Hi

How do I check if the user pressed "Enter" on the keyboard?

Right now I have a textbox with a keyPress event, but I cant seem to figure out how to do as my topic description says..

I think I need to use e.KeyChar, but cant seem to find it out

Thanks

You can test for an Enter Keypress like this:

csharp

if( e.KeyChar == Keys.Enter)
{
   //Enter Pressed
}
else
{
   //Enter not pressed.
}

Operator '==' cannot be applied to operands of type 'char' and 'System.Windows.Forms.Keys'


the KeyPress event uses the char value of the keys. so you will either need to do this:

csharp

if (e.KeyChar == (char)Keys.Enter)
{
        // Enter key pressed
}
else
{
       // some other key pressed
}


or

csharp

if (e.KeyChar == 13)  // 13 is the ASCII value for a carriage return
{
        // Enter key pressed
}
else
{
       // some other key pressed
}
