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. IS there something wrong with the Imports section: Imports System

I have two Datagrids, One grid has all the customers garments on it with style number and contact length. The other grid has the users who have garment issued to them. the style number is in both grids.

.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:
EditBoxSearch.Focus()
' Start out clean.
