Cannot Reference A Dataset Table Using The Strongly Typed Name?

Apr 7, 2012

I cannot figure out for the life of me why I cannot reference a dataset table using the strongly typed name. I created a "news" table in a dataset to write out and read in a simple xml.

If you look at the code below this does not work: 'Dim TableFail As ADataSet.NewsDataTable = ds.NewsDataTable 'Does not work

I can access the table by using an untyped name however: Dim NewsTable As ADataSet.NewsDataTable = ds.Tables("News") What is the proper way of accessing the datasets 'typed' datatables name.

Fields In Binding Source Not Changing When Underlying Access Table Has?

Sep 19, 2009

Re DataGridView Sorry don't really have any code - just a whole project. Basically I changed the underlying Access (accdb) Table by adding a new field, The new field shows up in the DataSources section of the Solution Explorer and in the "Edit DataSet with wizard" page but when I attach the binding source to a datagrid view, the new field is not there. I also created a new bindingsource but still not there.I just noticed I've another table where I changed the names to something more meaningful, and the old names are still there and the data for those fields doesn't display in the DataGridView

Feb 14, 2011

Can you please explain me and/or show some good tutorials how to do it?It seems pretty complicated because visual studio usually does it all for you and that made me stupid and not to do anything about it.Things I don't know to do in code but I know VS does it for me:

[Code]...

I'm sure there is a good tutorial somewhere on the internet. I'm okay with doing it with designer, but now when I have a situation where I can't use MDI container but tabcontrol.Other solution would be to make a MDI container out of tabcontrol. Is it posible or only other form can be MDI container.

Asp.net Mvc - Save Data On A Strongly-typed View When Not All Fields Are Loaded

Dec 9, 2009

Let's say I have an edit view that is strongly-typed to a table called "MyData". The view has multiple tabs, each with several different fields from the table. For performance, the data is only loaded when the tab is viewed, so if you only edit a field on tab 1 and submit the form, the data for tab 2 will not be loaded.

The problem I'm running into is on the submit. I'm doing the typical routine of finding the existing record in the database and updating the passed values:

<AcceptVerbs(HttpVerbs.Post)> _
Function Edit(ByVal data As MyData) As ActionResult
Using dc = New MyDataContext

[Code].....

However, this method doesn't know which tabs were loaded, so if the tab with "desc" on it is not loaded, this method thinks the user blanked out the "desc" field, and sends NULL to the database.

How can I construct this so that only loaded fields are sent to the database, and unloaded fields are ignored?

Add Data To A Typed Dataset?

Jun 25, 2010

I created a dataset in Visual Studio 2010 containing two tables: tblCategories and tblAnswers. tblCategories has two columns: CategoryNumber (AutoNumber and primary key) and CategoryName. tblAnswers has three columns: AnswerNumber (AutoNumber and primary key), Answer, and CategoryNumber. The CategoryNumber columns in each table are related. I have a command button which I want to use to add a record to the CategoryName column in tblCategories with the data typed in a textbox. When I try to access the dataset to add a new row(dataset.tblCategoriesDataTable.NewRow), the NewRow method isn't present. I've done some reading which suggests that I need a TableAdapter, but it seems like that is for connecting to an external file because I have to select a connection. I have no external SQL files or database. I want the user to be able to create a database within my program.

Typed DataSet - InvalidCastException

Sep 12, 2011

I've got a typed dataset. I bind the data with a binding source to a form with arround 200 textboxes, dataedits and so on. Everything works fine with one exception:In my database I have empty DateTimes (DBNull.Value). And when they get bound to a DateEdit-Control, I get the following exceptions:

A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll
A first chance exception of type 'System.Data.StrongTypingException' occurred in myTestDLL.dll

I tried to change the NullValue-Property in the DataSet-Desinger to something else as 'Throw Exception', but it doesn't work for a DateTime. For other types like Integer or String it works fine.I dont know a nice solution (right now I fill the empty dates with some dummy date and make it invisible in the DateEdit-Control, but this is very uncool) and I hope to find some help here.

DB/Reporting :: Strongly Typed Dataset

Apr 20, 2009

Firstly here's the code and i will explain my problem underneath. [code...]

Now as you can see I have a variable that holds a value member of the combo box Products which is the productID of the current product selected. Then it searchers through the products datatable and once its found the correct product or not it stores the answer in slectedproductrow. next I test to see if selected product row has found the product if it has i then see if the product has already been added to the order by seraching the the customer current order datatable if it hasn't it adds the current information to the order by using selected product row.

Now the problem i get is when i add the same product it still adds the information again as currentorderrow comes back as nothing everytime even if the product has been added before but if it was in the table which it should be it should skip that bit and just go to add the current qtys toghther.Also if i go to add a diffrent product it overwrites the the other one. So i can't store the customer order. Its like i can't store more than one row. By the way I have a datagrid and can see the product get over wrriten.
