In previous posts, I showed you how to create a report using Visual Studio 2010 and how to add a hyperlink to the report.
In this post, I show you how to add an expression based image to each row of the report. This is similar to displaying a checkbox column for Boolean values. A sample project is attached to the bottom of this post.
To start off, download the project we created earlier from here. The report we created had a “Discontinued” column of type Boolean. We are going to change it to display an “available” icon or “unavailable” icon based on the “Discontinued” row value.
Load the project and double click on Products.rdlc. With the report design surface active, you will see the “Report Data” tool window. Right click on the Images folder and select “Add Image..”
Add the available_icon.png and discontinued_icon.png images (the sample project at the end of this post has the icon png files)
You can see the images we added in the “Report Data” tool window.
Drag and drop the available_icon into the “Discontinued” column row (not the header)
We get a dialog box which allows us to set the image properties.
We will add an expression that specifies the image to display based the “Discontinued” value from the Product table. Click on the expression (fx) button.
Add the following expression :
= IIf(Fields!Discontinued.Value = True, “discontinued_icon”, “available_icon”)
Save and exit all dialog boxes.
In the report design surface, resize the column header and change the text from “Discontinued” to “In Production”.
Change Display to “Original size”
(Optional) Right click on the image cell (not header) , go to “Image Properties..” and offset it by 5pt from the left.
(Optional) Change the border color since it is not set by default for image columns.
We are done adding our image column!
Compile the application and run it. You will see that the “In Production” column has red ‘x’ icons for discontinued products.
