I was missing binding for the ID needed in that query and was in a label field. Your Eval vs Bind article helped with that. Thanks!

Hello Alex,

Thanks for the article. For me, the call to SqlStreams_OnUpdating rids of PLS-00306 error but it doesn’t update the table. Am I missing anything? I’m not implementing delete, update only…

Thanks,
Goran

how to store .net datatype “guid” into oracle datatype “raw”. and how to retrieve it.
1. i generated guid value and converted it to byte array as
id=guid.newguid().tobytearray();
but when looking the gridview the id is not visible and i cant update or delete data from gridview.
2. if all the id columns used as varchar then guid converted to varchar is stored properly and
displayed in gridview, update and delete is also possible but when i try to use the following
code it gives an error.

MembershipUser user = new Member.GetUser(CreateUserWizard1.Email);

Hi Alexander,

I’m experiencing this exact same problem. I attempted to use your solution with no success. I still get the same error:

ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to ‘MMAR_SP_APPLICATION_UPDATE’
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

Right now, I just want to be able to update a record from the Gridview. Here’s my code.

Default.aspx.cs:

using System;
using System.Data;
using System.Data.Common;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using Oracle.DataAccess.Client;

public partial class _Default : System.Web.UI.Page
{

protected void SqlDataSource1_Updating(object sender, SqlDataSourceCommandEventArgs e)
{
foreach (DbParameter param in e.Command.Parameters)
{
param.ParameterName = param.ParameterName + “_”;
}
}
}

Hello Alex,

I’m trying to add the code to .vb file. I’m not able to retrieve the “OracleType” property. I’ve include the OldDb namespace. Can you post a similar code in VB?

Thanks,
Francis

Comment on Building charts with Dundas Charts and SqlDataSource by alexandershapovalov

Microsoft Charting controls was based on Dundas 4.5 controls (Microsoft bought source code).
But Dundas has now version 6 with a lot of improvements.
Also Dundas charts works well with .NET 2.0, but Microsoft chart controls needs .NET 3.5

If you are a big company, you can afford buying Dundas charts.

Dundas is VERY expensive, if you want a FREE alternative that is based on Dundas, offers almost identical API – try MS Charting control: http://codecorner.galanter.net/2009/06/16/free-alternative-to-dundas-charts-from-microsoft/
