How to refresh the Labels and other controls inside the GroupBox/Panels inside a Form in C#?

I'm designing a C# application where I have a groupbox showing OS and RAM related information. I designed it using the controls - labels put together in a Groupbox showing RAM related information.

I have a Refresh button which when clicking should display % of RAM used currently.

For this, I need the label (and also few other labels) inside the groupbox to refresh and re-compute the value.

How do i do this? I tried all below in the RefreshButton_Click event but nothing works:

label1.Refresh(); 

GroupBox1.Refresh(); 

Form1.Refresh(); 
Form1.Invalidate(true); 

Panel1.Refresh();

Pls help in this as I do not think reloading an entire form would an efficient solution.

Solution

  • Refreshing won't do anything but display the same assigned value. You must set the new calculated values to your controls inside your RefreshButton_Click handler: 

    var myNewValue = CalculateNewValue();
label1.Text = myNewValue;

    Hope it helps!
