AW: How would you realize a delete-Link in a datagrid row?
In addition: my specific problem is, that after clicking on a link which is generated in the datagrid, I am not able to manipulate other components!?

AW: How would you realize a delete-Link in a datagrid row?
Hi Ernesto, I don't get it: How can I change the Label-Text? When I try to change the Model of the component Label, nothing happens. The page reloads and the Label has the old Text (not the new one which is meant to be changed) - Ursprüngliche Mail Von: Ernesto Reinaldo Barreiro reier...@gmail.com An: users@wicket.apache.org Gesendet: Mittwoch, den 30. September 2009, 11:38:33 Uhr Betreff: Re: How would you realize a delete-Link in a datagrid row? What about replacing the link. e.g. via AJAX, with a new one containing the Do you really want to delete xyz warning... that once clicked actually deletes your entry... and refreshes the datagrid. You could even use the same link and have a flag that says userWantsToDeleteRow and use it to conditionally change the actions to do and the contents to display.

Thank you! Your solution is really nice.
It functions well!
I have a problem which the datagrid. After removing a row in the database it
throws an exception, because wicket is unable to populate an item (I assume the
deleted one)
How can I tell wicket to reload the datagrid because something in the DB
changed.

I created a deteletButton as follows. I have a DeleteButton innerclass, and a
method that adds this button to the panel that is shown in the table.
private class DeleteButton extends Button {
private static final long serialVersionUID = 1L;
public DeleteButton(final String id, final IModelString model) {
super(id, model);
}
@Override
public void onSubmit() {
try {
deleteData((String) getModelObject()); // a method that does the
actual data deletion in the database
} catch (SQLException se) {
error(StringResources.SQLERROR_GET + '\n' + se.getMessage());
} catch (IOException ie) {
error(StringResources.IOERROR + '\n' + ie.getMessage());
}
}
@Override
public boolean isEnabled() {
return isEditingAuthorised();
}
}
private void addDeleteLink(final IModel? model) {
String id = (String)getIdFromModel(model); // a method that extracts
the id from the model (based on what kind of class is in the model)
Button deleteButton = new DeleteButton(delete, new
ModelString(id));
deleteButton.add(new Image(deleteIcon, new
ResourceReference(EmptyIconReference.class, list-remove.png)));
deleteButton.add(new SimpleAttributeModifier(onclick, return
confirm('Are you sure?');));
add(deleteButton);
}
I hope this helps.

Re: AW: AW: How would you realize a delete-Link in a datagrid row?
table = new AjaxFallbackDefaultDataTable(datatable, createColumns(),
contentProvider, 10);
@Override
protected IColumn?[] createColumns() {
IColumn?[] columns = new IColumn[3];
columns[0] = createActionsColumn();
columns[1] = new PropertyColumnString(new
ResourceModel(label.name), name, name);
columns[2] = new PropertyColumnString(new
ResourceModel(label.owners), owners, owners);
return columns;
}
So datatable would become benutzer, contentProvider would become new
AdministratorDataProvider(), and you'd have to add your own columns.
(The number 10 is the number of rows you want to show on a page.)
On the Wicket-examples site is an extensive example of this construct.

Re: AW: How would you realize a delete-Link in a datagrid row?
Wrap the dataview in a WebMarkupContainer .
1) Create a WebMarkupContainer
2) Create your data view
3) Add the dataview into the wmc
4) Don't forget to set .setOutputMarkupId(true); on the dataview
5) On the return of the Modal window refresh the target I.E.
target.addComponent(wmcDataTable);
Or this example will work with an ajax link instead of a modal window.
final WebMarkupContainer wmcDataTable = new
WebMarkupContainer(wmcDataTable);
wmcDataTable.setOutputMarkupId(true);
final DataViewUsers eachUser = new DataViewUsers(eachUser, dp) {
protected void populateItem(final ItemUsers item) {
final Users user = (Users)
item.getModelObject();
item.setModel(new
CompoundPropertyModelUsers(user));
item.add(new AjaxLinkUsers(deleteLink, item.getModel()) {
public void onClick(AjaxRequestTarget
target) {
modalUsersDelete.setContent(new
VendorProfileUsersDeletePanel(modalUsersDelete.getContentId(),
(Users)
item.getDefaultModelObject()));
modalUsersDelete.show(target);
}
});
// add items
});
eachUser.setItemsPerPage(ROWS_TO_DISPLAY);
eachUser.setOutputMarkupId(true);
wmcDataTable.add(eachUser);
form.add(wmcDataTable);
modalUsersDelete = new ModalWindow(modalUsersDelete);
modalUsersDelete.setInitialWidth(450);
modalUsersDelete.setInitialHeight(230);
modalUsersDelete.setOutputMarkupId(true);
modalUsersDelete.setTitle(Delete User);
modalUsersDelete.setWindowClosedCallback(new
ModalWindow.WindowClosedCallback() {
public void onClose(AjaxRequestTarget target) {
target.addComponent(wmcDataTable);
