Deleting Single or Several Rows 
Since you have already defined the lead selection when you created and bound the table to the context in addition to implementing the option of multiple selection, you now simply need to read this in the next step in order to be able to delete the selected data records.
Procedure

7. Enter DeleteProducts as name and Delete Products as text. Leave the other settings unchanged and choose Finish.
8. Switch to the implementation of the event handler onActionDeleteProduct and insert the following code:
onActionDeleteProduct() |
//@@begin onActionDeleteProduct(ServerEvent) int n = wdContext.nodeProducts().size(); int leadSelected = wdContext.nodeProducts().getLeadSelection(); // loop backwards to avoid index troubles for (int i = n - 1; i >= 0; --i) { if (wdContext.nodeProducts().isMultiSelected(i) || leadSelected == i) { wdContext.nodeProducts().removeElement(wdContext.nodeProducts(). getElementAt(i)); } } //@@end |
To avoid problems with the index, the context is here executed in reverse. All elements selected in the table are deleted.
