I can edit the values in the dgv cells manually, add rows, delete rows all without problem and then update the database.My problem is in one form where I want to allow the user to filter the rows in the grid and then enter a value in a textbox and programmatically update all the cells in one column with that valueI can update the rows, and see the changes in the datagridview. When I try and update the database (using UpdateQuery on the underlying TableAdapter of the datagird) only some of thechanged rows are being updated I though it might be related

DataGridView - Update The Change Back To The Bound Table

Dec 17, 2011

I have a DataGridView bound to a data table. I have one column where I permit updates. After I fill the table (at form load), I make an update to this column Then I attempt to update the change back to the bound table. I get the error 'Update requires a valid Updatecommand when passed dataRow collection with modified rows'. I have seen some examples on-line to define, load, and update but since I have the generated datagridview with bindings, shouldn't the update method me a simple 1-liner? [Code]

VS 2008 Updated DataGridView - Sending Updates To DB

Oct 12, 2010

I have code similar to the code below that works in other parts of my program. The reason the code below does not work is because the datatable is made up of data from two separate tables. Does anyone know how to make this work for multiple tables? Can I choose what fields to send back and where to send them? This is what fills my datagridview and it works fine.

Update Dataset Back To Remote Database Via Web Service

Jul 14, 2011

I am connecting to a web service that returns a dataset that I use as a datasource for a windows client datagridview.

Once a user has made changes to the datagridview record(s), how do I get those changes back to the connected dataset and back to the remote database.

I wrote the sql update function in the service:

Code Snippet from web service

<WebMethod()> _
Public Sub Update_equipment_repair(ByVal repair_id As Int64, ByVal date_entered As DateTime, ByVal date_sent_in As DateTime, ByVal date_returned As DateTime, ByVal damage_description As String, ByVal vendor_id As Int64, ByVal repair_description As String)

[Code]....

This displays the records perfectly and I figured out how to delete and insert records via web service.

Determine If There Are Data Changes To Save / Update Back To A Database Table?

Feb 2, 2012

I'm using VB 2010 Express with a local Access DB. I am having trouble determing whether there are changes in a DataGridView to save back to the underlying DB.

The DB has been copied to the project directory and its properties (by selecting it in the Solution Explorer) include Copy to Output Directory: Copy Always, so I know that any changes I make when running a build will disappear on the next build. The problem I'm having is within a run / test session, working with the application.

The Access database has the following connection string, with Application scope:

Provider=Microsoft.Jet.OLEDB.4.0;Data Source="|DataDirectory|Component MI.mdb"

VS 2008 Handle The Updates To The Database?

Oct 1, 2010

what's the best way to handle the updates to the database.For example i have one datagridview that's binded to a datatable (with two fields, id auto incremented and a varchar). The user can do all the operations Insert, Update, Delete.If i insert one row (only the text) and call the update method to save the changes to the database, and after that remove the same row and call the update method the adapter will throw a exception because it didn't update the datatable with the value of the id. So the best way to do this is always calling the fill method after every update?

DataTableAdapter.Update Doesn't Insert New Records In The Linked Access Database

May 20, 2010

I am writing an application that does a number of different things with data downloaded from hardware which is monitoring the power used in my home and produced by my PV Solar array. I have run into a roadblock early on, because I cannot seem to get new data into an Access database that I have linked to my application by means of a DataSet. I have checked the DataAdapter's InsertCommand, DeleteCommand, and UpdateCommand definitions (created by the DataSet Wizard), and they seem to make sense, and nothing is throwing exceptions or otherwise making VB complain, but new rows added to the dataset are not being added to the database.

DB/Reporting :: DataGridView Back To SQL Database Through Stored Procedure

Feb 18, 2009

I have an app written in vb2005 that allows users to search a sql database for a store name. Once a store is selected, it then presents the user with 12 different tabs, each with a DataGridView showing various bits of info about the store. It's a large and convoluted database, so I'm using stored proceedures to pull the data for each tab. Here's a sample of one of the subs that populates the tabs.[code...]

Now, this works just fine to populate the grids on the tabs, and the same code is copied into each of the subs that fill the grids (changing the stored proc, parameter and grid names, of course). The problem I'm having is how to move changes made to the data in the grid back into the database.

I have stored procs that do this (and the procs do work), I just can't seem to figure out how to trigger the stored proc when the user makes a change.

If it matters, there is only a grid on each tab, I did not use a binding source as I am trying to keep an abstraction layer between the data and the app. I did create a dataset, which is how I gain access to the stored procs, but I left the grids unbound and (as seen in my code) bind them at run time.

Visual Basic 2008 Updates Wrong Record In A MS Access 2007 Database?

Mar 7, 2010

i seem to have a problem when i try to update a certain record in an Access 2007 Database. I have a small Access 2007 database with 1 table which has 3 Columns and several records. The 3 columns are RecordNumber (Primary Key and it is autonumber), FirstName(text) and LastName(text). What i am trying to do in VB 2008 is implement a search form which when you find a record you can update it. I do not have any problems with the search, but i cannot seem to edit any other record than the first one. For example i search for John which exists, if that record is the 3rd record when i try to edit it whatever changes i make (for example change that to James), the changes i make are made to the first record and not the current one. I tried a lot of things but nothing works, here is my code:

Sql Filestream - Update A File And Save Changed File Back To Database

Oct 30, 2009

I have implemented the filestream feature of SQL Server 2008 in a VB.Net application. I can insert files, and then retrieve/view them just fine. However, I have huge problems trying to update a file. Eg. The user selects a file from the grid which I execute via process.start. If that file is a .txt file, the user may choose to edit it. In case that happens, I need to save the changed file back to the database. So far I have failed to do that.

What I do, is take the retrieved file, copy it (cause i got some errors about it being used), and then Process.Start it. After that, via .NET filestream, I convert the file to bytes and try to update the record. SQL Profiler and a manual SELECT on the varbinary(max) column tell me that the file is updated properly, but the very next try to retrieve it I get an unchanged file.

After that I also tried to update the file by changing its File-System Version, but the file still wouldn't seem to update. Does Anyone have a code sample of how I can achieve this operation? Like 500 sites on the internet have examples of how to Insert And Retrieve the file, but not a single example on how to update. This is how my second attempt of trying to update the file via the filesystem looks like. The code for inserting/retrieving is very similar and it works properly. [Code]

Update The Dataset Each Time User Updates It?

Aug 27, 2009

Before performing an update, the application must search for that record in the database. Once it's found then it return to the Data access layer. Typicaly when i return rows i return them in a dataset. The i send it to the client to load on to the ListView Constrol or to textbooxes. therefore data was sent from the dataset object, therefore onces the user has made updates to the data, first i must update the dataset.

In the Data access layer i can write method that contains the command object for update DB and bind it with the current Dataset so that each time dataset updates it sychrinizes DB with it. Assume i have a method called update() in teh business layer that calls the updateDB in the DataAccess Layer, how can i call the Update() of the business layer each time the user updates the dataset?
