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

  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

  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.

  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.

  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 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

  I have it on the InitializeComponent() method but still doesn't work. What could be the reason

  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.

  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

  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();

  }

  }
