Static variable should not be used in Web Applications, because they have application level scope, not session level. So, they will retain values across users.

But when multiple users use the application in one time to there is a problem if i am using static variable
also i can not customize the third party control to clear cookies and session.

I would advise you to store the DataTable records in a file or in a Table in Database. Then retrieve the data again in other page and reuse it.

If user not going to the other page then Database fill anonymously and also file.

Don't you need that data to be stored anywhere? Is it temporary only?

ksmtariqzafar 27-Dec-14 9:58am

No if third party tool will authorize the user then save the first form data in database other wise if third party tool reject the user then no data will be saved.

Okay, you have the logic in place. So, if it authorized, the. Save, else don't. Then if you go to the next page, retrieve the data from that table, if the data is there, then show it. Simple.

if the user don't go to the next page to authenticate him/her self and will put the data multiple times to this data is useless. i need the user first to authenticate then save the data

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 27-Dec-14 10:21am

Tell me the flow. When exactly you want to save? I am little confused.

Page 1: Save some temporary information from the user.
Page 2: third part tool that authenticate the user.
when authenticates it nulls the session and cookies of browser.
Page 3: If page 2 authenticates then save the first page information.
if not authenticate then not save the information.

Okay, so what you can do is... On Page 1, save the info in a Temporary place either in database or file.

In Page 3, if Authenticated, then retrieve the info and show, if not Authenticated, then delete that info from temporary location.

The Third party app... deleting all the sessions and cookies

but I got the solution.

On First page C# Code:

DataSet dsinfo = new DataSet();
dsinfo.Tables.Add(dtInfo);
XmlDataDocument xmldatainfo = new XmlDataDocument(dsinfo);
XmlElement xmlElementinfo = xmldatainfo.DocumentElement;
string xml_stringinfo = xmldatainfo.OuterXml.ToString();
Session["dtInfo"] = xml_stringinfo;

On third Party page Passing Hidden input
Like this: under form tag

HTML

<input type="hidden" name="FeeDetailinfo" value="<%=Session["dtInfo"] %>" />

and one third page retrieve the input in c# code
Like this:

DataTable dtinfo = new DataTable();
DataSet dsinfo = new DataSet();
StringReader readerinfo = new StringReader(Request.Form["FeeDetailinfo"]);
dsinfo.ReadXml(readerinfo);
dtinfo = dsinfo.Tables[0];
