'System.EventArgs' is a 'type' but is used like a 'variable'

  Try the KeyPressed Event and it will work fine.

  private void txtusername_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)

  {

  if(e.KeyChar == (char)Keys.Enter)

  {

  Console.Write("a");

  }

  }

  Let me know if this is helpful.

  hi,

  you didn't miss anything simply your removed the useless curly brackets . those brackets for class declaration

  class Form2 : Form

  {

  }

  because you didn't take the form declaration you shouldn't copy those pair of brackets as well

  also when you use if statment you supose to write it like this

  if ( condition is true)

  {

  //block of code here

  }

  but if your block of code is one line you may don't use curly brackets like this

  if(condition is true)

  //one line

  but its a good habit to use them always

  what still remain is that the method pair of curly brackets

  public void keypress(object sender, keypresseventargs e)

  {

  //if statment

  }

  hope this helps

  Here is my revised code but when I press ENTER key, nothings happens, it doesn't move to the next control.

  private void txtusername_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)

  {

  if(e.KeyChar == (char)Keys.Enter)

  {

  this.txtpassword.Focus();

  }

  }

  I know why.Did you subsribe to the KeyPress event

  this.txtusername.KeyPress += new System.Windows.Forms.KeyPressEventHandler(this.txtusername_KeyPress);

  Write this code at the very end of the InitializeComponent method.

  I had created a new form and the code works. I think im missing some thing with my previous form.

  Thanks.

  Thanks for the reply, but how can I get to the txtusername_keypress method I cant see it from the code window, e.g. formname.cs.

  Regards

  Karthik is correct, however I'll just add that your syntax is wrong because you specify EventArgs (which is a type ) as if it was a variable ( although you really specify it as if it was a function and you were calling it, passing e as an argument ).

  if (EventArgs (e) == Keys.Enter)

  As you've been shown, you would access e, and it's properties, you wouldn't specify the type again like this, brackets or no brackets.

  Still doesn't work, this block of code doesn't executed.

  {

  if (e.KeyChar == 13)

  {

  textbox2.focus();

  }

  }

  But if I removed a pair of curly brackets like the code below, it was executed.

  {

  if (e.KeyChar == 13)

  textbox2.focus();

  }

  Why like that whats really wrong with the given solutions Or does my form has problem I'll try another new form..

  hi,

  you can try the key code

  public Form1() { InitializeComponent(); this.textBox1.KeyPress += new System.Windows.Forms.KeyPressEventHandler(this.textBox1_KeyPress); } private void textBox1_KeyPress(object sender, KeyPressEventArgs e) { if (e.KeyChar == 13) { textBox2.Focus(); } }

  hope this helps
