Hi,
I have two selectManyListboxes on a jsp page I am trying to move items from one selectManyListbox to other.
Here the selectManyListbox values I have are SelectItem[] types
Here I am using actionListener for moving items
Please anybody could explain me how to do this
any help is appreciated
JSF<h:form>
<h:selectManyListbox value="#{myBean.selectedItemsLeft}">
<f:selectItems value="#{myBean.selectItemsLeft}" />
</h:selectManyListbox>
<h:commandButton value="left to right" action="#{myBean.leftToRight}" />
<h:commandButton value="right to left" action="#{myBean.rightToLeft}" />
<h:selectManyListbox value="#{myBean.selectedItemsRight}">
<f:selectItems value="#{myBean.selectItemsRight}" />
</h:selectManyListbox>
</h:form>
MyBean (this one is a session scoped design)public class MyBean {
private List selectItemsLeft = new ArrayList();
private List selectedItemsLeft;
private List selectItemsRight = new ArrayList();
private List selectedItemsRight;
// + getters + setters
public MyBean() {
loadSelectItemsLeft();
}
public void leftToRight() {
if (selectedItemsLeft != null) {
for (Iterator iter = selectItemsLeft.iterator(); iter.hasNext();) {
SelectItem selectItem = (SelectItem) iter.next();
if (selectedItemsLeft.contains(selectItem.getValue())) {
selectItemsRight.add(selectItem);
iter.remove();
}
}
selectedItemsLeft.clear();
}
}
public void rightToLeft() {
if (selectedItemsRight != null) {
for (Iterator iter = selectItemsRight.iterator(); iter.hasNext();) {
SelectItem selectItem = (SelectItem) iter.next();
if (selectedItemsRight.contains(selectItem.getValue())) {
selectItemsLeft.add(selectItem);
iter.remove();
}
}
selectedItemsRight.clear();
}
}
private void loadSelectItemsLeft() {
selectItemsLeft.add(new SelectItem("key1", "value1"));
selectItemsLeft.add(new SelectItem("key2", "value2"));
selectItemsLeft.add(new SelectItem("key3", "value3"));
selectItemsLeft.add(new SelectItem("key4", "value4"));
selectItemsLeft.add(new SelectItem("key5", "value5"));
}
}
Thanks BaluC sir,
But here my problem is I passing SelectItem[] type values to SelectManyListbox.
here is the code
Here is my bean class
public void setSelectedPriceList(SelectItem[] availablePriceLists)
{
this.selectedPriceList = availablePriceLists;
}
public SelectItem[] getSelectedPriceList()
{
selectedPriceList = getCpgPriceListDtos();
return selectedPriceList;
}
public void setAvailablePriceList(SelectItem[] availablePriceList)
{
this.availablePriceList = availablePriceList;
}
public SelectItem[] getAvailablePriceList()
{
availablePriceList = availablePriceListDtos();
return availablePriceList;
}
Here is my jsp page
<t:panelGrid columns="3" cellspacing="0" border="1" width="75%">
<t:outputText value="Available Price List"/>
<f:verbatim> </f:verbatim>
<t:outputText value="Selected Price List"/>
<t:selectManyListbox style="width: 300px;">
<f:selectItems value="#{mybean.availablePriceList}"/>
</t:selectManyListbox>
<t:panelGrid columns="1">
<t:commandButton value=">" actionListener="mybean.moveToSelected" style="width: 50px;"/>
<t:commandButton value="<<" actionListener="mybean.moveToAvailable" style="width: 50px;"/>
</t:panelGrid>
<t:selectManyListbox style="width: 300px;">
<f:selectItems id="visibleItems"
value="#{mybean.selectedPriceList}"/>
</t:selectManyListbox>
</t:panelGrid
>
Please help me to solve this
thanks in advance
any help on how to get the length of SelectManyListbox and remove the selected values and move that to another selectManyListbox
here my selectManyListbox values are SelectItem[] values so I can't
directly add and remove values
can anybody help me how to do this
any help is appreciated
I already have explained how you could do it. Getting the length, moving the items and converting between an ordinary array and a collection is just basic Java API knowledge.
By the way, if you're using Tomahawk components for the UIInput, then please also use the appropriate t:selectItems component insead of f:selectItems.
