I’m looking at code in an XYZ.aspx.cs that pertains to a drop down list. It is:
dt = SessionData.Report_RespondentAnswer(DateTime.Parse(tbFromDate.Text).ToString("yyyy-MM-dd"),
DateTime.Parse(tbToDate.Text).ToString("yyyy-MM-dd"),
SurveyID,
SupplierID,
LK_SurveyStatuses.GetResponseGroup_ResponseCodes(ddlResponseRange.SelectedValue),
LK_SurveyStatuses.GetResponseGroup_ClientResponseCodes(ddlResponseRange.SelectedValue));
And this corresponds to a drop-down that looks like this:
ddlResponseRange.SelectedValue
is this possile?

Edit Most browsers also have developer modes which are better for this sort of thing. Chrome for example has a great set of Developer Tools.
