C#: Need one of my classes to trigger an event in another class to update a text box
- by Matt
Total n00b to C# and events although I have been programming for a while.
I have a class containing a text box. This class creates an instance of a communication manager class that is receiving frames from the Serial Port. I have this all working fine.
Every time a frame is received and its data extracted, I want a method to run in my class with the text box in order to append this frame data to the text box.
So, without posting all of my code I have my form class...
public partial class Form1 : Form
{
CommManager comm;
public Form1()
{
InitializeComponent();
comm = new CommManager();
}
private void updateTextBox()
{
//get new values and update textbox
}
.
.
.
and I have my CommManager class
class CommManager
{
//here we manage the comms, recieve the data and parse the frame
}
SO... essentially, when I parse that frame, I need the updateTextBox method from the form class to run. I'm guessing this is possible with events but I can't seem to get it to work.
I tried adding an event handler in the form class after creating the instance of CommManager as below...
comm = new CommManager();
comm.framePopulated += new EventHandler(updateTextBox);
...but I must be doing this wrong as the compiler doesn't like it...
Any ideas?!
