In Previous posts I explained many articles relating to crystal reports. Now in this post I will explain how to dynamically display images in crystal reports from database in asp.net.
To implement this concept first we need to design the table in database and give name as Image
Column Name | Data Type | Allow Nulls |
ImageId | Int(set identity property=true) | No |
ImageName | Varchar(50) | Yes |
Image | image | Yes |
After completion of table design insert images data in table by using this post insert images in database using asp.net. After insertion of images in database follow below steps to display images in crystal reports using asp.net.
Now Open visual studio and create new website after that right click on your website and select Add new item in that select Crystal Report and click Add
 |
After that add crystal report then it will prompt Crystal Report Gallery window in that select blank solution and click OK
 |
A blank report will create in our application now click on CrystalReports menu under that select Database under that select Database Expert
 |
After click on Database Expert now Database Expert wizard will open in that select Create New Section >> select OLE DB (ADO) >> in that click on + sign of OLE DB (ADO)
 |
Now select Microsoft OLE DB Provider for SQL Server and click Next (Here we can select SQL Native client option also but sometimes during deployment if servers not contains this native client it will throw error).
 |
Now enter SQL Server name, username, password and required database and click Next
 |
After enter credentials for your required database click Next then click Finish (Here for my database I didn’t set any credentials for that reason I didn’t enter userid and password details don’t get confused).
After click Finish now our database loaded in OLEDB (ADO) section >> select your database >> select dbo >> select required tables
 |
Now open tables in that select required table and move to selected tables section and click OK
 |
After that Database Fields in Field Explorer populated with our required data table now drag and drop the required fields from data table to reports Details section
 |
Now open your Default.aspx page drag and drop CrystalReportViewer control from Reporting tab.
 |
Now select CrystalReportViewer and click on smart tag in right hand side and Choose new Report Source
 |
Whenever we click on New report source one window will open in that select crystal report for Report Source from the available reports in dropdownlist and click OK.
 |
After assign available report to CrystalReportViewer control check your code that would be like this
<%@ Register Assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" Namespace="CrystalDecisions.Web" TagPrefix="CR" %> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Crystal Report Sample</title> </head> <body> <form id="form1" runat="server"> <div> <CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server" AutoDataBind="True" ReportSourceID="CrystalReportSource1" /> <CR:CrystalReportSource ID="CrystalReportSource1" runat="server"> <Report FileName="CrystalReport.rpt"> </Report> </CR:CrystalReportSource> </div> </form> </body> </html> |
Now run your application your report will be like this
 |
In case your report prompt window for UserName and password before we access data in that situation we need to set those details in code behind instead of assign crystal report to CrystalReportViewer control
Drag and drop CrystalReportViewer control click on right side smart tag of your CrystalReportViewer control and uncheck EnableDatabaseLogonPrompt
 |
Our aspx code will be like this
<%@ Register Assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" Namespace="CrystalDecisions.Web" TagPrefix="CR" %> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Crystal Report Sample</title> </head> <body> <form id="form1" runat="server"> <div> <CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server" AutoDataBind="True" ReportSourceID="CrystalReportSource1" /> <CR:CrystalReportSource ID="CrystalReportSource1" runat="server"> <Report FileName="CrystalReport.rpt"> </Report> </CR:CrystalReportSource> </div> </form> </body> </html> |
Now Open your code behind file and set database connection settings and assign reports to the control before that first add following namespaces
using System; using CrystalDecisions.CrystalReports.Engine; |
After add namespaces write the following code in page load event
C# code
protected void Page_Load(object sender, EventArgs e) { ReportDocument reportdocument = new ReportDocument(); reportdocument.Load(Server.MapPath("CrystalReport.rpt")); reportdocument.SetDatabaseLogon("username","password","SureshDasari","MySampleDB"); CrystalReportViewer1.ReportSource = reportdocument; } |
VB.NET Code
Imports CrystalDecisions.CrystalReports.Engine Partial Class Default2 Inherits System.Web.UI.Page Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load Dim reportdocument As New ReportDocument() reportdocument.Load(Server.MapPath("CrystalReport.rpt")) reportdocument.SetDatabaseLogon("", "", "SureshDasari", "MySampleDB") CrystalReportViewer1.ReportSource = reportdocument End Sub End Class |
Now run your application and check your output that would be like this
