Duplicate record on page refresh

There are many ways to check the page is refreshed or not.

You should make the database/store procedure strong to prevent any unnecessary or duplicate entry. As you don't have that much control over UI/client side.[Although there are many ways :) ].

So just place some condition in the database like, if the incoming data is already available then just return o status and inform user that data is already available.

Above all posted solutions are very good and you can also get some idea from it.

Hi,

One simple thing you can do.

Take procedure and write your insert code into that procedure.
Also put a if condition with record exists.

If record exists that return message that record exists. Else insert a value.

try this at the end of button_click event

.....
.....
DB.save();

//makesa round-trip of the same page
Response.Redirect(Request.Url.AbsolutePath);

Hello srinivasvempa,
1) You need change your code as bellow:

if (!IsPostBack)
{
// Your code to insert record into database
}

can You give me the solution in javascript?..

after saving complete
response.edirect("yourpage.aspx");

U will pass the header location and solve the problem....

header('Location:.php');
