Using Object Data Source In 4 ReportViewer?
Nov 22, 2010
I think I'm getting mad here...I thought this should be super simple, but I just can't figure out how to do that.This is what I'm trying to do:I want to create an rdlc report using the ReportViewer control in ASP.NET 4 (VS 2010), and, as its datasource, use a class with some properties.I tried everything I can think of, but I just can't figure this out. All the docs I found state that the object should appear in the DataSource pane of the website, but I can't make it appear there.I would like the fields of the class to appear in the report desiger so I can use them - but I can't do that either.Using the designer, I can only define new dataset - I don't want to use dataset, but business objects!So - how can I do that? Do I have to use some kind of DataSource control? How can I make the report designer know about the business object?

I have a reportviewer (Microsoft.ReportViewer.WebForms) control on my page. All my reports use one data source. I want to be able to let my reports run on a different database when started from my UAT enviroment. So the location of the reports is the same, but the data comes from a different db. I cannot seem to find how this is done, is it even possible?
EDIT: They are server reports on SQL Server . I know you can set the dataset programmaticaly but I just want the reports to point to a different db and leave the rest of the report intact.

this is the first time I have tried this so I am probably missing something that is staring me right in the face.
I have an ASP.NET page where the user fills in a request which then emails a PDF rendered from a ReportViewer instance.
It all works fine when I run it locally through the ASP.NET localhost but when I try and run it of the webserver it fails with the following message:
An error has occurred during report processing.Cannot create a connection to data source 'DataSource1'.
I can preview the report via the web based report manager via http://servername/reports which works without any problem and using the report editor in VS2005.
I suspect it is something to do with the credentials but I am at a loss. The data source is set with a username and password but this is saved within the datasource.

I have a reportViewer control and I dynamically setting the report path and dataset in the page load event if it is not a post back. This first report displays without issue. However, when I attempt to change the report path / dataset via the onChange event from a dropdown list I get the following error:
A data source instance has not been supplied for the data source "Summary_DataTable1".
This code works fine and the summary report is displayed the first time the page is loaded.

I've posted the same question in the Object Data Source forum. This is a link to it http://forums.asp.net/t/1554083.aspx. Maybe I should've posted here to begin with. There seemed to be some overlap so I wasn't sure which was the best on to post the question in.
I'm trying to get a better understanding of how I could've designed my app so that the Object Data Source could work with the properties of my business objects. Please read the other post to see how it's currently being done. Sorry for the link to the other page. I didn't want to post a bunch of duplicate information. I would love to get some suggestions for alternative ways of doing this.

Traditionally with an Object Data Source, the wired up class will have its public properties available for binding (i.e. Gridview columns, etc.) which works well. But what if one of my wired up business objects has a property that is an object itself; can I drill down to a property on that object property and still use it?
So in additiona to the traditional:MyBusniessObject.OrderID...I want to use:MyBusniessObject.Customer.NameID
Your 1st response might be to just wire up the 'Customer' class, but I need properties both on 'MyBusinessObject'and 'Customer'. I do not think this can be done, as the ODS will not display properties on an object instance property. I have tried manually typing in the drilled down value as well, but that wasn't a success either.

I am writting a website using .net in some of my pages I need to use datagrid for showing some datas and for binding my data to datagrid I use object datasource something like below :
//this is
public class userData
{
private long userid = 0;
private string username = null;[code]....
and then in my apsx file I put an objectdatasource and bind the select statement to the GetUsersAmount() and then bind obejctdatasource to my datagrid but I think the way I've chosen is not efficient I just want to hear about your way of doing such these things.

I set up a DAL layer in a dll. This had a couple poorly named methods such as GetData(), which is the default name offered up in the tableAdapter wizard. I also added a few other methods for various reasons, all with better names. I then built the dll and referenced it in an ASP project. On one page, I added an ObjectDataSource, and set it to that tableAdapter (which isn't what I wanted to do, but that's a different story). Under the Select tab, I see the GetData and the other methods. Under the Update tab I see a variety of Update methods. Under the Insert and Delete tabs....I see the same methods as I saw under the Update tab. The Insert and Delete methods that exist for the tableAdapter were not available.
I figured that I did something wrong, and I didn't like that GetData name, so I went back to the dll and changed some things around (I think I added an Insert and Delete method, but by now I can't remember, except to say that I wasn't all that surprised not to see those two methods the first time). I also changed the GetData name to something else, then rebuilt the dll.
Since that time, I have yet to be able to change what shows up in the Object Data Source configuration. The Select adamantly insists on the GetData method, which no longer exists under that name, while the other three tabs all show a variety of Update methods, but neither Insert nor Delete. I noticed that just adding a reference didn't have any impact until the ASP project was built, which moved the dll to the bin folder where it needs to be for the Object Data Source configuration wizard to see it. Therefore, I deleted the dll from the bin folder, then rebuilt. I've also removed the reference, deleted the dll from the bin folder, rebuilt, added the reference, rebuilt again to get the dll back into the bin folder, and anything else I can think of. It still seems to be retaining the original schema from the tableadapter without ever updating to the new name for the GetData. Since that hasn't updated, the rest doesn't surprise me.

