empty. When using the Checkbox, 3TrafficLights, Flags, RedToBlack, Signs, Symbols1, Symbols2, or TrafficLights image strip, it generally makes sense to set the Boolean values for all of the unused icon spaces to False.

    Custom Image Strips

    The Blank image strip is included so that you can customize it. Drop down the section below for details.

    Custom image strips

    Custom image strips must conform to the following rules.

    1. The format must be of a type that is handled by the .NET framework.
    2. The size of the strip must be 120 x 24 pixels.
    3. Each image must be 24 x 24 pixels in size.
    4. There must be no more than five images in the strip.
    5. If there are fewer than five images in the strip, there must be blank spaces in the image to fill in.

    Types of Custom Images

    Here is the syntax for various types of custom images, followed by examples of each.

    External image syntax

    =IconSet(location of image strip, condition#1, condition#2, condition#3, condition#4, condition#5)
    External image path example
    Copy Code
    =IconSet("C:\Images\customstrip.bmp", 4 > 9, 5 > 9, 10 > 9, False, False)
    
    External image URL example
    Copy Code
    =IconSet("http://mysite.com/images/customstrip.gif", 4 > 9, 5 > 9, 10 > 9, False, False)
    

    Image from an assembly resource syntax

    =IconSet("res:[Assembly Name]/Resource name", condition#1, condition#2, condition#3, condition#4, condition#5)
    Assembly resource image example
    Copy Code
    =IconSet("res:ReportAssembly, Version=1.1.1.1./ReportAssembly.Resources.Images.CustomImage.png",
    4 > 9, 5 > 9, 10 > 9, False, False)
    

    Embedded image syntax

    =IconSet("embeddedImage:ImageName", condition#1, condition#2, condition#3, condition#4, condition#5)
    Embedded image example
    Copy Code
    =IconSet("embeddedImage:Grades", Fields!Score.Value >=90, Fields!Score.Value >=80, Fields!Score.Value >=70, Fields!Score.Value >=60, True)
    

    Theme image syntax

    =IconSet("theme:ThemeImageName", condition#1, condition#2, condition#3, condition#4, condition#5)
    Theme image example
    Copy Code
    =IconSet("theme:Grades", Fields!Score.Value >=90, Fields!Score.Value >=80, Fields!Score.Value >=70,
    Fields!Score.Value >=60, True)
    

    Data Visualizers Dialog

    To open the dialog, drop down the BackgroundImage property of TextBox, CheckBox, Shape, and Container report controls, or the Value property of Image report control, and select <Data Visualizer...>.  To build the data visualizer expression, select the appropriate values for each of the options in the dialog.
