Show Full Month Name and Full Path in AsyncUpload.

Using UI for ASP.NET AJAX Q1 2015 SP1 with VS 2013.
1) I would like to get Full Month Name (i.e. August, September etc..) from RadMonthYearPicker instead of integer value (i.e. 8, 9 etc). Refer to attachment_#_1.  code is here.

<telerik:RadMonthYearPicker ID="RadMonthYearPicker1"   AutoPostBack="true"  OnSelectedDateChanged ="btnSubmit_Click" runat="server"></telerik:RadMonthYearPicker>
 protected void btnSubmit_Click(object sender, EventArgs e)
    {
        string startmonth_year = RadMonthYearPicker1.SelectedDate.Value.Month.ToString() + " , " + RadMonthYearPicker1.SelectedDate.Value.Year.ToString();
        DateTime selectedDate = RadMonthYearPicker1.SelectedDate.Value;
        DateTime startDate = selectedDate.AddDays((selectedDate.Day - 1) * -1);
        DateTime endDate = startDate.AddDays(DateTime.DaysInMonth(startDate.Year, startDate.Month) - 1);
        Response.Write("Start Month and Year: "+startmonth_year + ' ' +  ' ' + ". Start Month beginning/end date: "+startDate.ToShortDateString() + " - " + endDate.ToShortDateString());
    }
2) How I can pass full file name path (\\Your_Server_Name\Your_Folder_Name\Your_File.csv) to Stored Procedure as Parameter or SSIS as variable? Or store the full file name path in string or session variable.

3) How I can show full file name path in Upload AsyncUpload  (i.e. \\Your_Server_Name\Your_Folder_Name\Your_File.csv). Refer to attachment_#2.

Thanks a lot
