# ASP Rendering Tab

Use this tab to determine how the field will look when it is compiled into ASP code when viewed in a web browser. The ASP Rendering Code is Visual Basic code that takes in as arguments the session variable for the instance of the Custom Field Type, the field identifier, and the display only indicator. The field identifier is a unique value determined by Genesys Agent Scripting to identify a field and is prepended to any form variables. This is an example of code that might be entered in the ASP Rendering tab.

<%

Function CFTRR_My_New_Type(sess_var, field_identifier, disp_only)

Dim html

'This code should be written in VBScript and should return

'the HTML as a string to render the field.

'Make sure if you prepend field_identifier to any form element names.

'Use code similar to getProp(field_identifier, "prop_name") to get CFT properties.

If disp_only = 1 Then

'Display only, so just print session variable:

html = sess_var

Else

'The next lines of code creates a text box and sets its initial value based on the session variable:

html = "<input name='" & field_identifier & "val1'"

html = html & " size=" & getProp(field_identifier, "size")

html = html & " value='" & sess_var & "'>"

End If

CFTRR_My_New_Type = html

End Function

%>

This function creates an <input> tag containing the name, size, and value attributes.

Properties defined in the Properties tab can be assigned to attributes in a tag in the ASP Rendering code. To do this, the property is referenced by the getProp() function call, as seen by the size attribute and its assigned property above in the example code.
