DB/Reporting :: Edit Multiple Rows At Once?
Apr 22, 2008
In my datagrid, i added a checkbox column, and what i want to do is be able to change the value of one column (in as many rows that are selected) to a certain value. Like from a combo box is it possible to have a combobox in a messagebox? or do you have to create a new form?

I am looking for a howto or someone expert in ADO.NET who can explain me how to properly solve the following scenario:I have two datatables in a dataset:
ParentTable (ParentID, Name) for user data ChildTable (ParentID, ActivityID, ...) for schedule data
Tables are linked together at the database level by ParentID which is an Identity column in ParentTable.
Both tables are data bound to a separate DataGridView on the GUI. There supposed to be a "1 parent/N children" relationship between the tables, meaning if I create a new entry in the ParentTable (a new user) I get a clean DataGrid in the child grid to type schedule data for the user. So I setup two DataAdapters for each table to fill their result into a DataSet. I also set up a DataRelation object and assign it to the DataSet to link the two tables by their ParentID columns. Also when I add a row into the ChildTable via DataGrid I use SetParentRow to set the parent row.

I am using Datagridview to show some table data from database. It is working but its appearance is not what i am looking for. Is there a way to edit columns and rows manually ?
This is a list of what i want to do :
1. First of all i want to change column captions. because they are like "Fld_name" etc.
2. There is a column that shows date. I want to write a code for it ( convert date type )
3. I want to add a button at the end of each row and write a code for it ( show detail about that record )

I have an application where I would like to allow the user to change one field in a datatable but leave the other ones uneditable. I am using a datagridview to do this but I can only make the whole table editable or not. The result should be an order form where you have a determined product and should only be able to change the number of items.

I have a DataGridView bound to a non-SQL Server database.I need to allow users to edit existing records but under certain circumstances I need to intercept the edit and instead of committing and updating the dataset I need to delete the edited record and re-add it as a new record.I have tried using every event I can think of to do this but haven't managed to get it right. [code] This almost works but sometimes completely messes up and re-adds rows twice and all kinds of other bad side effects.

I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts

I am attempting to fill a form with multiple rows from an access table based off of a parameterized query. My query works fine but I don't want to return one row at a time, I want to return all rows that match my query in multiple text boxes. I know that I can use a datagrid view to accomplish this, but I would prefer the look of a textboxes on a form. I have read through many books and searched the internet forums but think I may just not know what to search for as nothing has worked yet. Can anyone point me in the right direction. So far I have tried setting the text box value to the row().item(), creating a different dataset for each row, and even setting variables for the results of the query to then be passed to the text boxes. Since none of this work, I don't really have any starting code to post. If I could just get a starting point I could work from there, so don't feel the need to code anything for me, just set me in the right direction.

I have a question regarding the dataset usage in Reporting Services. I have a stored procedure which returns multiple select statements (result tables), and I created a Dataset in Reporting Services 2005 with this stored procedure. The problem is that I can not reference the second or third result table, and I can only use the first select statement fields. Is this the limitation on Reporting Services Dataset or is there a way to use multiple table results in one dataset?

I'm using Visual Basic 2005 and I have created a program to display, edit, and create insurance records. Right now I am using an access database and it is hosted locally. What I want to be able to do is host it on our server here at our office and have the program installed on every computer on the network.
My connection string at the moment looks like this:

I am trying to summarize a datatable based on a primary column and then add certain columns. For example this table
col-1 col-2 col-3
1 AA 2
2 BB

This simply doesn't do anything becuase it thinks the target table doesn't have a primary key.

When referring to a list or group in .net, generally, it starts with 0 as the first item, but concerning the starting place in an Access table the first row is considered 1. Is this correct and, thus, represented in the code below?

If dtOrderEntry.Rows.Count > 0 Then

I am making a game and decided to add a high score section. I currently have this code setup to insert and read from the database, I set the insert code to a bottom just for testing purposes.[code]There are three columns in the database rank, score and name. I set the rank to auto number so the database would assign the player rank automatically, how would I go about inserting the score into the relevant place inside the database and moving the other scores to their new relevant places?

1) I have a checkbox field in a datagrid, and when you check the box, it highlights the entire current row, and when you check the next one, it stops highlighting the first one and highlights the one I just clicked on. What I would like to know is how can I keep all the rows with a checkbox highlighted?
2) I have a column in my datagrid that I have changed to combobox and I did two things both gives me this error, first I inserted the values for the combobox in the collection. Second, I connected to one of the tables with a binding source and has one of the columns as the options (advisors).
Each student has a different advisor so the field gets set to the correct advisor each time but the problem I am getting is when I scroll (doesn't happen for a little while) I get an error so i put in this sub to handle it and the error message box says: Error Happened Formatting, Display.

MessageBox.Show("Error happened " _

Using Visual Basic in Visual Studio 2008, I have created a Windows form with multiple tabs and questions. Each question has an associated drop-down listbox that the user will eventually click on to enter his or her response. My client has now informed me that she wants to change the standard responses in each response box. There are well over 100 drop-down listboxes, all with the same items, and they all must be changed.
I originally inputted the items using design view. Would someone please tell me if it's possible to edit all of these boxes in the design view simultaneously? When I control + click on more than one box, the Edit Items option that is normally available disappears. Is there a way to do it in code in a manner that would save back into design view?

I have a datagridview view that looks like this SeriaId | ProductName | Model | Manufatcurer The datagridview starts with all cells empty.(or is there something else i can use instead of grid view?) The user will enter data in each of the columns. The number of rows the user enters changes(is unknown). The user could enter only one product or five products.
So, once the user has entered all the products he has to enter, i want that when he clicks a button, all products will be saved to the database. A check should also be performed for correct details, and if its possible, the use of stored procedures would be better

I have a table with following data Fields:
OID, Product, Condition, QTY DATA:
1, Product A, NEW, 60
2, Product A, B, 60
3, Product A, C, 40
4, Product B, NEW, 30
5, Product B, C, 20
I want to write my procedure so that when I execute it, it will return a table as such.
Product Name, NEW, B, C
Product A, 60, 60, 40
Product B, 30, 0, 20 SELECT PRODUCT,(CASE WHEN CONDITION LIKE 'NEW' THEN QTY END) AS NEW, (CASE WHEN CONDITION LIKE 'B' THEN QTY END) AS B, (CASE WHEN CONDITION LIKE 'C' THEN QTY END) AS C
FROM TEST
I got to the point where it will show different quantities in corresponding column but I was unable to merge them into single row.
