Updateing DataSet From DataTableAdapter

Aug 4, 2011

I have an access database that I would like to add a row to. Contents of the row are entered through text boxes. The problem I am running into is the data is not being saved to the the dataset. It only saves to the TableAdapter and is visible in DataGridView.[code]

MDB Database Updateing From Two Forms?

Jun 22, 2010

I'm new to databases under vb.net although I've used them extensivley under VB6.I have a main form with a DataGridView on it. Thats connected to the following bits- _TWC_Viewer_SubmissionsDataSet, ViewerDataBindingSource, ViewerDataTableAdapterm and TableAdapterManager. All this was etup by the VB wizard. The database table is named ViewerData.This all does it job very nicely.

Secondly, I have another form which is setup so that when you click on a main form record line it opens up the second form for in depth record editing.The second form is a bunch of text boxes ect to represent each field.This form has its own set of database bits- _TWC_Viewer_SubmissionsDataSet,ViewerDataBindingSource, ViewerDataTableAdapter, TableAdapterManager and ViewerDataBindingNavigator.This form also works fine and does what it should.The problem is with a 3rd area. Its all in code and creates its own temporary dataset. After its done its job, its saves its results back into the database which also works ok.However, the changes in teh database are not being reflected back to the controls on either form. If I kill the app and restart it then the updates are in the database so its just a form updating problem.

Updateing Text Box Contents With Masterpage?

Jan 8, 2009

I have a webpage that is used to modify information in a database. The information is properly pulled from the database and properly displayed in their appropriate text boxes. The problem arises when i change the information and try to resubmit it to be saved. Unfortunately it never takes my edited information and reverts back to the original value that was loaded when the page was loaded.

All of the code has been tested out side of the masterpage and it is working properly so i am under the impression that it has something to do with the use of the masterpage. If my understanding is correct i cannot just do something like me.txtName.text to address an object in the content pages. So here is a snippet of the code and the portion that i am assuming has a problem.

[Code]...

The code shows the two methods that i have used to try and use findcontrol to access the text boxes. Both methods seem to locate the textboxes but once I pass the values to linksUpd it reverts back to the value that was originally loaded into the page and discards all of my changes.

Unique Datatableadapter Has Been Identified In Dataset1.xsd For Each Datatable

Feb 12, 2009

I am working in vb2008.TableAdapterManagers are a new feature in vs 2008 and I would like to understand how to use them properly.I have about 30 tables in my database that are unique to themselves and donot link to other tables.I have created a dataset.xsd in my solution and dragged in my database tables of interest.A unique datatableadapter has been identified in the dataset1.xsd for each datatable.Rather than using the identified datatableadapter for each datatable operation, should I be using the dataadaptermanager for each unique table?

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.

IDE :: Dataset Code Behind Datatable.ColumnChanging Event Firing / But Dataset.HasChanges Property Not True

Jan 28, 2010

I have code running in the Datatable.ColumnChanging event in my dataset. This dataset underlies a form and conventional drag/drop controls are in place for data entry.when the event triggers and runs, I am running code in the form that checks the dataset.HasChanges property. It is showing False. But this is immediately after the ColumnChanging event has been triggered.Okay, I see by others posts and MSDN that .HasChanges will only be true after moving off the row with the changed column. I have also noted lots of discussion about the advanced binding property of DataSourceUpdate Mode, but that does not address this issue.I guess I can do this by checking the state of the row for the binding source. Just seems odd that the event behind the dataset can be triggered and that does not change the dataset.HasChanges property.

System.Data.Common.DbDataAdapter.Fill(DataSet DataSet)

May 14, 2012

I have tried everything I can to get beyond this error which shows below as <<<<< error here. It is trying to fill a dataset from a data adapter. If I change the SELECT statement to just SELECT * FROM xTable I get the correct number of records in each table. But anytime I try with a more complex statement I get the error message shown below which indicates System.Data.Common.DbDataAdapter.Fill(DataSet dataSet. I've completely erased all data and entered a new set of test data so I know there is no problem with relationships. Each table has primary key which is foreign key in other table.

.net - Combine Multiple Dataset Columns To One Dataset?

May 19, 2010

I have multiple datasets that I would like to combine into one. There is a common ID field that can be associated to each row. Calling Merge on the dataset will add additional rows to the dataset, but I would like to combine the additional columns. There are too many fields to do this in one query and therefore would make it unmanageable. Each individual query would be able to handle ordering to ensure the data is placed in the correct row.

For Example lets say I have two queries resulting in two datasets:

SELECT ID, colA, colB
SELECT colC, colD

The resulting dataset would look like

ID colA colB colC colD
1 a b c d
2 e f g h

Repointing A Report Dataset To A Test Dataset

Feb 18, 2011

ok, I've finally got my test database issues sorted out, however now I need to actually modify my existing report to add the two new fields from my test database. I have made a copy of the report so that I am not modifying the original. I have deleted the two old fields and now want to add my two new fields in there. In the Field explorer window, I see an object called "dataset1" and when I expand it, it is using a view that includes fields from the table that I added my two new fields to.

The problem I see here is that I have gone in and modified the view to include these two new fields in my test database - but again, they are not showing up as selectable fields here. I am just assuming that "dataset1" is somehow pointing to the live database again and that I need to change the datasource location.In my solution explorer, I see an object called "dataset1.xsd" but the properties of that do not tell me much about where it is actually pointing to...

C# - .NET Dataset Design - Have A Dataset For Each Table?

Jul 23, 2010

I have some concern about designing Datasets. I was told that it would be good to have a dataset for each table for maintenance purpose. Because frequent change in database tables is expected, having one dataset including every tables would be pain to make the corresponding change in the application.

Q. is it good approach to have a dataset for each table ( I would end up having 30~40 datasets for each db table using Stored procedure) ?

I have a separate project for commonly used datasets. each project include "dataset project" as a reference, and use it by including needed dataset into Forms, classes, etc.

Q. Does this approach makes the whole system to be slower? If I have a set of datasets as a separate project, it would be beneficial, since It will be easier to make a change (I only need to make modification in one place)

Datatype Of A Dataset - Filling A Dataset

Feb 26, 2010

I am having difficulties with Filling a dataset. It seems to be automatically assigning a datatype to the column based off of the first field of data it finds in that column. The column sometimes contains an integer, but it may also contain letters and numbers. If the first field is an integer, it says the fields in the column that contain a letter are DBNull. I'd like for the entire dataset to be formatted as a string/text type since I do not know what the values will be that I'm importing 100% of the time. How do I tell the dataset to expect a certain datatype for all columns and rows i'm going to import?

Declaring Variables With New DataSet Vs DataSet?

Apr 16, 2010

What is the impact of creating variables using:

Dim ds as New DataSet
ds = GetActualData()

where GetActualData() also creates a New DataSet and returns it? Does the original empty DataSet that was 'New'ed just get left in the Heap?

What if this kind of code was in many places? Would that affect the ASP.NET process and cause it to recycle sooner?

MS Access - Dataset - How To Reset A Dataset

Jun 9, 2011

I have a form that has 1 text box and has 2 queries that locate the data. One is by customer ID and the other is by customer last name. They both work but when the code works and the user enters a customer ID and the query locates it then enters a customer last name it also locates it. If the user enters the same customer id again the query seems to fail. This is why I'm sure I need to add some kind of code to reset the Dataset.

Here's the code in the load sub procedure:
