View 1 RepliesADO.NET :: Strongly Typed Dataset Exception Handling?
Sep 28, 2010I'm currently working on a 3-tier ASP.NET application (UI, BLL & DAL). The DAL uses a strongly typed dataset that I've created with the VS Dataset Wizard. My question is, what is the best way to handle exceptions originating from the BLL and DAL classes. I googled a bit and it seems that the most commonly used practice is to create DALException and BLLException classes and throw your own message. Is this the way forward? how this can be done for an automatically generated DAL? What are the best practices?
View 1 RepliesADO.NET :: Return A Single Row From A Database As A Strongly Typed Object?
Nov 10, 2010I have a products table whereby I want to return a single row via a product id and use it as a data object.
I have used a .xsd dataset and a product class where I return a dataset and add the values into the product object that I created but I don't like having to write code like
"Product[0].ProductDescription" to get the product description. Is there a way of returning is straight as an object rather than a dataset?
Dynamic Connection String For Strongly Typed Dataset
Jan 20, 2010I have an asp.net nTier application. The data access layer is a strongly typed DataSet consisting of multiple DataTables with DataAdapters. When the user logs in, they choose which database to connect to (from a table in the membership database). I need to pass the selected connection string into the DataSet object which will remain the same for that users until they log in again. I'm thinking that the answer might be to create a partial class of the DataSet object where I can pass the connection string into the constructor. Im not sure how to go about this though.

View 9 RepliesDataSource Controls :: Difference Between Typed Dataset And Data Source Controls?
Nov 1, 2010I'm new to this community and got newbie question, briefly in data access in asp.net what is the difference between accessing dataset using typed Dataset and using data sources controls like SQL data source control ...? As I noticed that using data source controls is much easier, but it allows only one data access method i.e. only one query... am I right with that....
View 1 RepliesDataSource Controls :: Not Able To Create A New Table Adapter?
Jan 11, 2010I have a strange issue. I have a XSD file where I have created some TableAdapters. When I have reopened the XSD file it seems like I am not able to create a new table adapter since all the options which will come when I right click on the XSD file are disabled. I have cross verified whether I am on debugging mode but...I was not..(I am not even able to drag and drop an adapter from the left toolbox menu either)I am getting the same issue when I open the same XSD file on somebody else machine but I am able to create TableAdaperts in other XSDs.Can somebody suggest me a solution for this
View 5 RepliesStrongly-typed Or Weakly-typed Binding In Codebehind In Front End?
Feb 23, 2010So my question is more in relation to what people consider to be the best practice and why:
I've been dropping literals into pages and repeaters and binding them in code behind for a while. Is this considered bad practice?
ie:
ASPX Page:
<asp: Literal id="litTextToInsert" runat="Server" />
Code Behind:
litTextToInsert.Text = objData.MyText;
OR (repeater):
[code]....
I personally dont like doing this as i find it makes it harder for me to know if someone changed the field name, or mis typed it during development - the other way you won't know until the page loads.
With the strongly typed version if something changes in your DAL etc the build will break - letting me know I've messed up.
Why do so many people appear to use weakly typed code in ASP.Net (in examples, MVC, etc)?
Am i missing something?
DataSource Controls :: Setting A Typed DataSet (xsd) Connectionstring Dynamically?
May 25, 2010I'm trying to set up a simple content management system for two different sites, which are both stored on the same server (my own, not hosting, if it matters:)).
Both sites are basically the same, built upon a similar (but seperate) xsd (Typed DataSet) file, and read data from different databases using the tableadapters in the xsds.
Obviously, i have the same xsd setup in my management system application that need to hook up to the relevant database (after user authentication) and use the tableadapters to access the data and allow the forms in the management system to modify the data.
When i had a single site, the connection string was stored in the web.config file and after logging in to the management system, all forms could access the database.
Now i have two site and i need to setup the connection string in the xsd dynamically after user validation based on the relevant site to edit.
My question is, how do i set the xsd's connection string dynamically (after user logs in, the function returns the specific connectionstring and stores it in a Session variable)
MVC Strongly Typed Versus Dynamically Typed Views
Nov 25, 2010Given the benefits of using strongly typed views to eliminate typed errors and the use of lambda expressions why would one use a dynamically typed view? When I use them I don't feel as safe as with strongly typed views. Am I missing something? Is there a special use for them?

DataSource Controls :: Reading Typed DataSet TableAdapter Row From ObjectDataSource.ObjectDataSource_Selected?
Mar 25, 2011I fill a GridView from a ObjectDataSource that points to a Typed DataSet.
I need to read a couple of row columns from the object data source that IS NOT part of the Gridview.
So far, I have found out that ObjectDataSource.ObjectDataSource_Selected is the right event to do this.
Examples on the internet refers to e.OutputParameters, but that appears to be empy even though rows are returned.
e.ReturnValue seem to contain a type related to the row type, but I cannot interpret this either.
Forms Data Controls :: Binding Formview To Strongly Typed DataTable In Session Object?
Sep 29, 2010Okay, here's something that I could easily do the hard way and manually wire up each form element and save it to a datatable in memory, but there has to be a more efficient way to do it.
Here's what I have:
1. A strongly typed datatable and tableadapter in a XSD name Orders
2. A formview control which currently is connected to an ODS connected to the Orders tableadapter, this makes it easy to wire up the databindings for each form field in design view
I would like to:
- bind the the formview to an instance of the strongly typed datatable, and then save the dt to a session object without interacting with the actual database
- load forms on subsequent pages from the dt in session
- ultimately save the dt info to an actual database table on the third page
I've read some solutions where a custom class is created, but to me this seems like almost as much work as wiring up the form field to the table columns manually in code.

View 1 RepliesForms Data Controls :: Using Multiple Tables Within A Single DataSet And Single SqlDataSource?
May 19, 2010I have a stored procedure that returns 3 tables within the single recordset it returns. If I set a SqlDataSource to get data from this procedure, it works, but it only returns the first table. I want to have a GridView display the data from the 2nd or 3rd table using a SqlDataSource, but I can't figure out how to specify a particular table.
While there are some posts discussing this out there, I can't get a definitive answer about whether or not this is even possible (?). In a worst-case scenario, I can create another SP that only returns the 3rd table - but that creates a little maintenance headache that I would prefer to avoid.
