I was able to get the formview bound to the objectdatasource, it works great for the first record, but when i select the next record it gives me error below is all my code, if there is something else that i need to post .

I am using a GridView with an ObjectDataSource bound to a DataTable. I am using the GridView for displaying a report, NO editing is being done, just read only, however, I am sorting and paging. I need to turn off ViewState for the GridView to improve performance. After turning off the ViewState I start getting the error messages for both paging and sorting:The GridView 'gridView' fired event Sorting which wasn't handled.This is fine I just need to know how to implement the Sorting and Paging events correctly to leveage the ObjectDataSource. I would preffer not to remove the ObjectDataSource from use, especially if there is a way I can manually wire up the datasource correctly to continue to use the GridView as I had been when ViewState was on.Any help on getting the datasource wired up or a solution for handling the events in the context of the datasource would be great.
View 1 RepliesI'm having a problem with a FormView control that I have bound to an ObjectDataSource. The problem is that the FormView control is not automatically filled in with the public properties of the object linked by an ObjectDataSource control when I select refresh schema. Everything compiles and I can add fields manually, but there are a lot of properties in the class and I do not want to deal with adding all the fields by hand. It's not the end of the world of course if I have to add them manually, but I'm bothered more by the fact that it doesn't act the other formviews.
Has anyone ever experienced a problem like this? I have other objectdatasource controls with other formviews that properly refresh their schemas. I noticed that in the objectdatasource control that is giving me problems, the DataObjectTypeName field is not automatically set as it is in the others. However, after adding it manually it still doesn't refresh the schema. I'm using Visual Studio 2010. Defined in .aspx page:

I'd like to implement a custom paging template for my formview that displays numeric paging as well as next/previous buttons. The pre-defined templates only appear to have numeric first last as an option. Can anyone recommend a good article that covers this?
View 2 RepliesI have read many online articles showing how to implement custom paging with stored procedure and objectdatasource control. So I know the benefits of custom paging on large result sets and I know how to implement it.
In my application, I have a stored procedure which is using ROW_NUMBER and taking parameters such as startIndex, pageSize etc. I also have method in my DAL who call this stored procedure and on my page I have GridView and ObjectDataSource control and they are calling DAL methods and everything is working perfectly fine.
Now I want to implement GridView paging without ObjectDataSource control by calling the DAL methods manually. I dont want to use ObjectDataSource control because I need manual access to the DataTable my DAL methods return which I think I dont have if I use ObjectDataSource control.
how to implement paging without ObjectDataSource control
I am using ObjectDataSource controll to bind gridview and using custom paging. Everything working fine but the problem arises when last page contains only one record and i try to delete it-- gridview disappear.
Below is ObjectDataSource declaration..It is working fine..only problem is with deleting from last
page which is containing only single record.
<asp:ObjectDataSource ID="ODS1" runat="server"
TypeName="MyClass"
SelectCountMethod="GetDataCount"
SelectMethod="BindData"
DeleteMethod="DeleteData"
EnablePaging="true"

ObjectDataSource - Custom Gridview Paging and Sorting?
View 2 RepliesI'm using a FormView which has odsMain as the datasource. I am also using a dropdownlist which is being populated with objectdatasource odsddl.
I'd like to set the selectedvalue of the dropdownlist with the value contained in odsMain (the current record value for it). Is there any way this can be done?
I have an ObjectDataSource giving me data similar to: OrderNumber OrderDate OrderValue OrderItems The first three are simple data types and the last has multiple occurrences of another class: OrderLineNumber OrderItem OrderQuantity The ObjectDataSource will only contain one row (which might make things simpler). So, there will be one OrderNumber, OrderDate and OrderValue; and then several occurrences of OrderItems (each containing OrderLineNumber, OrderItem and OrderQuantity).
I am displaying OrderNumber, OrderDate and OrderValue in the FormView - that work's fine, as expected. I have placed a GridView within the FormView and am failing miserably to get it to bind to OrderItems. I have tried the obvious things like specifying "odsWhatever.OrderItems" as the DataSourceID for the GridView, but to no avail.
I have a FormView bound to an ObjectDataSource that is bound to a business logic object. The business logic object has a Readonly field called "Id". When I try to update the formview, I get the following error message: The 'Id' property on the type specified by the DataObjectTypeName property in ObjectDataSource 'ObjectDataSourceNewsArticle' is readonly and its value cannot be set. How do I get the ObjectDataSource or the FormView to recognise that the id field is readonly, and to not try to update it?
View 3 Repliesi am building my objectdatasource dynmically when certain buttons are clicked on the page.. and with that the gridview is being displayed with the results of the objectdatasource that was built.
So my gridview code looks like this:

How can i enable sorting and paging if the datasource is being built on button click event?
If I disable the ViewState on a ListView, the events raised by it are no longer ired. OnPagePropertiesChanging is the ListView event I've always used in combination with the DataPager to update the ListView to the correct page once a DataPager item is clicked, but since its not being fired, I'm wondering if there are any other options. My ListView is currently in an UpdatePanel, and I'm caching the results that the ListView is being bound to. I could rebind the cached results on the PageLoad, but I can't think of a good way to determine if the PageLoad is being accessed because the DataPager was clicked, or for some other reason, so this doesn't seem like a good idea
View 2 RepliesBasically as the title of this thread states, I have a FormView that has a GridView inside it and my ObjectDataSource that populates this grid cannot access the Grid.
The Control Id needs to be the name of the Grid I want to access, however through the 'wizard' the Control parameter drop down cannot 'see' the grid I need, only the FormView that is in.
I have tried numerous ways to get round this and am struggling now..
I've tried the following...
ControlID="FormView.GridView1"
ControlID="FormView.FindControl("GridView1")
ControlID="<%= GetNameOfGrid %>"
and numerous other attempts that also failed that I now cant remember...
I'm still begginer in ASP.net and wonder whether is it possible to assing a keyboard shortcut to next (previous) page command. For example: after press PageUp on keyboard - the next record is shown in FormView, after press PageDown - previous record?
View 2 RepliesI am having a formview control with paging enabled. It's a simple page used for viewing pictures. (It's from the personal web site starter kit with some modification)

I would like the formview to pass not only the pageindex value but also the Next or previous picture's unique ID called in my case PictureID?
I have problem getting values from viewstate in GetTopThemes.
<asp:ObjectDataSource
ID="sourceGetTopThemes"
runat="server"

when the page is not Posted back, I saved all values in the viewstate.
I have a FormView and a GridView connected to the same datasource inside of a MultiView where one view is for the grid and the other for the form. The GridView has selection enabled and when the user selects a record in the GridView I make sure that the same record is selected in the FormView.mv.ActiveViewIndex = vIndexForm; // causes the MultiView to change views from the grid to the form
fv.PageIndex = gv.SelectedIndex + (gv.PageIndex * gv.PageSize); // causes the FormView to use the same selected record as the GridView
This should cause a PageIndexChanged event (it doesn't), so I called by event handler explicitly. In the event handler I change the mode to FormViewMode.Edit. This should cause a ModeChanged event (again it doesn't), so again I called it explicitly.Finally in the ModeChanged event I get the DataItem for the FormView so that I can update some special fields that require some special formatting, however fv.DataItem is null which means I can't do any special formatting. At this point the FormView shows and the regular fields are fine. If I now hit the Cancel button the FormView fires the ChangedMode event at which point I changed the MultiView's ActiveViewIndex back to the view with the grid. The grid displayes just fine, but if I do a select of a row within the GridView again I get the "Failed to load viewstate" error.I can only assume that I'm either doing something in the wrong order or at the wrong time and it's tripping me up.
I have a listview that I'm binding programmatically. I am trying to add a simple datapager but the paging is not working. it is because I am binding programmatically.

Why is the auto paging not working for me? Is that because it only works for BoundField? Mine is mostly
templatefield. Other than auto paging, everything else works fine. I have at least 20 rows, so once I
specify AllowPaging="ture" and PageSize="5", it should give 5 rows a page for 4-5 pages, right?

I published my application into server. Some reason gridview paging is not working when i open the application from the server.
Note: When I ran the application at my local system using VS-2008 it's working fine.
Can Someone explain why this doesn't work here, when it works in another formview?
