DataGrid - How To Update Multiple Rows
Feb 27, 2012
I am new to vb.net as well as programming. (Windows application) I have only one data grid, one submit button on form. Datagrid has three columns name, age, salary
User will enter data directly in a row of datagrid. After clicking on save button data will get displayed in grid as well as stored in database.
User also can update data in any row, just by changing cell data of selected row and clicking on save button.
How I can update data in datagrid just by above way? How to guess which row data has changed? If user changes data in multiple rows, how to update multiple rows in this scenario? Can I have to take one extra column in database?

I have the following code in which it supposed to remove rows that have the first column checkboxes checked, but it only removes one row at a time.If you have more than one checkbox checked, you have to click the command button each time to remove the row.It seems that the logic is correct to remove multiple rows if more than one checkbox is checked, but it doesn't work.

Here is a sample piece of my code, the problem that I am have is that I can only selected one record at a time to mail merge, regardless if I select 5 rows from the datagrid. Or I can mail merge the entire datagrid, but I want my users to be able to select the data that they want, whethere it is 1 or 5 rows and be able to mail merge based off the selection. I've been pulling my hair out over this, I know it is something simple that I am missing....Please help...I am working in VB.NET visual studio 2008

We use an ERP program in conjuction with SQL server and lots of tables that keep track of product records customers and all these kinds of stuff. I am building a fairly simple Warehouse Inventory Application that warehouse employees will use to count and inventory stock on hand from products around the warehouse and then check if any quantity errors occur between stock on hand and logistic quantities.I have created a custom Inventory table that I would populate with records like {stock_code, Description, Quantity_remain, quantity_avail}. Those records already exist in 2 different tables in my database. The aim is that I want my program to fetch daily 10 random codes from the stck table, and records about their quantities,bringing together the "columns" that my new custom table has +2 more editable columns: inventory, date, user with a query like this:[code]
As you can imagine my custom table contains the exact same fields as the query suggests + 3 more.I use the the stck table to fetch product info like its code,description, its group_code, categ_code, and then I outer join the stck_x_th that contains records concerning quantities remaining or available asociated with each product code and the "places" those quantities reside in the warehouse.Then, store them in a datagridview control, with only one editable column -inventory- (user and date columns are auto-populated with default values), and then when the user fills out the inventory quantites, I want to save the datagrid "as it is" in my new custom table.I am creating a databound gridview control using one table adapter (which refers to the inventory table). Then I add to my table adapter using "add query" the forementioned query with a fillby method to populate the Datagrid (and therefore my Table in SQL) with the exact same values my query returned from the different tables. But whenever I try to update the table concurrency exceptions raise.It works like a charm if I enter the values in the grid cells manually, without populating the grid control with the new fillby method my self but not if I populate the grid via a query and then hit update.

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 have a datagrid who's ItemsSource is a strongly typed IEnumerable object In this datagrid, I have a checkbox column, a price column, a part name column, and a 'total selling for' column. On checking the checkbox I need to update the total selling for column with the value in the price column. This part I have working, however, how can I get the checkbox to remain checked when this happens?
Private Sub UpdateSellFor(sender As System.Object, e As System.Windows.RoutedEventArgs)
Dim _CB As CheckBox = DirectCast(sender, CheckBox)
Dim _ID As Integer = _CB.Tag
Dim _PP = DirectCast(DG_PartsToSelect.CurrentItem, PartTyping).PartPrice

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.

Our site is developing against a 3rd party API (Wonderware) that returns datasets and datatables from certain calls. The issue we are having with some of the calls is the data returned is more than we want to show to the end users. We are binding the data to a datagrid, and will sometimes get back 20+ columns of data we don't need to show. Is there a way to filter the datatable of columns before binding it to the datagrid? Right now we are using the datagrid to hide the columns, but I think it would be better to strip out the columns of data we don't need before binding to the grid.

For Each row As DataRow In dgrFarms.Rows
Dim sendtroopid As Integer
sendtroopid = row("idColumn")
'Do Something
Next
I've been trying to get a loop through a row in just one column in VB.NET for a while now, and i've done my homework on it too. When i use that code above I get:
Unable to cast object of type 'System.Windows.Forms.DataGridViewRow' to type 'System.Data.DataRow'.
I saw another guide which told me to do:
For Each row As DataGridView In dgrFarms.Rows
sendtroopid = row("idColumn")
'Do Something
Next
But that gives me the error:
Overload resolution failed because no accessible 'Item' accepts this number of arguments.
(That's a blue underline on 'Row("idColumn") )

numbering rows in datagrid. I have a column that should number 1,2,3 so on when adding a new row. When I delete a row, those numbers should re-number still to 1,2,3. So when I delete row 2, the row that's been added as 3 should now number to 2. Then when I add new rows, these should re-number again, and so on..
My code:

I bring data in from an access database using a sql query and then assign the data to a datagrid view. When i try to delete data from the table, it is removed from the datagrid, but the change is not showing up in the actual table.As a second question, is there a way to tag the specific row and send that back to the actual database for deletion? The way i have it set now, i think would delete all instances where digit, day, and office match, instead of just the selected record.
