Hi Praveen,

You could add the items to the drop down list in a sorted order, which would involve loading the items into an array, sorting them and then loading them into the drop down list.  So this would be in the click event of the add button.

// Create an array to hold all out drop down list items, the array contains objects with a "displayItem" and "value" property

var dropDownItems = [];

// Add the new one

dropDownItems.push({displayItem: ItemName.rawValue, value: BoundValue.rawValue});

// Add the existing ones

for (var i = 0; i < DropDownList1.length; i++)

{

    dropDownItems.push({displayItem: DropDownList1.getDisplayItem(i), value: DropDownList1.getSaveItem(i)})

}

// Sort ascending order of the display text

dropDownItems.sort(

    function(a, b)

    {

        if (a.displayItem < b.displayItem) return -1;

        if (a.displayItem > b.displayItem) return 1;

        return 0;

    });

// clear all items

DropDownList1.clearItems();

// load up the sorted items

for (var i = 0; i < dropDownItems.length; i++)

{

    var dropDownItem = dropDownItems[i];

    DropDownList1.addItem(dropDownItem.displayItem, dropDownItem.value);

}

// clear source fields

ItemName.rawValue = null;

BoundValue.rawValue = null;

I've added a "Add Sorted" button to my sample, https://workspaces.acrobat.com/?d=OwysfJa-Q3HhPtFlgRb62g

Hi,

You can use the addItems and if your users have Reader 8.0 or later you can use deleteItem (otherwise you have to clear them all then add back all but the deleted one).

Here is a sample  https://workspaces.acrobat.com/?d=OwysfJa-Q3HhPtFlgRb62g

Another option:

I have two text fields named Party1 and Party2.  When a name is entered in the text field(s) it then becomes available in the drop list.

I used the javascript below on the *pre-open event.

this.rawValue = null;

this.clearItems();

this.addItem(Party1.rawValue);

this.addItem(Party2.rawValue);

Hi Bruce,

I have struck with a problem again, your example

https://workspaces.acrobat.com/?d=OwysfJa-Q3HhPtFlgRb62g

works great..

But my dropdown box is within a table which has repeating rows ...

So i want to invoke instance manager for the code to work ..But its not

happening..

Can you please provide the solution with your above example modified....for

repeating rows

Regards,

Praveen

Hi Praveen,

Will the drop down list in all the rows have the same value or will you be adding/removing from the one in the the 'current' row.

If the drop down list in all the rows have the same value then I would probably bind them to a common data set.

All the Dropdown Boxes in all the rows should  have same items what we add,

But selections in Dropdown Box may vary based on the selection...check the screenshot and do the needful...

All the dropdown boxes should contain Items that we add...

Hi Praveen,

Your form is not shared so I have not been able to access it.  But I have updated mine.  There are now two approaches, one that follows on from the above method and updates each drop down list in each row.  The second updates a separate dataset that the drop down list is bound to.  This second approach requires the remerge() method which can cause problems if your code has updates some form properties like a borders color as these will be reset, but the code is simplier and you will only have one list to maintain.  The add button click code is;

var particulars = xfa.datasets.resolveNode("particulars");

if (particulars === null)

{

    particulars = xfa.datasets.createNode("dataGroup","particulars");

    xfa.datasets.nodes.append(particulars);    

}

var particular = xfa.datasets.createNode("dataValue","particular");

particular.value = ItemName.rawValue;

var boundValue = xfa.datasets.createNode("dataValue","id");

boundValue.value = BoundValue.rawValue;

particular.nodes.append(boundValue);

boundValue.contains = "metaData";

// find sorted position to insert

for (var i = 0; i < particulars.nodes.length; i++)

{

    p = particulars.nodes.item(i);

    if (p.value > particular.value)

  {

      particulars.nodes.insert(particular, p);       

             break;

  }

}

// add to end if greater than all existing items

if (particular.parent === null)

{

    particulars.nodes.append(particular);

}

// clear source fields

ItemName.rawValue = null;

BoundValue.rawValue = null;

// remerge form data to pick up new item

xfa.form.remerge();

And the binding looks like;

I have updated my sample to include both methods, https://workspaces.acrobat.com/?d=OwysfJa-Q3HhPtFlgRb62g

Hi Praveen,

I have updated you sample, https://workspaces.acrobat.com/?d=1jB1CsAXZ7g6QiRQLPCjEw.

I have removed the four values you had in the dropdown list DataDropDownList00 and placed them in a dataset so the drop down list can bind to them, you will need to use the XML Source view if you need to update or add to them. 

Good luck

Hi Praveen,

The remove button works for me, enter the Item Name click remove and it is removed, how did you want it to work.

Also, what was the clear button to do, remove the ones added leaving the four initial values or remove the lot.  Either way this is a trival variation on the remove code.
