How to extract information from database?

I am trying to create a Login page and validating the incoming details against the database. But my code isn't able to cross check data from the database. Below is the output result I'm getting from the application:

Would someone point out what's wrong with the code?

No need to fetch all the records from the database just to check a single result. Change your Button1_Click event code to this:
protected void Button1_Click(object sender, EventArgs e)
{
string username = txtemail.Text;
string password = txtpwd.Text;
using (SqlConnection sqlCon = new SqlConnection(#"Data Source=TEAFAMILY;Initial Catalog=Bolsen;Integrated Security=True; MultipleActiveResultSets=true;"))
{
string query = "SELECT Top(1) * FROM Customers WHERE cEmail = #Username and cPassword = #Password";
SqlCommand cmd = new SqlCommand(query, sqlCon);
cmd.Parameters.AddWithValue("#Username", username);
cmd.Parameters.AddWithValue("#Password", password);
sqlCon.Open();
SqlDataReader rdr = cmd.ExecuteReader();
if (rdr.Read())
{
Session["sFlag"] = "T"; // sFlag = "T" means user has logged in
Session["sName"] = rdr["Firstname"];
Session["sEmail"] = rdr["cEmail"];
Session["sAddress"] = rdr["cCompanyAddress"];
Session["sEmail"] = rdr["cEmail"];
logoutbtn.Visible = true;
sqlCon.Close();
Response.Redirect("Default.aspx");
}
else
{
Session["sFlag"] = "F";
Session["sName"] = "";
Session["sUserId"] = "";
loginmessage.Text = "Error in login - Please login again ";
}
}
}

How to retrieving & display data from multiple tables under the same heading?

I am making an Employee Roster Scheduler.
Currently, I'm trying to use a repeater to display the current shifts in a calendar format.
Below is my current output:
As you can see, there are 2 shifts on Saturday. Does anyone know how I can place these two shifts under one header, so Saturday 03 June 2017 only appears once, rather than twice?
Below you can find my code:
HTML:
<div class="col-lg-12">
<asp:Repeater ID="repSubscription" runat="server" OnItemDataBound="repSubscription_ItemDataBound">
<ItemTemplate>
<div class="col-lg-2">
<div class="panel panel-default">
<div class="panel-heading" style="background-color: #3A6EA5; color: white">
<h4 class="panel-title">
<%# Eval("Start_Time", "{0:dddd, dd MMMM yyyy}") %>
</h4>
</div>
<!--panel-heading-->
<div class="panel-body">
<asp:Repeater ID="repShift" runat="server">
<ItemTemplate>
<b><%# Eval("Job_Title") %></b>
</ItemTemplate>
</asp:Repeater>
</br>
<asp:Repeater ID="repEmp" runat="server">

</ItemTemplate>
</asp:Repeater>
</div>
</div>
</div>
</ItemTemplate>
</asp:Repeater>

Code-behind:

string Group_Id = DataBinder.Eval(e.Item.DataItem, "Emp_ID").ToString();
cmd.Parameters.AddWithValue("#EmpId", Group_Id);
//Need to assign the Data in datatable
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
sda.Fill(dt);
repEmp.DataSource = dt;
repEmp.DataBind();
}
conn.Close();
}
, then I am happy to post it.
Thanks a lot for any help in advance!

Attaching an existing but modified entity to the context (Drop-down list from Database)

Experts,
Drop-down list is picking data from database and saving against the same column upon opening the web page and save the data, where saving is happening in another instead of same name,

databaseDATABASE DISPLAY

In order to update an item in a database, we first need to make sure we'll know which one we need to reference.
First, with the creation of your DropDownList, we'll want to hide the ID of the "PlaceInfo" we are displaying. This will create the need for a "SelectMethod", and a few other adjustments:
<asp:DropDownList ID="txtName" runat="server" ItemType="PlaceInfo" DataValueField="PlaceId" DataTextField="Name" SelectMethod="GetMyPlaces"></asp:DropDownList>
The DataTextField property is the one which will display in the actual DropDown, and the DataValueField is a hidden property which we will use to reference the ID so we can call that row later.
The SelectMethod (I have as: GetMyPlaces) is the method we use to populate the DropDownList. Please excuse the brevity, as you can do this a number of ways, but essentially you want to return a list of PlaceInfos:
public List<PlaceInfo> GetMyPlaces()
{
return new SampleDbEntities().PlaceInfoes.ToList();
}
Finally - in the btnSubmit_Click method, you want to grab the row we're going to edit by using the hidden Value field from the dropdown :
PlaceInfo placeToEdit = Context.PlaceInfoes.Find(Convert.ToInt32(txtName.Value))
Assign it the new values, and tell entity framework this model is now modified:
using (var context = new SampleDBEntities())
{
PlaceInfo placeToUpdate = context.PlaceInfoes.Find(Convert.ToInt32(txtName.Value));
placeToUpdate.Name = txtName.Text;
placeToUpdate.Address = txtAddress.Text;
placeToUpdate.Geolocation = DbGeography.FromText("POINT( "+hdnLocation.Value+")");
context.Entry(placeToUpdate).State = EntityState.Modified;
context.SaveChanges();
}
Save the changes to your context and you should be good to go.

Creating dynamic DIV in asp .net c#

I am creating DIVs dynamically which will fetch data from my sql table(from each row) and will show it in DIVs. What problem I am facing is, it only shows the last row of my sql table in a div form
Here is the html
<div ID = "containerDiv" class="container" runat = "server">
<div ID = "columnDiv" class="col-md-3 col-sm-4" runat = "server">
<div ID = "textDiv" class="text" runat="server">
</div>
</div>
</div>
and here is the cs code
static int count = 0;
protected void Page_Load(object sender, EventArgs e)
{
string CS = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
using (SqlConnection con = new SqlConnection(CS))
{
using (SqlCommand cmd = new SqlCommand("SELECT * FROM tblProducts"))
{
cmd.Connection = con;
con.Open();
SqlDataReader rdr = cmd.ExecuteReader();
while (rdr.Read())
{
columnDiv.ID = "columnDiv" + count;
textDiv.ID = "textDiv" + count;
string name = rdr["prod_name"].ToString();
string price = rdr["prod_price"].ToString();
textDiv.InnerHtml = name + " " + price;
columnDiv.Controls.Add(textDiv);
containerDiv.Controls.Add(columnDiv);
count++;
}
}
}
}

Try using a Repeater, like this (here's the MSDN):
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<div ID="containerDiv" class="container" runat = "server">
<div ID="columnDiv" class="col-md-3 col-sm-4" runat = "server">
<div ID="textDiv" class="text" runat="server">
</div>
</div>
</div>
</ItemTemplate>
</asp:Repeater>
And supply a DataSource in the code behind on the server, and add '<%# Eval("ColumnName") %>' expressions in the markup where appropriate.

The standard approach is to use a GridView:

I see you have already flagged your service as ScriptService, however you forgot to flag individual methods with the [ScriptMethod] attribute.
Also in the service path property of your cascading drop down controls I would take out the ~ and just use /dropdown.asmx
