Hi,
I am trying to add a column of checkboxes in data table with CheckGroup
Selector.
Html looks like this
<wicket:panel>
<form wicket:id="form">
<input type="checkbox"
wicket:id="groupselector">check/uncheck
all</input>
<table border="1" wicket:id="entries">[Data Table will be
added
here!!]</table>
<wicket:fragment wicket:id="checkBoxFrag">
<input type="checkbox" wicket:id="selected"/>
</wicket:fragment>
</form>
</wicket:panel>
The Column is added like this
IColumn[] columns = {
new AbstractColumn(new Model("Select - All")){
public void populateItem(Item cellItem, String componentId,
IModel rowModel) {
PhoneBookEntry entry =
(PhoneBookEntry)rowModel.getObject();
cellItem.add(new
PhoneBookEntrySelectionFragment(componentId,
"checkBoxFrag",
PhoneBookPanel.this,
entry));
}
},
new PropertyColumn(new Model("ID"), "id"),
new PropertyColumn(new Model("First Name"), "firstName"),
new PropertyColumn(new Model("Last Name"), "lName", "lastName"),
new PropertyColumn(new Model("Tel No"), "telNum", "telNo") };
DefaultDataTable dataTable = new DefaultDataTable("entries", columns,
provider, 4);
Form form = new Form("form");
MyCheckGroup group = new MyCheckGroup("checkGroup",new ArrayList());
group.add(new CheckGroupSelector("groupselector"));
group.add(dataTable);
form.add(group);
add(form);
The Fragment which generates the Check boxes on each row look like this
public class PhoneBookEntrySelectionFragment extends Fragment {
public PhoneBookEntrySelectionFragment(String id,
String markupId,
MarkupContainer markupProvider,
PhoneBookEntry entry) {
super(id, markupId, markupProvider);
add(new Check("selected", new
CheckBoxModel(entry.getId())) {
protected boolean
wantOnSelectionChangedNotifications() {
return true;
}
});
}
}
The Problem is:
1. If I click on any checkbox on any row all the checkboxes get selected at
once. I noiced that the wicked id if all the checkboxes is the same which in
this case is "selected" . What am I doing wrong here?
2. Also if I replace the follwing line
DefaultDataTable dataTable = new DefaultDataTable("entries", columns,
provider, 4);
with
AjaxFallBackDefaultDataTable dataTable = new AjaxFallBackDefaultDataTable
("entries", columns,
provider, 4);
then the navigation links stop working? Can anyone point out why?
3. Also, I want to be able to disable a button if more than one checkbox is
selected. How can I do that?
Thanks,
Rachit
