I am beginer in asp.net. I have created a form. When i submit that form i need to insert the form field values into a table in oracle database schema. I am using Visual Studio 2012 Express. I have already added my database schema to database explorer. Now I need a code to get data from form and insert into table.

Please help me to complete the form action.
Here is simple method to insert data, you can modify it to your needs
public void InsertToOracle(string value)
{
string oradb = "Data Source=ORCL;User Id=user;Password=password;";
using (OracleConnection conn = new OracleConnection(oradb))
{
conn.Open();
OracleCommand cmd = new OracleCommand();
cmd.Connection = conn;
cmd.CommandText = "Insert into Table1(ColumnName) VALUES(#ParameterName)";
cmd.Parameters.Add(new OracleParameter("#ParameterName", value));
var rowsUpdated = cmd.ExecuteNonQuery();
}
}
In addition in asp.net web forms no needs to use Request.Form
instead of
tkt_category = Request.Form["TicketCategoryTextBox"];
use
tkt_category = TicketCategoryTextBox.Text;
instead of
Activity_type = Request.Form["ActivityTypeDropDown"];
use
Activity_type = ActivityTypeDropDown.SelectedValue;
All items marked with runat=server are ready to use as a object variable

I'm creating a web site in vs 2017. I have a web form for logging in, which is verified against the web app database, and everything seems to work. However, when I log in to my web page, the loginView doesn't change. I am expecting some kind of display that the user has successfully logged into the web page.
Here's my code:
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
private string mycon = WebConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
private bool ValidateUser(String username, String password)
{
bool status;
SqlConnection con = new SqlConnection(mycon);
String myquery = "select * from customer";
SqlCommand cmd = new SqlCommand();
cmd.CommandText = myquery;
cmd.Connection = con;
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = cmd;
DataSet ds = new DataSet();
da.Fill(ds);
String uname;
String pass;
uname = ds.Tables[0].Rows[0]["userName"].ToString();
pass = ds.Tables[0].Rows[0]["password"].ToString();
con.Close();
if (uname == username && pass == password)
{
Session["username"] = uname;
status = true;
}
else
{
status = false;
}
return status;
}
protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
{
if (e.Authenticated)
{
Response.Redirect("Home.aspx");
}
if (ValidateUser(Login1.UserName, Login1.Password))
{
Response.Redirect("Home.aspx");
}
else
{
e.Authenticated = false;
}
}
}
and here is my login.aspx

here is my home.aspx which the user will go to after logging in :
<%# Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="home.aspx.cs" Inherits="_Default" %>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

<th colspan="3">
<asp:image runat="server" Height="250px" ImageUrl="~/images/makeup.png" Width="300px"></asp:image>
</th>
</tr>
</table>
</asp:Content>
there is no code behind for this page.
And this is my LoginView Control (it is located in the master page):
<th colspan="1" class="auto-style1">
<asp:LoginView ID="LoginView1" runat="server">
<AnonymousTemplate>
Hello,<br />
<asp:LoginStatus ID="LoginStatus1" runat="server" CssClass="auto-style3" />
</AnonymousTemplate>
<LoggedInTemplate>
<span class="auto-style3">Welcome back,</span><br class="auto-style2" />
<asp:LoginName ID="LoginName1" runat="server" CssClass="auto-style3" />
<br />
<asp:LoginStatus ID="LoginStatus2" runat="server" CssClass="auto-style2" />
</LoggedInTemplate>
</asp:LoginView>
</th>
i finally figured it out . so my error was in my login.aspx code behind page in this statement :
if (e.Authenticated)
{
Response.Redirect("Home.aspx");
}
if (ValidateUser(Login1.UserName, Login1.Password))
{
Response.Redirect("Home.aspx");
}
else
{
e.Authenticated = false;
}
so i think that e.authenticated = true didn't reach the login view because i redirected my self to the other page so all you need to do is to :
if
if (ValidateUser(Login1.UserName, Login1.Password))
{
e.Authenticated = true;
}
else
{
e.Authenticated = false;
}
and make sure to set the login property DestinationPageUrl to what you want the user to go after login .
I am trying to clear the form on cancel button click with a function clearForm() that uses String.Empty with each field of the form but this is not working. I am neither getting any error nor getting the expected result.

