Hello,

I have a GridView made with VS 2005 with an edit function.
When I use the edit function and change data and click on update most of the time the data is not updated in the database. There have been situations that I was able to update the data of one row but most of the time this was not possible.
The delete function works fine.

I don´t know what the problem is and I don´t know how to solve it, please help!

Here the code I use:
<%@ Page Language="C#" Debug="true" AutoEventWireup="true" CodeFile="OverzichtProgramma.aspx.cs" Inherits="login_OverzichtProgramma3" %>

Thx for your answer.
This is not the problem. The data is displayed in the GridView, I can delete the data, I have had situations that I could edit the data of one row and not from another row.
But most of the time I can not edit any data.
I don’t understand why!

Solved it.

I changed the sql code of the update query from:

UpdateCommand="UPDATE [Programma] SET [Datum] = ?, [Tijd] = ?, [TeamThuis] = ?, [TeamUit] = ?, [DoelpuntenThuis] = ?, [DoelpuntenUit] = ?, [Opmerkingen] = ?, [ZichtbaarProgramma] = ?, [Oefenwedstrijd] = ? WHERE [ProgrammaID] = ? AND [Datum] = ? AND [Tijd] = ? AND [TeamThuis] = ? AND [TeamUit] = ? AND [DoelpuntenThuis] = ? AND [DoelpuntenUit] = ? AND [Opmerkingen] = ? AND [ZichtbaarProgramma] = ? AND [Oefenwedstrijd] = ?" OldValuesParameterFormatString="original_{0}" ConflictDetection="CompareAllValues">

Into:

UpdateCommand="UPDATE [Programma] SET [Datum] = ?, [Tijd] = ?, [TeamThuis] = ?, [TeamUit] = ?, [DoelpuntenThuis] = ?, [DoelpuntenUit] = ?, [Opmerkingen] = ?, [ZichtbaarProgramma] = ?, [Oefenwedstrijd] = ? WHERE [ProgrammaID] = ? " OldValuesParameterFormatString="original_{0}" ConflictDetection="CompareAllValues">

That solved my problem.
