radgrid custom filter template with clientside events disable another js events

[archimede]

Hi,
I create a server control that create programmatically a grid  with template columns, filter templates , ecc.
Evrithing works fine, but i noticed that when i introduced the MyFilterTemplate class to generate the filter items for any column, if the item (radcombobox, raddatapicker, ecc) include a clientside event then others controls outside the grid  doesn't work propertly.
For example i have a raddatepicker with a DatePopupButton visible outside the grid , after the page load if i click the popupbutton it shows the popup fine; but after an edit/insert of a value in the grid the popupbutton don't show the popup !.
So, my question is, how a programatically definition of a filter template column with clientside events may cause undesired operation of others controls..

This is the code of my filter template class... that as i said before it works perfectly on the grid.

private class MyFilterColumn : ITemplate
        {
            private Telerik.Web.UI.RadComboBox combo;
            private RadDatePicker _rdp;
            protected CommonParameters.GridTemplateColumnType type;
            protected string fieldvalue;
            protected string fieldtext;


            public MyFilterColumn(string Fieldvalue, string Fieldtext, CommonParameters.GridTemplateColumnType Type)
            {
                fieldvalue = Fieldvalue;
                fieldtext = Fieldtext;
                type = Type;
            }
            public void InstantiateIn(Control container)
            {
                switch (type)
                {
                    case CommonParameters.GridTemplateColumnType.ComboOnDemand:
                        {
                            combo = new Telerik.Web.UI.RadComboBox();
                            combo.ID = String.Format("RadComboBox{0}", fieldtext);
                            combo.AppendDataBoundItems = true;
                            if (fieldvalue.Length > 0)
                                combo.DataTextField = fieldtext.Substring(fieldtext.IndexOf(".") + 1, (fieldtext.Length - (fieldtext.IndexOf(".") + 1)));
                            combo.DataValueField = fieldvalue;
                            combo.EmptyMessage = "niente";
                            combo.Items.Insert(0, new Telerik.Web.UI.RadComboBoxItem("Tutti"));
                            combo.Enabled = true;
                            combo.DataBound += combo_DataBound;
                            combo.DataBinding += new EventHandler(combo_DataBinding);
                            combo.OnClientSelectedIndexChanged = String.Format("ClientComboFilterSelected_{0}", fieldvalue);
                            container.Controls.Add(combo);
                        }
                        break;
                    case CommonParameters.GridTemplateColumnType.Date:

                            _rdp.Width = new System.Web.UI.WebControls.Unit(CommonParameters.RadDatePickerWidth);
                            _rdp.DbSelectedDate = _rdpf_DataBinding((GridItem)container.NamingContainer);


                            string script = "function ClientDataPickerFilterSelected_" + fieldvalue + "(sender,args) {var tableView=$find(\""

Hi Francesco,

Could you please inspect your request when trying to open the Calendar component for second time and verify if any js errors appear on the page?

Kind regards,
