Deleting Rows In Datagrid View?
May 22, 2009
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.

I have a client who needs a database to display products.He would like to have the product attributes in the rows headers and new records added to the columns. I have a collection of a class that would contain the products and am binding it as a data source. however all I can get is the attributes to show up in the columns and the records to show up in the rows.

i have datagridview populated with stock code, name and description.And i have docked my datagridview to the bottom. so whenever the form is resized, the bottom section will be occupied completely with the datagridview.But i want to display one extra empty column and multiple empty rows to completely fill in the datagridview.The extra empty column width will be adjusted to the right end side of datagridview.And the no of empty rows will be generated based on how many is required to fill up to the bottomSo that i can create datagridview with full column and row even though some columns or rows are empty.

What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?

I have a table in where I am trying to delete all the rows except for the first. I did manage to come up with the code following:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim dtRemoveRows As DataTable =
[Code]....
In review, this code sort of holds the first row and clears the remaining rows. However, when I exit and reopen the program the rows return. So in other words, I want the rows to get permently deleted. I have searched and cannot find a solution to permenly delete all rows without deleting the first row.

I have the following xml file output below where Deleteme="true" is written when the user clicks on the row's checkbox. I was thinking that once the data is flagged this way I could read the data back in, somehow delete each row specified as above, and then save the data back out.

So I've created a gridview with checkboxes so the user can check as many fields as they want and delete them with the click of a button. It works except that it deletes all selected rows except one, the row with the lowest number. I can't firgure out what logic error is causing this.
Here's the code for the delete button procedure:
Protected
Sub btnDelete_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDelete.Click
Dim count As Integer = 0

How would I delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If I dont delete the successful rows then I will have multiple inserts of the same dataRow and we dont want that! And if I don't move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic I am trying to perform at the bottom of my code, right after I insert into the database.
Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click
'Function declarations
'Object declarations
Dim localOutputServer As SQLServer = Nothing
'Variable declarations (Form)

"Deleting rows from multiple tables in SQL 2005". I need to delete all the rows in the multiple rows where it's the same UserId. My Delete command below:
Delete From tableA
From tableA INNER JOIN
tableB ON tableA.UserId = tableB.UserId INNER JOIN
tableC ON tableA.UserId = tableC.UserId INNER JOIN
tableD ON tableA.UserId = tableD.UserId
Where (tableA.UserId = @UserId) AND (tableB.UserId = @UserId) AND (tableC.UserId = @UserId) AND (tableD.UserId = @UserId)
What is happening from the above query is only the rows from tableA is getting deleted.

I have a datagridview named dgvInventory. Okay when you have data inside your datagridview all you have to do is push the delete button on your keyboard and it automatically deletes the record. However, I want a popup box that says "Are you sure you want to delete this record?", and if yes is clicked then the item will be deleted, if not then the record stays the same.

I am trying to delete rows of an .sdf file using the Database Explorer utility of Visual Basic. When doing so, I get the following error message:No rows were deleted.
A problem occurred attempting to delete row 1.
Error Source: Microsoft.VisualStudio.DataTools. Error Message: The row value(s) updated or deleted either do not make the row unique or they alter multiple rows(48 rows). Correct the errors and attempt to delete the row again or press ESC to cancel the change(s). It is correct that the data in the rows are not unique (and not supposed to be; there is no "error" to correct), but why should this prevent deleting them?
