Meta tag worked for IE9.

Hi Yudi,

The Parent combo is called wcboTechnique and the Child combo is wcboInstrumentGroup. I add a row to wcboInstrumentGroup onShowDropDown event. Combo boxes are populated dynamically in the table. They have “id” what is their numeric number in the table: for example wcboTechnique1, wcboInstrumentGroup1; wcboTechnique2, wcboInstrumentGroup2, etc.

I also have to use onLostFocus event to explicitly specify the selected row. Otherwise, “Any for technique” will be selected.

"InsertAtTop" doesn't do anything, since "Any for technique" is populated immediately and at the top anyway while the rest of the combo is populated a couple seconds later.

Thanks, Ellen

function onInstrumentGroupShowDropDown(id) {

    var combo2 = ISGetObject("wcboInstrumentGroup" + id);

    var newRow;   

    rows = combo2.GetRows();

    if (rows[0]) {

        cells = rows[0].GetCells();

        if (cells.GetNamedItem("Description")) {

            if (cells.GetNamedItem("Description").Text != "Any for technique") {

                newRow = combo2.NewRow("-1");

                cells = newRow.GetCells();

                cells.GetNamedItem("Description").Text = "Any for technique";                

                rows.Add(newRow);

                combo2.InsertAtTop = true;               

                combo2.UpdateUI();                    

            }

        } else {

            newRow = combo2.NewRow("-1");

            cells = newRow.GetCells();

            cells.GetNamedItem("Description").Text = "Any for technique";           

            rows.Add(newRow);

            combo2.InsertAtTop = true;

            combo2.UpdateUI();           

        }

    } else {

        newRow = combo2.NewRow("-1");

        cells = newRow.GetCells();

        cells.GetNamedItem("Description").Text = "Any for technique";

        rows.Add(newRow);

        combo2.InsertAtTop = true;

        combo2.UpdateUI();       

    }  

}

function onInstrumentGroupLostFocus(id) {

    // Since "Any for technique" is added on ShowDropDown event, it is highlighted automatically even if

    // another InstrumentGroup is selected. hdnInstrGroupDesc is set based on intentionally selected InstrumentGroup

    // and helps to retain the correct value.

    var combo2 = ISGetObject("wcboInstrumentGroup" + id);

    var selectedText = combo2.Text;

    if (combo2.Text == "Any for technique" && combo2.Value == "") {

        eval("document.all.hdnInstrGroupDesc" + id).value = combo2.Text;

    }  

    var InstrGroupDesc = eval("document.all.hdnInstrGroupDesc" + id).value;   

    combo2.SetText(InstrGroupDesc);

}

Hi Martin,

I tried the code (“var wcCategory = ISGetObject(controlId)” is not used) and it has the same problem that I have been struggling with:

“wcProduct.ShowDropDown();” doesn’t open dropdown, it only shows DropDown symbol (as said in the Reference). The element Rows of wcProduct is still null and no row can be selected.

Thank you,

Ellen

Thank you, Handy.

Yudi,

"cbo2.LoadValue();" is what I didn't know about. It fixed the problem.

Thank you!
