Question

I am using the jQuery DatePicker control. The control displays properly but I am unable to get the selected value in my code behind page. I attempt to capture the user-selected value using: DateTime StartDt = Convert.ToDateTime(Request.Form[“datepicker”]); The user has several controls to select and then hits submit.

After submitting, when I inspect that value of StartDt it is: 01/01/0001 00:00:00AM

ASPX page:

<%@ Page Title="Fox Cities Restaurant Guide-Food Events" Language="C#" MasterPageFile="~/main_master.Master" AutoEventWireup="true" CodeBehind="Events.aspx.cs" Inherits="FCGuide.Events" %>

Code Behind page:

protected void btnFindEvents_Click(object sender, EventArgs e)
{
    string EventType = ddlEventType.SelectedValue;
    DateTime StartDt = Convert.ToDateTime(Request.Form["datepicker"]);
    string City = ddlEventCity.SelectedValue;

        BLgetEvents obj = new BLgetEvents();
        var EventList = obj.getAllEvents(StartDt);

        ListEvents.DataSource = EventList;
        ListEvents.DataBind();
    }

Answer 1

change your .aspx code to this:

<input id="datepicker" type="text" size="50px" maxlength="12" name="DatePickername" />

then in your codebehind, do:

 string dt = Request.Form["DatePickername"];
