I think first try this command from command line prompt whether it is working fine or nor

no define at the page load event

SqlConnection con = new SqlConnection("server=servername;uid=sa;pwd=password;initial catalog=databasename");
String qry = "insert into tablename values(@id,@name,@imageurl,@price,@item)";
SqlCommand cmd = new SqlCommand(qry,com);
try
{
cmd.Paramaters.AddWithValues("@id",id);
cmd.Paramaters.AddWithValues("@name",name);
cmd.Paramaters.AddWithValues("@imageurl",imageurl);
cmd.Paramaters.AddWithValues("@price",price);
cmd.Paramaters.AddWithValues("@item",item);
con.Open();
cmd.ExecuteNonQuery();
}
catch(Exception ee)
{
}
finally
{
if (con.State == ConnectionState.Open)
{
con.Close();
}
}

Also before that include the following namespaves:
1. System.Data
2. System.Data.SqlClient

and initialize the variables used

download the file in the virtual folder and check the duplication of the file or five the file name along with the random number as filename and show the download link to download the file.

Give the source path as the url of the page that is used and desitination as the location where to save the pdf file

The first parameter is the name of the file/page that is to be converted to the pdf file, the second parameter is name of the file by which it is to be saved in pdf format

The first parameter is the name of the page that is to be converted whether it is *.aspx or *.html; the second parameter is the name of file by which you want to save the file

With the Microsoft.Office.Interop.Word assembly, we get the contents and formatting from the document.

Tip:
Add the Microsoft.Office.Interop.Word assembly to your project. Go to Project -> Add Reference...

To Read File:

using System;
using Microsoft.Office.Interop.Word;

class Program
{
static void Main()
{
// Open a doc file.
Application application = new Application();
Document document = application.Documents.Open("C:\\word.doc");

// Loop through all words in the document.
int count = document.Words.Count;
for (int i = 1; i <= count; i++)
{
// Write the word.
string text = document.Words[i].Text;
Console.WriteLine("Word {0} = {1}", i, text);
}
// Close word.
application.Quit();
}
}


To Write File:

var document = new DocumentModel();

// Add document content.
document.Sections.Add(
new Section(document,
new Paragraph(document, "Hello world!")));

// Save the document to a file.
document.Save("Document.docx");

// Open the document file with Microsoft Word.
Process.Start("Document.docx");

("select * from '" + ComboBox1.SelectedValue.ToString() + "'
union
select * from '" + ComboBox2.SelectedValue.ToString() + "'
union
select * from '" + ComboBox3.SelectedValue.ToString() + "')

Refer the link for details, regarding how to user validation controls within updatepanel.

Then send the code for aspx file and .cs file, then only i can check for the problem

Before the UpdatePanel tag

I don't want to use AJAX call.

Provide me the code so that i can review the root cause.
