Dong Trien Lam — Thu, 23 Feb 2017 02:09:09 GMT

Drag and drop RichTextBox into form in the Form_Load and his running assign content for events RichTextBox_TextChanged RichTextBox but not running although I have to add this line of code:

this.RichTextBox.TextChanged + = new System.EventHandler (this.RichTextBox_TextChanged);

before Form_Load

[CODE]

public Form1()

{

InitializeComponent();

this.RichTextBox.TextChanged + = new System.EventHandler (this.RichTextBox_TextChanged);

this.Load += new System.EventHandler(this.Form1_Load);

}

private void RichTextBox_TextChanged (object sender, System.EventArgs e)

{

do something ...

}

[/ CODE]

as an example of his small examples on running normally, but in the main program will not run, I do not know what is not right ? What advice can you help me fix this.

Did you try adding your event handler through the property sheet? Select the RichTextBox, click the lightning bolt icon in the property sheet and double-click TextChanged. This will add the event handler inside the InitializeComponent() method which is called before anything else.
