Conditionals in ASP.NET can be written in a concise manner using an

I am looking to create a custom statement similar to the following:

<%#((bool)Eval("inactive")) ? "<span style='color:red;font-weight:600;'>INACTIVE</span>" : "<span style='color:green;font-weight:600;'>ACTIVE</span>"%>

However, I need this statement to be able to handle 3 conditional statements.

So instead of using

<%#Eval("Program_Num") %>

I want it to output as follows:

  • If Program_Num equals 1, then display X
  • If Program_Num equals 2, then show Y
  • If Program_Num equals 3, then display Z

I am willing to provide further clarification if needed. Thank you for your assistance.

Answer №1

Consider attempting something along these lines.

<%# (int)Eval("Program_Num") == 1 ? "X" : (int)Eval("Program_Num") == 2 ? "Y" : (int)Eval("Program_Num") == 3 ? "Z" : "default value" %>

This can be compared to the following explanation.

if ((int)Eval("Program_Num") == 1)
    "X"
else if ((int)Eval("Program_Num") == 2)
    "Y"
else if ((int)Eval("Program_Num") == 3)
    "Z"
else
    "default value"

Answer №2

Consider attempting the code snippet below:

<%#Eval("Program_Num") == 1 ? "A" : Eval("Program_Num") == 2 ? "B" : Eval("Program_Num") == 3 ? "C" %>

Remember to replace "A" "B" "C" with your desired values for display.

Answer №3

While this method may not be the most elegant solution, you can achieve your desired outcome by incorporating a nested version of it:

let x = Program_Num === 1 ? "X" : (Program_Num === 2 ? "x" : (Program_Num === 3 ? "y" : "DEFAULT"))

This example is written in clean JavaScript syntax for better understanding, but feel free to modify it for use in an ASP.NET environment.

If you find yourself nesting statements for multiple levels, it may be beneficial to consider utilizing proper if or switch constructs for improved readability and maintainability.
