Color specific cells in a Tablix Textbox RDLC Report based on Condition - Vb.net - RDLC

Question

I have made a RDLC report which generates its tablix from the dataset I provided. I need the content of cell(each Textbox in Tablix) to change its backColor based on its content.

Eg:

Name | Val  
Joe  | 80  
Lee  | 60  
Fred | 30  
Bill | 57  

I have a condition that less than 60 should change its backcolor to red. (so, 30 and 57 will be getting its backcolor as red).

Note: Since it loads from dataset, you cannot set it directly. Is there any way if we pass conditions as parameters to rdlc and work on its own??

Answer 1

Use an expression in the background property. You can get the current value of some field that you've read in using: Fields.Name_Of_Field.Value, it will automatically move to the correct one on each row.

if you have single test you can use this

=IIF(Fields.Val.Value < 60, "Red", "Blue")

if you have multiple test you can use this

=SWITCH(
 Fields.Val.Value < 60, "Red",
 Fields.Val.Value < 80 && Fields.Val.Value >= 60, "Blue",
         .
         . add other tests here
         .
 "Black") ' default is black in case all the tests fail

One of the great things about RDL is the number places you can use expressions. Try this for a starter
