In fact I'm using developer Express Tool called ASPxPageControl. In first tabPage, the last user enters the filter data then when clicks the button on this tabPage the report tabPage comes. T he hole code is like; 
&nbsp; &nbsp; &nbsp; &nbsp; try 
&nbsp; &nbsp; &nbsp; &nbsp; { 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; DateTime test; 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; test = Convert.ToDateTime(edt_Tarih_Bas.Text); 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; test = Convert.ToDateTime(edt_Tarih_Bit.Text); 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; lbl_Hata.Visible = false; 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Session.Add(&quot;R_ARACKONTROLFORM_NAKLIYECIKODU&quot;, edt_NAKLIYECIKODU.Text.Trim()); 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Session.Add(&quot;R_ARACKONTROLFORM_BASTAR&quot;, Convert.ToDateTime(edt_Tarih_Bas.Text.Trim())); 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Session.Add(&quot;R_ARACKONTROLFORM_BITTAR&quot;, Convert.ToDateTime(edt_Tarih_Bit.Text.Trim())); 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Session.Add(&quot;R_ARACKONTROLFORM_NAKLIYECIARACPARKID&quot;, reh_NAKLIYECIARACPARKADI.popupHiddenField.Value); 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ASPxPageControl1.ActiveTabIndex = 1; 
 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; DataView dvEnc = (DataView)SqlDataSource1.Select(DataSourceSelectArguments.Empty); 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; CrystalReportSource1ReportDocument.SetDataSource(dvEnc.Table); 
&nbsp; &nbsp; &nbsp; &nbsp; }

I want to ask one addition question, 
I have built some report with CR in my web site project. But when I publishing it, it wanted the Crystal Reports 9 .NET Redistribution package. I downloaded the file from <a href="http://support.businessobjects.com/communityCS/FilesAndUpdates/cr9netredist.zip.asp" rel="ugc">http://support.businessobjects.com/communityCS/FilesAndUpdates/cr9netredist.zip.asp</a> 
but the cr9netredist.msi file needs 19-digit keycode supplied with the product. But I don't have a product, I just use the VS.Net's Cyrstal Report. Do I have to buy Crystal Reports to install a server? Isn't it free of charge?

Hi mlmcc, 
Thanks for your answer I'll check in a moment. Could you answer my first question? Let me type again;

SOrry, I don't know enough about your tool or ASP to really answer the question.

I'm binding a Crystal Report Source to a SQLDataSource(SqlDataSource1) by a button click like; 
 
&nbsp; &nbsp; DataView dvEnc = (DataView)SqlDataSource1.Select(DataSourceSelectArguments.Empty);

From that poing no problem. The CrystalReportViewer show the report. 
 
But before this operation The Crystal Report runs it's SQL queries and shows wrong data and this slows the pageload. I don't want this happen so I tried to set the datasource(empty one) of CrystalReportSource on Page Init &nbsp;like; 
......Page_Init(..) 
{ 
CrystalReportSource1.ReportDocument.SetDataSource(new DataTable(&quot;EmptyDataTable&quot;)); 
} 
so it's ok no data will be displayed but after I clicked the button, the code in button click work but the CrystalReportViewer don't show any data. 
If necessary, I'm using Visual Studio.Net 2005, Asp.Net with C# and the Crystal Report that comes with 
VS 2005.

Connect Crystal Report to a DataSource

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

Crystal Reports is a business intelligence application from SAP SE. It is used to graphically design data connections and report layouts from a wide range of data sources including Excel spreadsheets, Oracle, SQL Server databases and Access databases, BusinessObjects Enterprise business views, and local file-system information. Report designers can place fields from these sources on the report design surface, and can also deploy them in custom formulas (using either BASIC or Crystal's own syntax), which are then placed on the design surface. Crystal Reports also supports subreports, graphing, and a limited amount of GIS functionality.

Crystal Reports

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications
