Hi,
I made a simple report CrystalReport1.rpt which was added to my project (Add New Item => Crystal Report).
Now I want to use this report in my project, When i tried to write code in the code behind of the webform "CrystalReport1" code snippet did not appear. Then I typed the name of the report in the code:
CrystalReport1 = new CrystalReport1();
But I get this compile-error:
The type or namespace name 'CrystalReport1' could not be found (are you missing a using directive or an assembly reference?)
What is wrong?
Plz help.

Yes,
Add the foll. references to your project.
CrystalDecisions.CrystalReports.Engine<br />
CrystalDecisions.ReportSource<br />
CrystalDecisions.Shared<br />
CrystalDecisions.Web
and in your code behind file, import all the above references.
Hope this helps.

using CrystalDecisions.Shared;
using CrystalDecisions.ReportSource;

OK.
Hope you also added reference ("Add Reference..") to your project. Check again

Just now I added it by right clicking on my project solution explorer and select "Add reference" and selected
* CrystalDecisions.CrystalReports.Engine.dll
* CrystalDecisions.ReportSource.dll
* CrystalDecisions.Shared.dll
and clicked ok.
In the code behind i added these classes.
Even now i am unable to get the Report name in the codebehind snippet.
Plz let me know your thoughts.

Can you tell me how can i confirm that these references were added to my project.
I couldn't see any difference even after adding these references.

For an update, Just now I googled and found that We must get the "References node" after added the references.
But I am not getting it. 
Plz let me know how to get it.

Hi
Added references should appear in the project explorer under 'References'.
If not add again.

Harini,
I'm following these steps correctly.
When i binded a simple report using CrystalReportViewer control (with out using any dataset), It worked fine. (There is no code in the codebehind except the CrystalReportViewer bind property) It showed the values correctly.
When I tryed the same with the dataset in the code behind i am unable to get the reportname in the snippet.
CrystalReport1 crReportDocument = new CrystalReport1(); --> i'm not getting this report name here.
I am a fresher i don't know much about this. Is it compulsory to get the references node in the solution explorer to get the report name in the code behind.
Plz let me know your thoughts.

Hi Sonia,
You better try this code using vb.net
Response.Buffer = True
Response.AddHeader("content-disposition", "attachment;filename=RegisteredUsers.xls")
Response.ContentType = "application/vnd.ms-excel"
Response.Charset = ""
Me.EnableViewState = False
Dim oStringWriter As System.IO.StringWriter = New System.IO.StringWriter()
Dim oHtmlTextWriter As System.Web.UI.HtmlTextWriter = New System.Web.UI.HtmlTextWriter(oStringWriter)
oHtmlTextWriter.WriteLine("Registered Users: ")
'Me.ClearControls(dgGrid)
DataGrid1.RenderControl(oHtmlTextWriter)
Response.Write(oStringWriter.ToString())
Response.End()

Hi Venkatesh,
I Hosted through CUTE FTP.I hosted one simple html page also that is working .If we are adding any asp controls in the page then it will not work,it will not show that controls in the page,but it will show HTML controls.when i take the source of the page i could see the controls value eg : Label.text="welcome" but it will not show in the page.

No Kurian,
I asked whether you published the website and then hosted it or simply hosted it into the server.
