Hi mavii what if like this? session("s1") = textBox1.Text; session("s2") = textBox1.Text; and in "crystalReportViewer1_Load" string s3 = session("s1"); string s4 = session("s2"); Is it solving the problem? (I am a new with CR also).

You can't, because the other page just doesn't exist anymore. You can do one of several things - 1 - store the value in the session ( as someone showed you ) 2 - put the value on the URL when you navigate to the second page ( the advantage of this is that your new page becomes bookmarkable )

can u plz explain your following sugesstion, i am not exactly getting what to do " put the value on the URL when you navigate to the second page ( the advantage of this is that your new page becomes bookmarkable )"
If you had a list of songs, for example, and you were going to a page that printed the lyrics, then if each song had an Id, each song title could be rendered as a link, but the links could be lyrics.aspx?songId=1 lyrics.aspx?songId=2 lyrics.aspx?songId=3 and so on. Then lyrics.aspx could read the songId from the query string and use it in a SQL query to retrieve the correct lyrics and render them.

He meant pass the values through URL as query string. So your URL will look like
yourpage.aspx?TextBox1Value=somevalue&TextBox2Value=somevalue. This can be taken in the page usingRequest.QueryString["TextBox1Value"]. And these type of URL's are bookmarkable, ie if you add this to bookmarks, it can be reloaded after some time. But if you use session and bookmarked the page, you can't reload it because session will be timed out.All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia My Website | Ask smart questions

Using query string is not safe regarding to security, whereas using session you can pass the value withouth user "see" it.

Choosing the method is always depends on the requirement. If security is not a main concern, query strings are the best, and in that case usage of sessions are not advised. Moreover as Christian told, the page will be book markable. But if security is the main concern, still you can use query string but after encrypting the value. I always prefer query strings, since it won't keep anything in the server memory as session does.

Tamper the Querystring Parameters. It's safe. Session Objects should be used only when you need a value through out the session accross the pages. When it's just a input parameter to generate a report which is not going to be the same every time you fetch the data then Query string is the best way here.

session is hide the data. that is what I called "secure". no matter encrypted or no, user still cannot deal with the value directly. session can store any datatype including datasource. thanks for sharing:)
