Demo - Add and "Delete" Rows from a window
|
||
|
|
|
||
|
|
This is cut-down version of the Fed-Ex package tracking demo
|
||
|
|
|
||
|
|
The purpose is to show a technique for making windows that grow by clicking an "Add Row" button
|
||
|
|
Each row can be individually "deleted".
|
||
|
|
|
||
|
|
The reason for using the quotes are "deleted" is that the elements are simply hidden. The effect is the same as deleting them.
