DataSource Controls :: Handle Coding A Proper DeleteMethod To Assign To ObjectDataSource
Jan 24, 2010
I currently have a gridview which I have populated using the following method:
[Code]....
What I am looking for is advice on how to handle coding a proper DeleteMethod to assign to my ObjectDataSource (via my class file). I have been searching through several forums, websites and other media and have been left a little confused. Everyone seems to have their own method, none of which I have been able to successfully adapt to my own needs. Here is some of the functionality that I am looking for:
1.) Delete item using Gridview's delete button
2.) Delete the record from both the datatable (and Gridview Row) and the database that the table was generated from.
3.) Upon deletion, refresh gridview
This may sound simple to many of you, but I need a little advice as to where to start. Any applicable threads, tutorials etc.

I have a website that basically allows customers to build a cart with an item that can be configured. A user will pick an item, and they'll be prompted to pick the first option they want, they get sent to the second step where they pick their second option, etc. The number of steps and the number of options are variable, as they are defined by the client. Usually the item only has 2-3 steps with 5-10 options. However, in order to make it faster for the customer, if there is only one option available for the given step, it will automatically be chosen and the user will be sent to the next step.
A client decided to set up an item with 10+ steps with only one option for each step. This results in the entire process automatically choosing everything. FireFox doesn't like this, as it gives the error Firefox has detected that the server is redirecting the request for this address in a way that will never complete. I haven't checked IE or Chrome, although it probably gives similar errors).
What's the best way to fix this? Right now the process is basically User picks item user picks option if there is more than one option available. Otherwise the website does step 3 itself. POST to add the option to the cart Redirect to Page.aspx?step=# repeat step 2-4 as many times as necessary
Is there any change I can make to the code or page so that FireFox doesn't think I'm in an endless loop?

I am having trouble with queries because they are not returning the data needed, and I am having trouble figuring out why because I only am testing with 2 records.First I want a query to return all records for one customer as follows:
[Code]....
There are two records with the customerID of 1, but it only returns one,next I try to return only one record, the AccountPrimary or customer_contacts.IsPrimary, but when I add " AND customer_contacts.IsPrimary = 'True' "at the end of my query it then returns both records, but only one IsPrimary = True and the Other = False. Is it backwards? I also tried another method and it returned 30 of the same record and I only have 2

I've created a query in the table adapter for retrieving customer name based on the first letter. The query is executed fine, and the output is the customer name and ID. A Customer BLL accesses this query, and sends the results to an objectdatasource. This control is configured to use this customer-by-letter query. However for some reason, this objectdatasource does not bind the name and ID, but instead all the other fields produced by the main query in the table adapter (i.e. name, address, phone, etc....).
I'm probably not configuring something correctly, but I'm not sure what.
The BLL code:

The .net code:

My Business Logic Layer has AddItem method that add's to Items table in db along with an entry in Balance table.AddItem method uses two TableAdapters Items & Balance. Both these have corresponding Business Objects as Item and Balance.
Here is the AddItem method :

I'm creating an ASP.net website with 3 layers (Presentation, BLL and DAL).
BLL and DAL are 'class library'. DAL has a typed dataset. Presentation refers BLL and BLL refers DAL.
I wanna populate my GridViews with ObjectDataSource, but it only shows me the DAL. Nothing from BLL...
What am I doing wrong?

Consider a fairly complex business object. For the sake of discussion, let's think about a "ClassRoom" object - that will have some attributes which occur once, such as "capacity" and "area". It will also have some repeating attributes - perhaps "desks" which will itself be a collection of desk objects. The desk object will in turn have attributes such as "width" and "height".My example is more complex, but that should show where I am coming from. The business object, as you would expect, exposes methods to get the attributes in and out. There is also logic included to perform the underlying database updates. Of course, the necessary business validation is also in there.
In terms of binding to the ASP page, I will need to bind the attributes of "ClassRoom" to a set of fields on the page (using one method on the object). I will also want to bind the desks collection to a Repeater or GridView (using another method on the object).Presumably, I need to find a way to use a single instance of the ObjectDataSource so that the updates to the two (or more) disparate sets of data can be kept in step. I suspect that if I simply put two data sources on the page, I will get two instances and therefore no correlation between them.This can't be a unique problem, but I'm struggling to find any useful information.

I was woundering if its possible for me to check for accesslevel value from the database using objectdatasouce.... From my coldfusion experience... i could just use an "if statement"
e.g: <cfif> (datasouce.column = x) then
<cfoutput> msg</cfoutput>
</cfif>
Am not so sure about .net.... All i am trying to do is to check for one value on the db and i dont mind puting it on code behind... i just need a way..

I have an objectDataSource which uses my stored procedure GetNotifications
And my GridView is bound to that objectDataSource
the only problem is that my stored procedure requires the variable @UserName and then returns the values for that username, but I do not know how to pass the variable to the objectDataSource, does anyone know the code for this?
I can get userName from HttpContext.Current.User.Identity.Name but how do I pass that to the objectDataSource?

I have an ODS control populating a Telerik grid. The ODS definition is pretty simple. It's set to call a method on a static class that has one parameter (entityID). I set this parameter in the OnSelecting event. When I test this, the world is a happy place and all is fine.
Then, I pass a query string to the page (which sets various unrelated values for the page, we'll say parameters X and Y). The page call's Telerik's radgrid.Rebind() event. When this happens, an error is throw from the ODS saying that the underlying method (the static data procedure) does not support parameters X and Y.
So, why is ODS thinking it should be using any querystring values at all when I have explicitly set the entityID parameter (of type Asp:Parameter)? How do I stop this from happening?
The Html:
[Code]....
The OnSelecting:
[Code]....
I see this odsList_OnSelecting being hit and the inspection of e.InputParameters only contains my expected single entry.

I am trying to update record in GridView. But ObjectDataSource is creating original_{0} and new vlaue object (exactly the same).ObjectDataSource.UpdateMethod is as follows
[Code]....
The paremeters ("original_ProductBO" and "productBO") in the above function are supposed to have different values since I am editing record in GridView and then updating it.I have the checked the query by hard coding parameter values and it works. In the ObjectDataSource_Updating(..) event, I cheked the parameters ("original_ProductBO" and "productBO") , I am getting the same values. Can anyone tell why tow parameters have the same values when I am editing record in GridView Code for the ObjectDataSourec and GridView is attached below

I have a dropdown list that uses an ObjectDataSource. The select method of the ObjectDataSource needs to localize the TextField, so i create a Dictionary<int, string> and use GetLocalResourceObject as such:
[Code]....
In the Local Resource file, there is status0, status1, and status2, all with a value (Deleted, Active, Inactive). The dropdown and object datasource like:
[Code]....
Now, if I use an ObjectDataSource and put the DropDownList's DataSourceID to it, I will get a null reference on the lookup to the GetLocalResourceObject. BUT If I manually set DataSource/DataBind on the dropdown list on Page_Load, it works fine:
[Code]...
OR If I move the status values to a global resource file and use GetGlobalResource instead of GetLocal, it works fine! Why can I not use an ObjectDataSource and LocalResourceObject in this way?

Im using Objectivation as a DAL with GridView !
I would like to link item when i create it with the InsertMethode :
I have this 2 table :
Item ( id, name )
ItemRelation( idrelation, idParentItem, idSonItem)
