I have a form with about 10 data fields and a search button. The search button is the default button when the Enter key is pressed. Only 3 fields are enabled and searchable.

Is there an efficient way to determine which text field had focus when the enter key was pressed (or the search button was clicked)? The search parameters I define will depend upon which field had data entered.

I've been toying with an OnTextChanged action that sets a FieldID value. That works, but the action is called for each keystroke. Again, looking for a better way.

Thanks,

Glenn

You can use the "OnGotFocus" method.

Code:
$Form = $System.Form()
$Form.BackColor = 232,232,232
$Form.Height = 297
$Form.Text = "KiXforms Designer Template"
$TextBox1 = $Form.Controls.TextBox()
$TextBox1.Height = 20
$TextBox1.Left = 15
$TextBox1.Text = "TextBox1"
$TextBox1.Top = 15
$TextBox1.Width = 100
$TextBox1.OnGotFocus = "$Focus = 'TextBox1'"
$TextBox2 = $Form.Controls.TextBox()
$TextBox2.Height = 20
$TextBox2.Left = 15
$TextBox2.Text = "TextBox2"
$TextBox2.Top = 45
$TextBox2.Width = 100
$TextBox2.OnGotFocus = "$Focus = 'TextBox2'"
$TextBox3 = $Form.Controls.TextBox()
$TextBox3.Height = 20
$TextBox3.Left = 15
$TextBox3.Text = "TextBox3"
$TextBox3.Top = 75
$TextBox3.Width = 100
$TextBox3.OnGotFocus = "$Focus = 'TextBox3'"
$TextBox4 = $Form.Controls.TextBox()
$TextBox4.Height = 20
$TextBox4.Left = 15
$TextBox4.Text = "TextBox4"
$TextBox4.Top = 105
$TextBox4.Width = 100
$TextBox4.OnGotFocus = "$Focus = 'TextBox4'"
$Button1 = $Form.Controls.Button()
$Button1.Height = 23
$Button1.Left = 15
$Button1.Text = "Button1"
$Button1.Top = 135
$Button1.Width = 75
$Button1.OnClick = "$Focus"


That's in kf classic, I'm not sure if kf.net has a different mechanism or not, though.

OK - thanks.. that's similar to what I'm doing. My searchable field definitions look like this:
Code:
  $txtEMPNO      = $tabPAGE0.TextBox()
  $txtEMPNO.Top    = $Row + 15
  $txtEMPNO.Left   = $Col
  $txtEMPNO.Width   = $InpWidth
  $txtEMPNO.Height   = $InpHeight
  $txtEMPNO.MultiLine   = 0
  $txtEMPNO.FontName   = $InpFontN
  $txtEMPNO.FontSize   = $InpFontS
  $txtEMPNO.OnTextChanged= '$MODIFIED=1'
  $txtEMPNO.OnGotFocus= '$ACTIVEFIELD=2'
All fields set the modified flag, but only searchable fields set the ACTIVEFIELD flag, and identify not so much which field but what type of search parameter to set.

Loading data from the database clears the MODIFIED flag, so if a user clears the form or exits I can prompt them to save. Loading also sets a LOADED flag, which prevents triggering the search function if a user presses ENTER on a searchable field during entry or edit. If no data is found, the LOADED flag is set to prevent further searches and the system goes into Entry mode instead of Edit mode.
