Checkboxes and a Pie Chart

Question

1.00/5 (1 vote)

See more:

I am currently working on an asp.net page that I want the users to check some checkboxes and as the users check the check boxes I would like a pie chart that would update on a button click. For example..

C#

if (checkbox1.checked = true)
{
 piechart1 = 10%;
}

i'm sure that this is not how this is done but just so you get the idea.

I am pretty new to both charts and asp.net so any help is appreciated. Thanks!

Can I unsee it?! :-)

Suppose you wanted to say if (checkbox1.checked == true) { /* ... */ } and mixed up '==' (check for equality) with '=' (assignment) and lost the upper-case in "Checked" ("checked" would not compile). It happens. But isn't it obvious that if (checkbox1.checked == true) { /* ... */ } should be if (checkbox1.Checked) { /* ... */ }, because CheckBox.Checked is already Boolean; there is no need to compare it the true?

This is not even a bug. This is the indication of what you are doing, programming, or just wasting your time.

It cannot be the idea of anything. Listen to a good advice: stop working with charts or anything, stop ASP.NET development or whatever else you are doing. You can use your time much better. Learn programming, from the very beginning: types and instances, variables and members, operators; do simple exercises, better with simple console-only application. This is what you really need right now. ASP.NET, graphics, UI — it all needs OOP, but you are not even close. Don't rush, because, right now, doing all that, you will stay frustrated, won't go anywhere. Until you learn the very basics.
