I am trying to get validation where i can check what user inter in TextBox is valid PartNumber which is in my database.
My asp page looks like . and code behind is
<table width="50%" border="1" align="center">
<tr>
<td width="30%" class="style1">
<b>Part Number :</b>
</td>
<td class="style1">
<asp:TextBox ID="lpartno" runat="server" Width="300px"></asp:TextBox>
<cc1:AutoCompleteExtender ServiceMethod="GetCompletionListPartno" MinimumPrefixLength="1"
CompletionInterval="1" EnableCaching="false" TargetControlID="lpartno"
ID="AutoCompleteExtender2" runat="server" FirstRowSelected="false">
</cc1:AutoCompleteExtender>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="lpartno" TargetControlID="lpartno" ErrorMessage="PartNumber is Required" ForeColor="Red"></asp:RequiredFieldValidator>
</td>
</tr>
<tr>
<td width="30%">
<b>Reveived Date :</b>
</td>
<td>
<asp:TextBox ID="lReceivedDate" runat="server" CausesValidation="True" ></asp:TextBox>
<cc1:CalendarExtender ID="lReceivedDate_CalendarExtender" runat="server" Enabled="True"

<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="lReceivedDate" TargetControlID="lReceivedDate" ErrorMessage="Reveived Date is Required" ForeColor="Red"></asp:RequiredFieldValidator>
</td>
</tr>
<tr>
<td width="30%">
<b>PO Number :</b>
</td>
<td>
<asp:TextBox ID="lPONo" runat="server" Width="300px"></asp:TextBox>
<cc1:AutoCompleteExtender ServiceMethod="GetCompletionListPONo" MinimumPrefixLength="1"

<asp:RequiredFieldValidator ID="RequiredFieldValidator3" runat="server" ControlToValidate="lPONo" TargetControlID="lPONo" ErrorMessage="PO Number is Required" ForeColor="Red"></asp:RequiredFieldValidator>
</td>
</tr>
I would like to have validation we i can check the Part number user is entering is in my database table. if not it should so some error message.
Please advice how i will achieve this !!
Thanks in advance !!

This is the way I solved this problem
protected void CustomValidator2_ServerValidate(object source, ServerValidateEventArgs args)
{
args.IsValid = false;
string StaffID = lpartno.Text;
SqlConnection conn = new SqlConnection();
conn.ConnectionString = ConfigurationManager.ConnectionStrings["eFoxNetConnectionString"].ConnectionString;
SqlDataAdapter da = new SqlDataAdapter("select distinct PartNo from dbo.FTX_SAPPO sp with (nolock) where PartNo=#ID",conn);
da.SelectCommand.Parameters.Add("#ID", SqlDbType.VarChar, 120);
da.SelectCommand.Parameters["#ID"].Value = StaffID;
DataSet ds = new DataSet();
da.Fill(ds);
if (ds.Tables[0].Rows.Count > 0)
args.IsValid = true;
}

How to stop loading the whole HTML page in registration form ? - ASP.NET

I'm working with ASP.NET web application . i have done a registration form but whenever the user type the Username or Email it will loads whole first_home page ! how i can stop loading the whole page ? i have setup a constraint in the database for the Username and Email to avoid the duplication.
the HTML code:
<table align="left" class="auto-style8" dir="rtl">
<tr>
<td class="auto-style13">username </td>
<td class="auto-style10">
<br />
<asp:TextBox ID="TextBoxUsername" runat="server" AutoPostBack="true" Height="25px" Width="223px" ForeColor="#990033" OnTextChanged="TextBoxUsername_TextChanged"></asp:TextBox>

<td class="auto-style11">

<br />

<td class="auto-style11">

<td class="auto-style10">
<asp:Button ID="Button6" runat="server" OnClick="Button6_Click" Text="done" ForeColor="#990033" />
</td>
<td class="auto-style11"> </td>
<td> </td>
</tr>
</table>
the first_home.aspx.cs code:
public partial class First_home : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
{
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["MyDatabase"].ConnectionString);
conn.Open();
// check if the username is taken before
string checkuser = "Select count(*) from Users where Username='" + TextBoxUsername.Text + "'";
SqlCommand com = new SqlCommand(checkuser, conn);
int temp = Convert.ToInt32(com.ExecuteScalar().ToString());
if (temp == 1)
{ Response.Write("error"); }
conn.Close();
}
}
protected void Button6_Click(object sender, EventArgs e)
{
try
{
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["MyDatabase"].ConnectionString);
conn.Open();
string insertQuery = "insert into Users (Username,Password,Email) values (#username, #password, #email)";
SqlCommand com = new SqlCommand(insertQuery, conn);
com.Parameters.AddWithValue("#username", TextBoxUsername.Text);
com.Parameters.AddWithValue("#password", TextBoxPassword.Text);
com.Parameters.AddWithValue("#email", TextBoxEmail.Text);
com.ExecuteNonQuery();
conn.Close();
Response.Redirect("Seller_Registration.aspx");
}
catch (Exception ex)
{ Response.Write("error "); }
}
also the database CONSTRAINT :
CONSTRAINT [AK_Users_Email] UNIQUE NONCLUSTERED ([Email] ASC),
CONSTRAINT [AK_Users_Username] UNIQUE NONCLUSTERED ([Username] ASC),

Remove the AutoPostBack="true" attribute from those two controls.
Those two controls are causing PostBack whenever you are typing something and focusing out of that control. That is the reason behind the whole page load.

String.Empty not working on button click

using System.Data;
using System.Data.SqlClient;
using System.Globalization;
public partial class AddEmployee : System.Web.UI.Page

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

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

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.
