After the SubmitChanges call, the Text field in data2 wasn't changed. According to the NerdDinner sample, I supposedly can just write to my data object and then call SubmitChanges.

I got a gridview to display the data from the database properly but when I go edit. it give me an error. I searched and change ConflictDetection=CompareAllValues to OverwriteChanges
The error goes away. However the database is still doesn't update. Does anyone had to tweak the gridview function to make it works. Maybe I did something wrong.
I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.

i am working on Linq,as we know to use any table in linq we have to drag and drop it on our datacontext's Designer File,and at run time we got its value,till here no any problem,main point is if any changes in respective data source's schema has made ,then on datacontext we will not get that changes,for it we have to change this datacontext manually by by again drag and drop,it will not happen implicitly when this changes has been made on the data source. how i solve this problem so that datacontext change implicitly without any over head using .net 3.5.

I have a page that binds data from DB to a DetailsView.I want to use the auto-generated Update command.
Everything went OK, and also updating was successful, but if I remove any field that I don't want to have chance to update, then the Update command doesn't update! the old values retain!
I mean: if all of the fields are present in the detailsView, the update will be OK, otherwise, the update will NOT update any thing.I've tried to mark the fields that I don't want to view as "Visible = 'false'" but with no good results!

I have a vb.net page that has an optional parameter. If a user enters data for that field, and clicks save, it saves fine via the stored procedure. HOWEVER, if the user changes their mind, and wants to erase the data they entered, they go to the text field, and delete the characters, and click save, but no matter what, the stored procedure will not save the fact that they erased the data (it won't set it back to NULL). If the user enters a space, the stored procedure will save the space, and if they enter different data, it will save the other data. I can't figure out how to get it back to letting them set it to Null? I think this is because it's an optional parameter, and the stored proc is used by several forms (Some of those forms do not include this parameter), but this form utilizes that optional paramater.
Here's my stored procedure...

I have an update / insert statements. If the user selects the checkbox IsPrestigeFeatured, I want that row to be set to 1 and I want all other rows to be set to 0. E.g. so there is only one row which is "Is prestige Featured"
My update statement:
ALTER PROCEDURE dbo.Update_Property
@propertyId int,
@propertyTypeId int,
@Name ntext,
@Price int,
@DescriptionResultsExcerpt text,
@Description ntext,
@Characteristics ntext,
@IsRenovation int,
@IsCharacter int,
@IsPrestige int,
@IsHomepageFeatured int,
@IsPrestigeFeatured int,
@CityId int,
@DepartmentId int,
@CommuneId int
As
UPDATE Property
SET Name = @Name, PropertyTypeID = @propertyTypeId, Price = @Price,
DescriptionResultsExcerpt = @DescriptionResultsExcerpt,
Description = @Description, Characteristics = @Characteristics,
IsRenovation = @IsRenovation, IsCharacter = @IsCharacter,

I have a linq DataSource and a Grid in my htnl and I want to access the DataContext from code behind. Now in the past when I do evrything in code behind I just use...
DataContextName db = new DataContextName();
and I have my reference.
Now I can still do that and it works fine it just seems odd to be making a second class object when there is one that is made from the linq DataSource in the html. But I can't figure out how to get a reference to the DataContext that is created from my html code.
I have a gridview and when i click on the edit button i will get the modalpopup window which is having a popup window i want to update the data in that details view and refresh the data into gridview also.

I searched a lot of threads but still couldn't get my problem fixed. I have to update the "regform" table with two fields: session_ and session2. These two fields are inside the detailview edititem template which bounded to dropdown list drpsession1, drpsession2 separately. I wanted to pass the update parameters to the update sql UPDATE dbo.regform SET session_=@session_, session2=@session2 where id=@id
the @session_ is bounded to a drpsession1 and @session2 is bounded to drpsession2. I used
ControlID="ctl00$ContentPlaceHolder1$DetailsView1$drpsession1" to access the dropdown list within the detailview, but still couldn't do the updates. What's wrong with my code? Do I have to use the code behind to specify the update parameters? and How to do it? TIA.

i want to build a datagrid bound to a datatable with several columns. One column has only a dropdownlist with the number of the rows in the datatable.
Here a samplescreenshot:

I know how to bind the columns to a grid and its no problem to create such a dropdown list with the content for me, too. But i dont know how to sort the complete datatabl after changing one value of one dropdown listbox.
So, how can i resort the values of a datatable column based on a given value and the datarow id?

I am using asp.net 3.5 c#. I am trying to do this:
In one page, a user can insert some stuff (name, phone .. etc) to the database. And then the user should be able to see the rows he added as a list automatically in a datalist (or other control). As he inserts rows, it appears in the datalist.
I tried to use update panel and inside it datalist, with a button as a trigger but it did n't work with me!
I've got a single table, with project information and schedule information. To make the data easier to present, I created a tab control with two panels (a detailsview in each). The first tab is for project info, the second tab is for schedule info (again, all fields in the same table). The problem is, if i change info in both tabs, and then hit the update button, only the data from one tab is added to the table. I think this problem is simple to fix, and boils down to the way I have the page organized, but I can't quite figure it out.
I've boiled my code down to the following conceptualized structure:
[code]....
When you click the update button, you return to the listview, but with only the information from your current tab saved. How can I get it to update from both detailsviews?
