Certainly...here is the EditFormSettings for the RadGrid where the ComboBox with the SelectedIndexChanged event is configured
<EditFormSettings EditFormType="Template" InsertCaption="Add a New Schedule" CaptionFormatString="Edit Schedule: {0}"
CaptionDataField="SchID" PopUpSettings-Width="500px">
<FormTemplate>
<div class="popuptitle">

<div class="clear">

<div class="popupbuttons">

</div>
</FormTemplate>
</EditFormSettings>
and here is the code behind for that event
I did not have EnableViewState set to false, however, when I attempted that, the postback after changing the ComboBox to another value doesn't save that change and returns me to the first selection the list again. So, if Call Response is the first item in the ComboBox and I use the dropdown to change to Call Detail, when the popup does a postback, I'm returned to Call Response again.
Thank you for your assistance...please let me know if you need anything to help troubleshoot this.
If you need the code for the BuildOptions function, here it is:
protected void BuildOptions(GridEditFormItem editFormItem)
{
RadComboBox dd_RptID = (RadComboBox)editFormItem.FindControl("dd_RptID");
EISDataContext db = new EISDataContext();
// get the unique report options for the current selected report so we can render the correct controls
var q_options = (from options in db.tReportConfigs
where options.RptID == dd_RptID.SelectedItem.Value
select options.OptID).Distinct();
foreach (var option in q_options)
{
string optionType = (from options in db.tReportOptions
where options.OptID == option
select options.OptTyp).FirstOrDefault();
string optionName = (from options in db.tReportOptions
where options.OptID == option
select options.OptNm).FirstOrDefault();
// get the option values for this option
var q_optionValues = from optionvalues in db.tReportConfigs
where optionvalues.RptID == dd_RptID.SelectedItem.Value && optionvalues.OptID == option
select optionvalues;
// create a div for the option control and populate it with the correct control
Panel panelContent = new Panel();
panelContent.Attributes.Add("class", "popupcontent");
if (optionType == "ComboBox")
{
RadComboBox combo = new RadComboBox();
combo.ID = "dd_" + option.ToString();
combo.Font.Size = 8;
foreach (var optionValue in q_optionValues)
{
combo.Items.Add(new RadComboBoxItem(optionValue.tReportOptionValue.OptNm, optionValue.tReportOptionValue.OptVal));
}
panelContent.Controls.Add(combo);
}
if (optionType == "DatePicker")
{
RadDatePicker dp = new RadDatePicker();
dp.ID = "dp_" + option.ToString();
panelContent.Controls.Add(dp);
}
// create a div for the option title and populate it with the option name
Panel panelTitle = new Panel();
panelTitle.Attributes.Add("class", "popuptitle");
Label pnlLabel = new Label();
pnlLabel.Text = optionName + ":";
panelTitle.Controls.Add(pnlLabel);
// create a div for the clear control
Panel panelClear = new Panel();
panelClear.Attributes.Add("class", "clear");
editFormItem.FindControl("divOptions").Controls.Add(panelTitle);
editFormItem.FindControl("divOptions").Controls.Add(panelContent);
editFormItem.FindControl("divOptions").Controls.Add(panelClear);
}
}
}
