Registration form example to insert user details in database using asp.net

Introduction

Here I will explain how to insert registered user details in database and how to get output parameters returned by SQL Query in asp.net.

Description

I have one registration form that give a chance to register new user .In registration form user needs to enter fields UserName, Password, Confirm Password like this I have nearly ten fields are there now I need to check whether this username already exists or not if username not exists I need to register user otherwise I need to display message like username already exists I am doing this thing using query. Here is the link it will explain how to write sql query to return output parameters

http://www.aspdotnet-suresh.com/2010/10/introduction-here-i-will-explain-how-to.html

Now I need to display that output parameter message during user registration in asp.net. How to get that output parameter returned by SQL query.

To get output parameters in asp.net we need to write statements like this in codebehind

cmd.Parameters.Add("@ERROR", SqlDbType.Char, 500);
cmd.Parameters["@ERROR"].Direction = ParameterDirection.Output;
string message = (string) cmd.Parameters["@ERROR"].Value;

Here @ERROR is output parameter name returned from query

For sample design your aspx page like this

aspx page

<title>OutPut Pasrameters Sample</title>

</head>

<body>

<tr>

</td>

<b>Registration Form</b>

</td>

</tr>

<tr>

<asp:Label ID="lbluser" runat="server" Text="Username"></asp:Label>

</td>

<td>

<asp:TextBox ID="txtuser" runat="server"></asp:TextBox>

</td>

</tr>

<tr>

<asp:Label ID="lblpwd" runat="server" Text="Password"></asp:Label>

</td>

<td>

<asp:TextBox ID="txtpwd" runat="server" TextMode="Password"></asp:TextBox>

</td>

</tr>

<tr>

<asp:Label ID="lblcnfmpwd" runat="server" Text="Confirm Password"></asp:Label>

</td>

<td>

<asp:TextBox ID="txtcnmpwd" runat="server" TextMode="Password"></asp:TextBox>

</td>

</tr>

<tr>

<asp:Label ID="lblfname" runat="server" Text="FirstName"></asp:Label>

</td>

<td>

<asp:TextBox ID="txtfname" runat="server"></asp:TextBox>

</td>

</tr>

<tr>

<asp:Label ID="lbllname" runat="server" Text="LastName"></asp:Label>

</td>

<td>

<asp:TextBox ID="txtlname" runat="server"></asp:TextBox>

</td>

</tr>

<tr>

<asp:Label ID="lblemail" runat="server" Text="Email"></asp:Label>

</td>

<td>

<asp:TextBox ID="txtEmail" runat="server"></asp:TextBox>

</td>

</tr>

<tr>

<asp:Label ID="lblCnt" runat="server" Text="Phone No"></asp:Label>

</td>

<td>

<asp:TextBox ID="txtphone" runat="server"></asp:TextBox>

</td>

</tr>

<tr>

<asp:Label ID="lbladd" runat="server" Text="Location"></asp:Label>

</td>

<asp:TextBox ID="txtlocation" runat="server"></asp:TextBox>

</td>

</tr>

<tr>

<td align="left" ><asp:Button ID="btnsubmit" runat="server" Text="Save"

onclick="btnsubmit_Click" />

</td>

</tr>

<tr>

<td>

</td>

</tr>

</table>

</form>

</body>

</html>

In Codebehind write following code in btnsubmit_Click like this

Codebehind

protected void btnsubmit_Click(object sender, EventArgs e)

{

if (txtpwd.Text == txtcnmpwd.Text)

{

string UserName = txtuser.Text;

string Password = txtpwd.Text;

string ConfirmPassword = txtcnmpwd.Text;

string FirstName = txtfname.Text;

string LastName = txtlname.Text;

string Email = txtEmail.Text;

string Phoneno = txtphone.Text;

string Location = txtlocation.Text;

string Created_By = txtuser.Text;

SqlConnection con = new SqlConnection("Data Source=MYCBJ017550027;Initial Catalog=MySamplesDB;Integrated Security=True");

con.Open();

SqlCommand cmd = new SqlCommand("sp_userinformation", con);

cmd.CommandType = CommandType.StoredProcedure;

cmd.Parameters.AddWithValue("@UserName", UserName);

cmd.Parameters.AddWithValue("@Password", Password);

cmd.Parameters.AddWithValue("@FirstName", FirstName);

cmd.Parameters.AddWithValue("@LastName", LastName);

cmd.Parameters.AddWithValue("@Email", Email);

cmd.Parameters.AddWithValue("@PhoneNo", Phoneno);

cmd.Parameters.AddWithValue("@Location", Location);

cmd.Parameters.AddWithValue("@Created_By", Created_By);

cmd.Parameters.Add("@ERROR", SqlDbType.Char, 500);

cmd.Parameters["@ERROR"].Direction = ParameterDirection.Output;

cmd.ExecuteNonQuery();

message = (string) cmd.Parameters["@ERROR"].Value;

con.Close();

}

else

{

Page.RegisterStartupScript("UserMsg", "<Script language='javascript'>alert('" + "Password mismatch" + "');</script>");

}

lblErrorMsg.Text = message;

}

Here sp_userinformation is name of stored procedure created in database and@ERROR is output parameter name returned by query if you want to write query to insert data and return output parameters check this link
