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.
I am developing on application in that i have taken one list box and getting data to it using an object source.up to this stage it is fine.I need to compare these value what i get into list box and need to represent data in to a report viewer ..how to get these values from objectsource.i m new to c# i placing the code.
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)
my query is SELECT a.HD, a.HEAD, a.SH, a.SUBHEAD, a.TRK, a.TRACK, a.TGT, a.TARGET, a.PDC, a.DT_RELEASE, a.STATUS, a.CO FROM V_HIERARCHY1 a

I was looking at the options in Intellisense for the properties used with a parameter for the Object Data Source. There is one that I don't understand how it would be used. explain, or recommend an article, about the DB Type is for and how it would be used?
I have a gridview with all columns read only except one. I want to configure the update method for the object data source to update only one column. The code i have written works when i make all columns editable but fails when i try to make only one column editable.
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 have an insert that uses an object data source with out the direction property set and it works fine. I noticed the direction property though and wondered if I should use it.Should the direction property for the parameters of an object data source be used with a simple CRUD operations?
I'm trying to understand when to use the type property and when to use the dbtype property. I looked online but couldn't find a good article that said when and why.
I created a class library: PRTreatmentReviews. I created a reference for the class library on the website. I checked the property pages and the reference to the class is there. I put objectdatasource on a page and tried to pick up the PRTreatmentReviews class but it's not there? The Class
I am using a list of objects as a datasource and passing the object into a user control. I use the code outlined below
[code]...
When I try to access the object this way, it's null.
Funny thing, I can access the user control and all the control data in the user control, but the object (both in the gridview and passed to the user control) are null.
I'm an experienced PHP programmer that is new to ASP.net (C#). I'm trying to figure out how to do a manual echo of a specific field from an SQL database and was wondering how you do an if condition in case the field would meet certain criteria ?
What I want the script to do is check in the database if a certain condition is activated, then the html page should echo a windows media player object with the source of the video coming from the database itself ( $line[Video], and if the condition isn't active then either don't echo the player or just echo an old video (in the script I'm just printing a message).
I have a Public Sub listed in a class file that I am using to store Select, Update,etc...methods for an Object Datasource. When I attempt to configure the datasource, the Class appears as a business object, but the sub within the class is not available for method selection. (It does not appear in drop down list in wizard.)
The sub exists, so where is a good place for me to start looking for a fix? I have part of the class file listed below:
have a gridview which has a delete linkbutton in 1 column, problem is that the click event for the button is not firing at all, the page does postback but the breakpoint wont execute and jump in the click event at all.
I'm trying to understand how to execute AJAX animation on an asp button that has to execute code on Postback. In other words, I have button with code behind that needs to be excuted, but at the same time want to be able to have one of animation extenders be applied to it. I understand that I need to use the BeginRequest Event, I'm just not sure how, or which javascript commands to use to call the ajax animation so the postback will still occur.
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.
I am using VS 2008 SP1. My also have included CSS Friendly adapter [URL] in my project ( I mentioned this because my GridView Empty data template is not showing when using GridView's CCS Friendly adapter). I have a GridView and a DetailsView. When a record in GridView is selected its details information is shown in the Details View. Type of Data source I am using is ObjectDataSource. My Insert and Update methods works perfectly. It is only the Delete method that is passing null values to the underlying object delete method. My source codes for both the UI, BLL, DAL is shown below
i wanted to retrieve things from the data base and perform mathmatical operations on it then post it to the user, so i was told to use the bullited list and bind it to the object dataSource
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 have the web page that meet the problem. There exists a gridview and filtering. When Select all by using function A, it is OK. when Filter by using function B, it cannot filter and return no rows. When Select all again, it is OK. I have tested that function B can return the corrected filtered rows. But when databind in the web page, it cannot show and no error?
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.