using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.Globalization;
public partial class AddEmployee : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btn_ClearForm(object sender, EventArgs e) //to clear form on IsPostBack or on press of cancel button
{
if (!IsPostBack)
{
clearForm();
}
}
#region public functions
public void clearForm()
{
txtName.Text = String.Empty;
txtAddress.Text = String.Empty;
txtDoB.Text = String.Empty;
txtDesig.Text = String.Empty;
txtSal.Text = String.Empty;
txtEmail.Text = String.Empty;
txtUser.Text = String.Empty;
txtPass.Text = String.Empty;
txtConfPass.Text = String.Empty;
GenderList.Items[0].Selected = true;
GenderList.Items[1].Selected = false;
}
#endregion
}
There is nothing wrong with string.Empty. But you do not need condition in btn_ClearForm as btn_ClearForm handler will always called on postback and you put the condition if !IsPostBack
// if (!IsPostBack)
//{
clearForm();
// }
Your code would be
protected void btn_ClearForm(object sender, EventArgs e)
{
clearForm();
}
Got the fix!
Just use CausesValidation="false" on the cancel button so as to disable validation upon cancel button click event.
Because when you have used validation on your controls without using CausesValidation="false" on the cancel button, your controls will be forced to pass through validation conditions given to them and since the cancel button is meant to clear your form regardless of checking the validity of the data in form fields, the form will get stuck.
So whenever you have used validation conditions on your controls, just make sure you don't get them fired on the click of Cancel/clear/reset button.
Thanks
I have a Boolea(bit) value in database and i shown it in Grid View in the cell no. 2 like this
MyGrdView.SelectedRow.Cells[2] // for any row selected this cell have a boolean value 0 or 1

I need in another View (view2), i can shown this value in check box, so if the boolean cell in gridview have 0, the check box checked and for 1 the check box unchecked

The update doesn't work successfully. I mean it does not reflect in database. It just according to code, redirects to the specified page. Please help me where i am going wrong.
Actually the problem is now solved. I thank all of you for your concerns.
The problem was solved by just putting if not postback condition.
if (!Page.IsPostBack)
{
if (Request.QueryString["P_Id"] != null)
{
....
}
}
I have added DropDownList1 in Default.aspx page my ASP.Net project, and I have the below code in Default.cs:
if(DropDownList1.SelectedItem.ToString()=="")
I got this error:
Error 2 The name 'DropDownList1' does not exist in the current context
Edit:
In *.cs:
protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
{
string username = Login1.UserName;
string pwd = Login1.Password;
var connstring = ConfigurationManager.ConnectionStrings["ApplicationServices"].ConnectionString; ;
var conn = new SqlConnection(connstring);
conn.Open();
SqlCommand command;
if(DropDownList1.SelectedItem.ToString()=="")
command = new SqlCommand("Select [ID] from [Inspector] WHERE [ID] =" + username + " AND [Password] ='" + pwd + "';", conn);
SqlDataReader dr = command.ExecuteReader();
if (dr.Read())
{
if (dr[0].ToString() == username)
{
Session["UserAuthentication"] = username;
Session.Timeout = 1;
Response.Redirect("MainInspector.aspx");
}
else

You need to check your markup to confirm that the ID matches i.e.
<asp:DropDownList id="DropDownList1".....
If it is a web application the designer.cs file could be messed up as this has the reference within it.
Something like this:
protected global::System.Web.UI.WebControls.DropDownList DropDownList1;
If it is missing try adding the above.
Such errors might appear when the markup in the .aspx page (or .ascx control) is not well formed. In cases where the markup is bad, when you add a new control its declaration is not added in the designer file and leads to this error.
If this is the case, one common trick to fix this is to cut and paste the markup of the control. This way you re-add the control and make Visual Studio to re-add the declaration of the control in the designer file.
DropDownList1 does not exist in the current context
The solution for me was to place the DropDownList outside of of the LoginView.
Try moving the DropDownList to another section of your page and see if this works.
