private void InsertInfo()
{
SqlConnection conn = new SqlConnection(GetConnectionString());
string sql = "INSERT INTO PurchaseProduct(ProductCategoryId,ProductID,ProductName,BrandName,Price,Quantity,TotalPrice)values(@Val1,@Val2,@Val3,@Val4,@Val5,@Val6,@Val7)";
try
{
conn.Open();
SqlCommand cmd = new SqlCommand(sql, conn);
cmd.Parameters.AddWithValue("@Val1",Txtcatid.Text);
cmd.Parameters.AddWithValue("@Val2",Txtproductid.Text);
cmd.Parameters.AddWithValue("@Val3",Txtproductname.Text);
cmd.Parameters.AddWithValue("@Val4",Txtbrandname.Text);
cmd.Parameters.AddWithValue("@Val5",Txtproductprice.Text);
cmd.Parameters.AddWithValue("@Val6",Txtproductquantity.Text);
int Total = int.Parse(Txtproductprice.Text) * int.Parse(Txtproductquantity.Text);// (Convert.ToInt32(Txtproductprice.Text) * Convert.ToInt32(Txtproductquantity.Text));
string total = Convert.ToString(Total);
Txttotalprice.Text = Total.ToString();
cmd.Parameters.AddWithValue("@Val7",Total);
cmd.CommandType = CommandType.Text;
cmd.ExecuteNonQuery();
}
catch (System.Data.SqlClient.SqlException ex)
{
string msg = "Insert Error:";
msg += ex.Message;
throw new Exception(msg);

}
finally
{
conn.Close();
Txtcatid.Text = "";
Txtproductid.Text = "";
Txtproductname.Text = "";
Txtbrandname.Text = "";
Txtproductprice.Text = "";
Txtproductquantity.Text = "";
Txttotalprice.Text = "";

Should be like this ...TotalPrice) values...

int Total = int.Parse(Txtproductprice.Text) * int.Parse(Txtproductquantity.Text);// (Convert.ToInt32(Txtproductprice.Text) * Convert.ToInt32(Txtproductquantity.Text));

Txttotalprice.Text = Total.ToString();
cmd.Parameters.AddWithValue("@Val7",Total);

replace with

int Total = int.Parse(Txtproductprice.Text) * int.Parse(Txtproductquantity.Text);
string total = Convert.ToString(Total);
Txttotalprice.Text = total ;
cmd.Parameters.AddWithValue("@Val7",total);

this is method not a function

int Total = int.Parse(Txtproductprice.Text) * int.Parse(Txtproductquantity.Text);// (Convert.ToInt32(Txtproductprice.Text) * Convert.ToInt32(Txtproductquantity.Text));
string total = Convert.ToString(Total);
Txttotalprice.Text = Total.ToString();

you can directly assign,
int Total = int.Parse(Txtproductprice.Text) * int.Parse(Txtproductquantity.Text);
Txttotalprice.Text = Total.ToString();

It comes to something when someone who can't even manage to add the values of two numbers in textboxes is voting everyones answers as cold because they can't figure out the simplest of tasks!

It may also be worth while looking at TryParse to make sure the text boxes contain valid numbers.
