Hi All,
I'm trying to add select All Checkbox to the header of wicket DataTable
column, I've read that I need to use CheckGroup and CheckGroupSelector. I'm
doing the following:
Form form = new Form("form");
CheckGroup group = new CheckGroup("group");
group.add(new CheckGroupSelector("groupselector"));
DataTable sourceTable = new DataTable("mytable", getColumns(),
getDataProvider(), 10);
sourceTable.setOutputMarkupPlaceholderTag(true);
group.add(sourceTable);
add(form);
form.add(group);
private List getColumns() {
List<IColumn<MyItem, String>> ret = Lists.newArrayList();
ret.add(new AbstractColumn<MyItem, String>(new Model<>("")) {
@Override
public void populateItem(Item<ICellPopulator<MyItem>>
cellItem, String componentId, IModel<MyItem> rowModel) {
CheckBoxPanel checkBoxPanel = new
CheckBoxPanel(componentId);
cellItem.add(checkBoxPanel);
}
});
...
}
<input type="checkbox" wicket:id="groupselector">check/uncheck all</input>
[Lookup Results]
To add CheckBox to the DataTable I must use a Panel, so I have the
following:
public class CheckBoxPanel extends Panel {
private CheckBox field;
public CheckBoxPanel(String id, IModel<Boolean> model) {
super(id);
field = new CheckBox("checkBox", model);
add(field);
}
public CheckBoxPanel(String id) {
this(id, new Model<Boolean>());
}
public CheckBox getField() {
return field;
}
}
In CheckBoxPanel.html
<body>
<wicket:panel xmlns:wicket="http://wicket.apache.org";>
<input type="checkbox" wicket:id="checkBox">
</wicket:panel>
</body>
Actually it does show checkgroup but under my table and checking/un-checking
it does not affect the check boxes under it. What am I doing wrong here?