I have an object data source that is being used by an rdlc report, and the object data source uses a filter that is built from session variables passed to the page.
The report displays correctly, with the filter applied; however, I want to mark each of the rows as "printed" in a bit field in the database table.
In the table adapter, I have the following Update command that is used by the object data source:
UPDATE dbo.WorkOrder
SET boolWorkOrderPrinted = 'True'
WHERE (WorkOrderID = @Original_WorkOrderID)
And in the Page Load event, I run:
ObjectDataSource1.Update();
However, no records are updated.

I used bind all GridViews, DetailViews etc. on my page using an ObjectDataSource (unless it wasn't possible to do so). Recently, I've started binding all my contols programatically. I find this a lot cleaner and easier, though some may disagree. Binding with a ObjectDataSource obviously has it advantages and disadvantages, as does doing it programatically.Say I bind a GridView programatically (e.g. GridView1.DataSource = SomeList), when I change page on the GridView, I have to also code this. Each time the page changes I have to call GridView1.DataSource = SomeList again. Obviously with a ObjectDataSource I don't need to do this. I normally stick my SomeList object into the ViewState so when I change page I don't need to hit the database each and every time.
My question is: Is this how the ObjectDataSource works? Does it store it's data in the ViewState and not hit the database again unless you call the .Select method? I like to try and get the best performance out of my applications and hit the database as few times as possible but I don't really like the idea of storing a huge list in the ViewState. Is there a better way of doing this? Is caching per user a good idea (or possible)? Shall I just hit the database everytime instead of storing my huge list in the ViewState? Is it sometimes better to hit the database than to use ViewState?

I am playing about just now trying to teach myself a little bit about the entity framework. I have a Gridview data bound to a Entity Date Source using the Entity Framework. If I select certain items in that list I then wish to redirect another page and populate another gridview with just the items selected (but with more detail, different includes/navigation properties)
This is probably the most simple thing but I have spent 2 hours banging my head on the wall trying to get this to work. Essentially I have a continue button which when clicked should identify all the UIDs (a column in the gridview) of the rows and allow me to subset to just these rows and pass them to another page to be rebound to another datagrid

I have extended GridView in order to have consistent look & feel, paging and sorting. However, when the page is first time loaded, the select method is getting called twice. It works fine when i move between pages in pagination.
Note, i am using Asp.net 2.0.

I'm working on a site where we want to include a pie chart on a page. Right now I'm working on implementing that through Reporting Services (RDLC file) with an object data source.The SelectMethod of my object data source is a method that returns a list of business objects; lets say a List<Alpha> and Alpha has a sub object Beta with a Name property. In my report definition I have set the Category groups to be: =Fields!Beta.Value.Name this means that Alpha.Beta.Name are my pie slices. I got the following error:
An error has occurred during report processing. The Group expression for the rouping 'chart1_CategoryGroup1' contains an error: Object variable or With block variable not set.I was able to confirm this is because Beta is nullable and was able to fix the issue by updating the object Alpha to return a new Beta() if the Beta property is null. This solution is not ideal though because there are other places in my code where I need Beta to be null if it doesn't have a value yet.Is there a way to update the report definition to accept a null property as valid? Ideally I would like to specify the value as "Not Set" if Beta is null.

I populate a DetailsView from an ObjectDataSource that is coded in a class - meaning that the ods Select, Update, Insert and Delete are class methods. The selected record is set to come from a GridView.SelectedValue.
My problem is that when the page loads the code crashes. I am pretty sure I know why: the DetailsView is pulling from a class object and instead of using the existing class object it instansiates a new one which is empty.
Here is the details view code:
[Code]....
Here is the odsDetailsView_1:
[Code]....
As you can see from the code the odsDetailsView gets it's information from a class object "Match". The detailsview is not controlled by any code behind.

i made a small n-tier webapplication, a DATA project with my business objects a DA project with my datacces logic and a GUI project woth my website. For the CRUD operations on my main tables I use a lot of listviews, that works fine but when data grows its slows down.I used already used optimal paging & shared collection's to preventing database acces if data is already loaded en that helps alot.But I see when a user select the EDIT command the select of my listview is performed what is not needed, also when the user than select cancel the select is again called , is this normal behavior or do I made a mistake in program logic somewhere because this behavior is slowing my application down.
