Once you have written your custom control, it is simple to
incorporate it into Kartris. First, upload it to the
/UserControls/Custom/
folder.
Next, create a new single version product.
Give it an appropriate name, but price is not important as that will
come later from the custom control.
Finally, edit
the product and go to the object config tab. Enter the name of the
control in the
K:product.customcontrolname object
config setting. For example: 'SampleCustomControl.ascx' (the .vb part
will be linked in automatically).
When you view
this product on the front end, you should now see your custom control
providing most of the interface.
