Hi,

 

getSelectedIds only works on a view panel, not in a repeat control. In a repeat control you can bind a checkboxes to a viewScope variable.

The trick to it is that you first fill the viewScope variable with a blank array with the same number of items than the repeat control. You then bind a checkbox to an indexed item of that array.

 

Copy the following code to a new blank XPage to see a sample:

<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">
   
    <xp:this.afterPageLoad><![CDATA[#{javascript:var numEntries = getComponent("repeat1").getRowCount();
viewScope.put("selectedIds", new Array(numEntries) );}]]></xp:this.afterPageLoad>
    <xp:repeat id="repeat1" rows="30" var="dataItem"
        indexVar="dataIndex">
        <xp:this.value><![CDATA[#{javascript:[
 {name: "item 1", id: "id1"},
 {name: "item 2", id: "id2"},
 {name: "item 3", id: "id3"},
 {name: "item 4", id: "id4"}
]}]]></xp:this.value>
        <xp:checkBox id="checkBox1"
            checkedValue="#{javascript:dataItem.id}" uncheckedValue="">
            <xp:this.value><![CDATA[#{viewScope.selectedIds[dataIndex]}]]></xp:this.value>
        </xp:checkBox>
        <xp:text escape="true" id="cfName"
            value="#{javascript:dataItem.name}">
        </xp:text>
        <xp:br></xp:br>
    </xp:repeat>
    <xp:br></xp:br>
    <xp:button value="Show selected" id="button1">
        <xp:eventHandler event="onclick" submit="true"
            refreshMode="partial" refreshId="cfSelectedIds">
        </xp:eventHandler></xp:button>
    <xp:br></xp:br>
    <xp:br></xp:br>You've selected:&#160;
    <xp:text escape="true" id="cfSelectedIds"
        value="#{javascript:@Trim(viewScope.selectedIds)}">
    </xp:text></xp:view>

 

 

Mark,

 

In the example I did I used java.util.ListArray I think.  So there no need to know the total count of the repeat control.  It's more like a list where you can just add as needed. 

Not sure which way is better - just wanted to mention it to you.

Dave,

 

I had at look at the demo you created: your and my alternative both eventually do the same. They offer a way to store/retrieve a list of selected rows (when not using a view control) in a server variable.

The main difference is that in your demo a server-call is made on every click of the "Add" button. In that call an ID of the clicked row is added to the a viewScope (array) variable.

In my sample I've bound the checkboxes directly to a viewScope variable (that's why I have to create an array containing a specified number of items before the page is rendered). This doesn't require a server-call for every checkbox tick/ untick: it send the selected items to the server when the "Show selected" button is clicked. For an end user this works/ looks the same as offering default checkboxes in a viewPanel.

 

Cheers,
Mark

 

 

Interesting.  Thanks for pointing out the difference to me.  I knew I was generating server calls on each button.  I didn't realize yours was more done as a batch.

 

thanks!

Mark

 

I have used your method to get checkboxes in a repeat and it works great.  Do you know how you would go about adding a 'Select All' checkbox that ticked all the checkboxes?

Ed,

 

You could do that in a number of ways.

If all your entries are on one page, you could add a clientside script to the button that checks all the boxes. Using dojo that could be something like (not tested btw):

 

 

Another approach would be to call a serverside script that fills the selectedIds viewScope variables with all the ID's of the items in the repeat (in the same order !).

Mark

Basically you want to do a getSelectidIDs but with a repeat control and not a view panel right?

 

I've done this.  It's on my short list for a NotesIn9 episode but I've not recorded it yet.  There is an example in the demo app on http://xpagescheatsheet.com

Click on "Picking Rows" on the left.  You can download the the example and pick it apart, or wait for the NotesIn9 show...

 

hope that helps

Dave

David,

 

Checked out your example, exactly what I need. I'll download it and have a go..

 

BTW the support on this site is great... and Xpages seems to answer all my clunkiness issues.. let's hope it takes off..

This example is already old, but may be should help:
