View 1 RepliesUpdate Data From Data Set And Table Adapter
Oct 6, 2010I have a windows form program that pulls data from a sql server. That same data is being read from a ASP.NET website that sets properties for the site. The SQL server has 3 tables: tblWebPage, tblObjects, tblProperties. and 6 views for the 6 web page: vWebPage01, vWebPage02, vWebPage03..ect. When the program loads you see buttons for each web page on the site. When the user clicks on the Home Page it loads this data: [code]Now, the problem lies in updating vWebPage02, vWebPage03, ect.. I assume with the same data I can copy my form with the code and change the form name and the data set to build and update. So that's just what I did changed the form name where needed and changed "vWebPage01" to "vWebPage02".When I tested the program My "vWebPage01" form it built and updated no problem. when I went to test "vWebPage02" it built the dataset and table adapter fine but it did not update at all.

Aug 12, 2010i'm using vb 2008 and local database sql server compact 3.5 to build a application.the problem is that i can't insert a new data to the database from the app. i'm wrote the query right at dataset and using table adapter. but when i call the query, it succeed but the data don't exist at database.why when i add data, it's not working. actually when i run it, it says that adding process is success, no error, and it shows at the datagrid. but when i look at database. the data that i add is not there.and in tableadapter, i also make sortData, seachData query, i can use both of them perfectly when i run the app.so, i really confuse why is the insert query didn't work.
View 2 RepliesData Adapter Command Objects?
Jun 22, 2011I'm confused with this piece of code listed below. This code calls the update method of the dataadapter object to save the changes made to the dataSETback to the database itself. What I don't understand about this code is that it creates an update command(cmdUpdate), insert command (cmdInsert) and delete command (cmdDelete). My understanding is that the update method saves the changes back to the database. So I don't understand why the author creates these additional commands.

Updating Data From A Table Adapter
Apr 18, 2006Honestly I do not understand why I need to write code to update a databse and why it stores it localy. I'd simply rather the system update the individual row after it is scrolled off of.
In either case since I guess I can't do that.
Here is some code in a button on a form

VS 2008 - SQL Data Adapter Commands Parameters
Feb 22, 2010I have a very large table, and I have a sql data adapter to fill a data table. The user is able to change some values, then saves the changes, at this point i just call the adapter update method (I use the sql command builder to get all the commands of the adapter). What I need it's to make some changes to 4 parameters in the update command, before calling the update command, but I don't see how to do this? Before the update itself, I don't have any values, if I set the parameters (I saw the number of the parameters in the debug mode), before the update, that doesn't do anything, I think they get override in the update method...

View 3 RepliesVS 2008 Data Adapter RowState Remaining Unchanged?
May 2, 2009I've got lots of textboxes bound to a Dataset. When I make changes to a textbox with the mouse/keyboard the rowstate becomes changed - and when I do the .EndEdit and update the row it goes to the DB.
I've got some textboxes that get changed in code. When this happens the rowstate remains UNCHANGED. Updates to the DB never occur.If the textbox is changed in code and I also change another textbox in the UI then both changes make it to the DB.
I've verified that the "in-code" changed field in the dataset is actually changed - but the ROWSTATE is still printing as UNCHANGED.Here I'm showing that field 29 has changed to "blank" - but the RowState still is UNCHANGED. Why would changes to the .Text property of a bound control does programatically not change the row state?
Seems a google for this does uncover issues like this - but nothing that's helped me fix it so far - here's one link I can't make sense of[URL]..
Selecting Specific Data To Fill A Datasource Table Adapter?

My problem, is that this program will have multiple users, and I don't other users to be able to see each others data. So the problem with the above statement is that it fills the table with ALL the data in the datasource. How can I make it only display data that is for a specific user?Here's the code that is used to fill the tableadapter:

View 16 RepliesConcurrency - Restore A Dataset To The Previous State Before Updating The Database With A Data Adapter?
Dec 10, 2009How do you restore a dataset to the previous state before updating the database with a data adapter? I have a concurrency update problem that I believe to be caused by this. The update fails during the update and a rollback command is issued using a SQLTransaction object. However, now the rowstates of the rows that did not have errors have been changed to unchanged. So this record is no longer availible to be inserted into the database. When I updated the value that could not be null and then test the second update which runs just as the first does then I get a concurrency error. The update code is below:
