How to create a graph on a web page including the data taken from SQl table

Here are two common options come to mind:
+ Use the Graphics object to generate the image on the fly.
+ Use a third party component available out there to implement what you want.

thanks a lot.

You mean from code behind? Send the dimensions as paramaeters to the function just as you do with the URL.

b { font-weight: normal; }

can u tell me how to call this function from code behind?
function openPopup(strOpen)
{
//alert(strOpen);
open(strOpen, "Info", "status=1, width=300, height=400, top=100, left=300");
}
i want to call it in page load section
|

You can not call that function from code behind. The ASP.NET code is run on the server, and that function is Javascript and only works once it's loaded in the browser. By then the server code is already completed.

b { font-weight: normal; }

Make sure that you use relative addresses in your links. If you specify an absolute address (e.g. http://www.mysite.com/mypage.aspx), it won't contain the session id.

Hi
Assume we have a datalist that is populated from database and every item in it has an associated ID and we would place a check box under each item . Show me the technique of iterating through items in the DataList and finding out if any of them are selected and getting its associated ID.
have a problem with this method.
I have a button that when clicked ,in its click event, I iterate through the datalist but I find all check boxes unchecked even when they are selected.why this happens?
refer me to a useful article about this or tell me yourself.

Hi
I am trying to display a Crystal Report developed using MySQL database and ASP.NET 2.0 (VS.NET 2005), and for some reason when I pass the database login information to the report it does not accept them (still shows a db login screen). Here is the code:
[CODE]
Dim cnString = "DRIVER={MySQL ODBC 3.51 Driver};SERVER=servername;DATABASE=dbname;UID=user name;PASSWORD=password;OPTION=3"
Dim cn As New OdbcConnection(cnString)
cn.Open()
Dim MyReport As New CrystalDecisions.CrystalReports.Engine.ReportDocum ent
MyReport.Load("C:\Inetpub\wwwroot\Report1.rpt")
MyReport.SetDataSource(cnString)
MyReport.SetDatabaseLogon("username", "password")
MyReport.SetParameterValue("parameter1", "1001")
CrystalReportViewer1.ReportSource = MyReport
CrystalReportViewer1.DataBind()
cn.Close()
[/CODE]
I have one Crystal Report Viewer and one Crystal Report Source objects on the form. The Crystal Report Source is set to "Report1.rpt" and the Viewer's source is set to that as well. When I run it, I get a parameter field request followed by a server login information request.
The actual Report properties are:
Database DLL: crdb_odbc.dll
DSN: NameOfDSNSource
UseDSNProperties: False
UserID: databaseUserName
I have even tried this:
[CODE]
Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared
Imports System.IO
Imports MySql.Data.MySqlClient
' Class Name etc here ...
Dim conn As New MySqlConnection
conn = New MySqlConnection("Server=servername; Database=dbname; User ID=dbuser; Password=dbpass; charset=utf8;")
conn.Open()
Dim MyReport As New CrystalDecisions.CrystalReports.Engine.ReportDocum ent
MyReport.Load("C:\Inetpub\wwwroot\Report1.rpt")
MyReport.SetDataSource("Server=servername; Database=dbname; User ID=dbuser; Password=dbpass; charset=utf8;")
MyReport.SetParameterValue("parameter1", "1001")
CrystalReportViewer1.ReportSource = MyReport
CrystalReportViewer1.DataBind()
[/CODE]
But so far no luck. Does anyone know what the problem is with it? Any help would be appreciated.
Thank You
