NLog control to an existing RichTextBox Windows Form

Question

Below is my NLog configuration, I want to load log into existing RichTextBox called rtMessage in Form1, but NLog will create a new windows with log message loaded into the R

Answer 1

1.normally init logger in winform1_Load while it have done InitializeComponent -> has init your own RichTextBox.

2.then makesure your RichTextBoxTarget's FormName and ControlName initialized ok. such as:

RichTextBoxTarget rtbTarget = new RichTextBoxTarget();
logConfig.AddTarget("richTextBox", rtbTarget);
rtbTarget.FormName = "frmScrapeAmazonProduct"; // your winform class name
rtbTarget.ControlName = "rtbLog"; // your RichTextBox control/variable name
