I have a grid view with two columns...one column has a no. like (123) and a check box....which user can checked or unchecked......all I need to do is that I need to disable the man handling of that check box......rather I would like to see a seperate grid view with the same no. of rows as of the first and in this gridview I may allow to type in or scan the no. and if this scanned or typed number matches any no. in the first gridview number then the corresponding check box should be checked/unchecked.

I have to find the best way to do this using LINQ. I need to summarize an amount in a iTransaction table by
Account (e.g. 12345) and add that amount to an same Account ( e.g12345) if it exists in a iAccount table . Here is the code which syntax checks ok and tested ok up to the .submitChanges statement (i.e. I stopped and didn't allow the submit.
Following is the LINQ code. (1) Is that a good way to do this. OR should I try the INTERCEPT.
(2) How is the best way to insert a new record/row in the iAccounts table if it DOES NOT exist in the iAccount Table.

Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
The above error occurs with gridview control , when used with template field columns with item template / and edit templates etc.
updating a row within gridview, at the time of loadiong it loads perfectly fined, but when tried to modify an existing row within gridview control, then it produces the error. Make sure the grid view control has to be a child control which manages the child table info with in a master form. to reproduce the above problem the grid view must be loading the child records info of a master within the masterform, meaning both master data and gridview data all to be managed in one single form.
I had to replace gridview control with datagrid and then it worked perfectly fine. I wasted almost 4 days of my time., there is no way we could figure out the problem. here is the full info of the problem.

I've got a GridView on my page which has some bound controls, one of which is a label (to display total price):
[Code]....
However this value is not being passed to my page. All I see is '£' symbol, no price which makes me think Viewstate["youpay"] is empty? I have enabled viewstate on the Page and Control tags.

I am creating a gridview dynamically in a custom control and adding it to a Panel. I set the EnableViewState = true. The problem is that on a page postback the GridView does not seem to retain its values. If I add a GridView through the UI then the viewstate is preserved. The problem seems to occur when it is put dynamically only.

I have a DataTable with about 10,000 rows in it.
I would like to store this data once for aspx page. When the user selects different options in the page, data is further selected from the already stored DataTable.
I tried using the ViewState, but as soon as the data grows beyond 100 rows, performance degrades.

I have a checkbox column in a Gridview that is added in the aspx and the other columns are added in the code behind. The checkbox is a choice to print the record or not. When the print button is pushed the page posts back and the checkboxes are gone.
I have read that you have to re-add the checkboxes on postback, but where do you do that and how do you retain the viewstate values - checked/not checked? I have tried everywhere - PreInit, PreLoad, PreRender... I can't get the viewstate values to appear anywhere. The checkboxes can be added just about anywhere but the vaules are set to "unchecked" by default... no values ever come back no matter where I re-add them.

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.

i am new at the ViewState and i am looking to see what values are stored within it. I know how to loop through an array to check for a value but i do not know how to go about doing that for a ViewState("test") property.Let's say i have added "bob, tom, Jim" to a ViewState called ViewState("test"). I would like to be able to see if "tom" was in the ViewState("test"). If not then add it but if it exists already then skip it.

My datasource is an ado data table that I have convert to a new data table so that each row in the original table is now a column with 1 row in my new table. I then bind the new datatable and create dynamic template fields with a text box where I bind the values. My problem is, when I try and retrieve the values changed by the user in the rowcommand event, the template columns no longer exists.
Does anyone know how i can retrieve these values? I've read over and over that you have to rebind the grid on each postback when you use dynamic templates, but I'm not sure how to do that and retrieve the values entered in the text boxes on the client side.

I'm developing a custom webcontrol from GridView.
I've run into this bizarre situation wherein I get the below error if I set page size other than 5 in the page using this control.
"Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request."
This GridView is a hierarchial type. I add a new GridView below each row in the webcontrol overriding OnRowDataBound.
If I set pagesize as 5 the paging works properly.

I need a bit of help with a scenario. I am working on a web application that requires huge amounts of data to be Added, Deleted, and Updated. The data entry forms are divided into logical groups through Multiviews. All the information is saved when the mighty Finish button is pressed. The current setup (previous developer) does not allow me to use transactions. Therefore, if I am to save a new Courier to the database, I need to add his/her Distance and Rate info. In addition, I need to add his/her Banned Areas info (Area Name, Post Code).This is where it gets interesting. Obviously, the DistamceAndRate table and the BannedArea table in my SQL Server will have the CourierID as a foreign key. Since I'm going to save the Courier as well as the Rates and Areas info in one go, I cannot have the newly created CourierID before. Therefore, I cannot bind my Grids for Distance + Rates and Banned Areas directly to database.What I am doing is creating two DataTables and managing them in Viewstate through properties as follow:
[Code]....
So, on page load, the DataTables are initialized with a blank schema. Here are the attempted CRUD implementations (Distance and Rate only):
[Code]....
I am having issues when I am canceling a new entry and when I am editing a new entry. In addition, for Distance and Rates, Rate is acting as unique (cannot be repeated) and attempting to control that is also giving me a headache. I end up creating blank rows.And here's the ASPX cut-out:
[Code]....
Hope to get an answer soon.Also, off-topic, I'm using LINQ here. In order to save a Courier and his/her extra details, I first save his/her address to DB. Then I take the ID of the address and save the courier. now the courier ID is avaliable and i start filling extra tables related with the courier table. If something goes wrong, I have to manually delete created rows. LINQ uses transaction internally but only until a SubmitChanges() call. I'm forced to save each entity so I keep calling SubmitChanges().I tried manual transaction but after saving the address inside a transaction, the Address.OID (Address table's mapped prime-key) had a 0. attempting to use this newly added address while saving Courier in the same transaction threw an exception. If there is a way to get the primary key for entities created in a transaction that is yet to be commited, please mention that'll as well.

I've got all of my ASP.NET requests wrapped in a Session and a Transaction that gets commited only at the very end of the request. At some point during execution of the request, I would like to insert an object and make it visible to other potential threads - i.e. split the insertion into a new transaction, commit that transaction, and move on. The reason is that the request in question hits an API that then chain hits another one of my pages (near-synchronously) to let me know that it processed, and thus double submits a transaction record, because the original request had not yet finished, and thus not committed the transaction record.
So I've tried wrapping the insertion code with a new SessionScope, TransactionScope(TransactionMode.New), combination of both, flushing everything manually, etc. However, when I call Refresh on the object I'm still getting the old object state. Here's some code sample for what I'm seeing:
Post outsidePost = Post.Find(id); // status of this post is Status.Old
using (TransactionScope transaction = new TransactionScope(TransactionMode.New))
{
Post p = Post.Find(id);
p.Status = Status.New; // new status set here
p.Update();
SessionScope.Current.Flush();
transaction.Flush();
transaction.VoteCommit();
}
outsidePost.Refresh();
// refresh doesn't get the new status, status is still Status.Old
