Label? Which one? Full type name, please. And what's the problem? All Label types allow custom color, background and foreground. What's wrong with reading original MSDN documentation?

Should I change the back color for every label manually. "100 label"

Sergey Alexandrovich Kryukov 11-Aug-15 13:43pm

What does it mean, "manually"? Again, what's the problem?
(You did not answer my question, but I can see that you probably work with System.Windows.Forms.Label. However, who will want to talk with you if you don't answer important questions?)
What have you tried so far?

for example label "A1" ---- RED
"A2" ---- GREEN
"A3" ---- RED

protected void btnUpadte_Click(object sender, EventArgs e)
{

ParkingLot p = new ParkingLot();
int x = p.GetStatusLot("A1");
if (x == 1)
{
lblA1.BackColor = System.Drawing.Color.Red;
}
else if (x == 2)
lblA1.BackColor = System.Drawing.Color.Green;
else if (x == 3)
lblA1.BackColor = System.Drawing.Color.Orange;
}

should I repeat the function for 100 lable?

Sergey Alexandrovich Kryukov 11-Aug-15 13:44pm

Are you serious? The question is different: are you going to programming or something opposite to programming?

what should I do instead to use the label??

Sergey Alexandrovich Kryukov 11-Aug-15 14:00pm

Why "instead"..? You know, the discussion goes nowhere. You don't need an advice, you only need to learn some elementary programming, perhaps even loops, methods and so on, some programming style, and so on...

Solution 1

Try:

C#

foreach (Control c in Controls)
    {
    Label l = c as Label;
    if (l != null)
        {
        l.ForeColor = Color.Red;
        l.BackColor = Color.Green;
        }
    }

You may need to recursively do the same thing for container controls on the main form.

A1.BackColor = GetColor(A1);
A2.BackColor = GetColor(A2);
.....

A100.BACKCOLOR = GetColor(A100);

ParkingLot p = new ParkingLot();
int x = p.GetStatusLot(label1.ID);

How can I reduce the code the first function "btnUpadte_Click"

OriginalGriff 12-Aug-15 5:01am

Just replace the

l.ForeColor = Color.Red;
l.BackColor = Color.Green;

in my code with

l.BackColor - GetColor(l);

Done!
