SSRS Reporting Services | Basic Custom Assemblies exercise | Use a custom assembly function to change colours
This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.
You can learn how to do this exercise on the relevant Wise Owl classroom training course (sadly for the moment only in the UK).
You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
The aim of this exercise (which you can do using either VB or C#) is to change the fill colour of the rows of a table whenever the certificate changes:
Whenever the certificate changes, we swap colour.
To do this, create a report called Blue in parts, and within this create a basic table above. Eventually you'll set the back colour of each row to be an expression similar to:
However, we have to write the BackColour function first! To make a start on this, in your VB class create the following private variables and constants:
'the current certificate, whose name we are monitoring
Private Shared CurrentCertificate As String = ""
'whether to use the first colour or the second
Private Shared IfFirstColour As Boolean = True
'the two colours to use
Private Const FirstColour As String = "#FFEEFF"
Private Const SecondColour As String = "#EEFFEE"
Alternatively, if you're using C#:
// the current certificate, whose name we are monitoring
private static string CurrentCertificate = "";
// whether to use the first colour or the second
private static bool IfFirstColour = true;
// the two colours to use
private const string FirstColour = "#FFEEFF";
private const string SecondColour = "#EEFFEE";
Write a function called BackColour which spits out either the value of FirstColour or SecondColour, given a certificate name.
For each certificate you should compare its name to the one held in the variable CurrentCertificate. If they're not the same, you should reset the value of the IfFirstColour flag, then reset CurrentCertificate to be the latest certificate name ready for the next call to the function.
When (if?) you've got all of this written and built, see if you can get your report working as shown at the start of this exercise!
