WebCombo ClientSide databind

Hello,

First of all, please forgive me for lack of understanding about the reported problem.

I have a simple WebCombo that using Client Binding operation mode.
This sample is show how to rebind the WebCombo to use another data source.
There are two WebCombo in this sample; the data in second WebCombo is depending on the first WebCombo’s value.

You could get the sample from this link.
Please have review on the sample and let me know whether this sample can help you or not.

Thank you very much.

Regards,
Hans.

I have following code:

function success(msg) {
    var combo = ISGetObject('cmbGodina');
    var rows = combo.GetRows();
//    if(rows.length > 0){
//        for(var i = 0; i < rows.length; ++i){
//            rows.Remove(rows[i], true);
//        }
//    }

//    combo.UpdateUI();
    var dataTable = new ISDataTable();
    var idColumn = new ISDataColumn(dataTable);
    var naziv = new ISDataColumn(dataTable);
    var datumDo = new ISDataColumn(dataTable);
    var xsltFile = new ISDataColumn(dataTable);
    var procFile = new ISDataColumn(dataTable);
    dataTable.Name = dataTable.TableName = "Root";
    idColumn.Name = idColumn.ColumnName = "IdObrasca";
    naziv.Name = naziv.ColumnName = "Naziv";
    datumDo.Name = datumDo.ColumnName = "DatumDo";
    xsltFile.Name = xsltFile.ColumnName = "XsltFile";
    procFile.Name = procFile.ColumnName = "ProcFile";
    dataTable.Columns.Add(idColumn);
    dataTable.Columns.Add(naziv);
    dataTable.Columns.Add(datumDo);
    dataTable.Columns.Add(xsltFile);
    dataTable.Columns.Add(procFile);
    $(msg).find('Table').each(function (i, row) {
        $(row).find('Field').text();
        var dataRow = dataTable.NewRow();
        dataRow.Cells.GetNamedItem("IdObrasca").Value = $(row).find('IdObrasca').text();
        dataRow.Cells.GetNamedItem("Naziv").Value = $(row).find('Naziv').text();
        dataRow.Cells.GetNamedItem("DatumDo").Value = $(row).find('DatumDo').text();
        dataRow.Cells.GetNamedItem("XsltFile").Value = $(row).find('XsltFile').text();
        dataRow.Cells.GetNamedItem("ProcFile").Value = $(row).find('ProcFile').text();
        dataTable.Rows.Add(dataRow);
    });
    combo.SetDataSource(dataTable);    
    combo.DataBind();
    combo.Render();    
}

msg is xml returned by webmethod on serverside. Everything works well, but I can't clear webcombo data before i bind it to another source. the commented lines of code, when uncommented, produce error "Unable to get value of the property 'rowIndex': object is null or undefined"

this is my combo:

<iswebcombo:WebCombo ID="cmbGodina" runat="server" AllowWildCardSearch="false" Width="200" 
                        Height="20" DataValueField="IdObrasca"
                        ViewStateStorage="None" BindingOperationMode="ClientBinding" DataTextField="Naziv">
                        <LayoutSettings ComboMode="MultipleColumns" EnableAnimation="False" AlwaysShowAllRowsOnDropdown="true" 
                            EntryMode="AutoComplete" StatusBoxPosition="Top" StatusBoxVisible="false">
                            <ClientSideEvents  OnAfterItemSelected="cmbGodina_OnAfterItemSelected" />
                        </LayoutSettings>
                        <Columns>
                            <iswebcombo:WebComboColumn Name="Naziv" HeaderText="<%$GetString:{%00_pub_Name%}%>" BaseFieldName="Naziv" Width="200" />
                            <iswebcombo:WebComboColumn Name="DatumDo" Hidden="true" RenderOnHidden="true" BaseFieldName="DatumDo" />
                            <iswebcombo:WebComboColumn Name="XsltFile" Hidden="true" RenderOnHidden="true" BaseFieldName="XsltFile" />
                            <iswebcombo:WebComboColumn Name="ProcFile" Hidden="true" RenderOnHidden="true" BaseFieldName="ProcFile" />
                        </Columns>
                        <ClientBindingSettings DataSourceType="ClientDataSource" />
                    </iswebcombo:WebCombo>
