                <asp:ListItem>31</asp:ListItem>
            </asp:DropDownList>
            <asp:DropDownList ID="purchinvoice_dropdownlist_monthdate" runat="server" CssClass="dropdownliststyle">
                <asp:ListItem>month</asp:ListItem>
                <asp:ListItem>1</asp:ListItem>
                <asp:ListItem>2</asp:ListItem>

                <asp:ListItem>11</asp:ListItem>
                <asp:ListItem>12</asp:ListItem>
            </asp:DropDownList>
            <asp:DropDownList ID="purchinvoice_dropdownlist_yeardate" runat="server" CssClass="dropdownliststyle">
                <asp:ListItem>Year</asp:ListItem>
                <asp:ListItem>2010</asp:ListItem>
                <asp:ListItem>2011</asp:ListItem>
                <asp:ListItem>2012</asp:ListItem>
                <asp:ListItem>2013</asp:ListItem>
                <asp:ListItem>2014</asp:ListItem>
                <asp:ListItem>2015</asp:ListItem>
                <asp:ListItem>2016</asp:ListItem>
                <asp:ListItem>2017</asp:ListItem>
                <asp:ListItem>2018</asp:ListItem>
                <asp:ListItem>2019</asp:ListItem>
                <asp:ListItem>2020</asp:ListItem>
                <asp:ListItem>2021</asp:ListItem>
                <asp:ListItem>2022</asp:ListItem>

                <asp:ListItem>2025</asp:ListItem>
            </asp:DropDownList>

and the class is:

  public class purchinvoice
{
    public string purch_serial_number;
    public string sup_name;
    public DateTime p_date;

    public purchinvoice()
    {
        purch_serial_number = null;
        sup_name = null;
        p_date = new DateTime();
    }
    public bool add_purchinvoice(out string msg)
    {
        msg = "";
        bool b = true;
        SqlConnection con = new SqlConnection(DBconnection.connectstr);
        try
        {
            con.Open();
            SqlCommand com = new SqlCommand("add_purch_invoice", con);
            com.CommandType = CommandType.StoredProcedure;
            com.Parameters.Add("@purch_serial_number", SqlDbType.NVarChar).Value = this.purch_serial_number;
            com.Parameters.Add("@sup_name", SqlDbType.NVarChar).Value = this.sup_name;
            com.Parameters.Add("@p_date", SqlDbType.DateTime).Value = this.p_date;
            com.ExecuteNonQuery();
            con.Close();
            b = true;
        }
        catch (Exception ex)
        {
            b = false;
            msg = ex.Message;
            con.Close();

        }
        return b;
    }

Answer 1

You are calling the DateTime constructor incorrectly.

According to MSDN , there is a DateTime Constructor overload that can take 3 parameters. ie

public DateTime(int year, int month, int day) 

You are passing the parameters in the wrong order.

Try changing your code behind to use this instead.

pi.p_date = new DateTime(
    int.Parse(purchinvoice_dropdownlist_yeardate.SelectedItem.Text),        
    int.Parse(purchinvoice_dropdownlist_monthdate.SelectedItem.Text),
    int.Parse(purchinvoice_dropdownlist_daydate.SelectedItem.Text) 
);

You should also probably make sure that the Text fields can actually be parsed to integers, otherwise you will still receive an exception if the user supplies invalid values.

Insert this code in the html page:

<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
    <link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css" />

    <link rel="stylesheet" href="/resources/demos/style.css" />
    <script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>

    <script type="text/javascript">

        $(document).ready(function () {

            $("#TextBox3").datepicker({

                showOn: 'both',
                buttonText: 'Select',
                dateFormat: 'yy/mm/dd',
                chnageMonth: true,
                changeYear: true,

            });

        });

    </script>

And call the values from this code in C#:

string Issue_Date = TextBox3.Text;
DateTime Date = Convert.ToDateTime(Issue_Date);
Console.WriteLine( Date.Year + "" + Date.Month + "" + Date.Day);

Answer 3

Try using the ASP.NET Calendar control instead. It will save you a lot of time.

Answer 4

Try "DateTime.Parse".

    DateTime.Parse
    (
    purchinvoice_dropdownlist_monthdate.SelectedItem.Text + "/" + 
    purchinvoice_dropdownlist_daydate.SelectedItem.Text + "/" + 
    purchinvoice_dropdownlist_yeardate.SelectedItem.Text
    );
