Unable To Delete One Or More Rows In DataGridView
Mar 13, 2012
I am displaying a Master-Detail tables in a DataGridView. The Master has only one table and the Detail also has only table. Both tables have primary keys. I would like to give the user the capability to delete one or more rows from the Master or Detail when they click on 'Delete' buttons. I am using VB.Net 2010, MS Framework 4.0 and Win 7. The database is Oracle 10g. I have written the following code but it doesn't seem to work. I keep getting 'Number of records updated: 0'.
Here is the code to delete from Job table (Master) when the user clicks on btnDelJob:
Private Sub btnDelJob_Click(sender As Object, e As System.EventArgs) Handles btnDelJob.Click
Dim i As Integer
Try
Dim response As DialogResult = MessageBox.Show("Are you sure you want to delete these rows?", "Delete row?", MessageBoxButtons.YesNo, _
[Code] .....

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 dont 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

My problem is probably ignorance as to how the DGV works, anyway, the problem.I have a bound datagridview which is used to collect user input. Data for 3 of the 7 fields is entered by looping through the rows and progmatically entering common data anfter a 'Save' Button is pressed:
For I = 0 To DG1.RowCount - 2DG1.Rows(I).Cells(4).Value = TextBox1.Text 'OperatorDG1.Rows(I).Cells(5).Value = TextBox2.Text 'DateDG1.Rows(I).Cells(6).Value = TextBox3.Text 'Time NextDG1.Update Prior to this loop I delete the last unused row if its not a new row:
DG1.CurrentCell = DG1.Item(0, DG1.RowCount - 2)If DG1.CurrentCell.Value.ToString = "" ThenDG1.Rows.RemoveAt(DG1.RowCount - 2)DG1.Update()End If
At this point the DGV looks the way it should...All fields completed correctly and no un used ro except for the new row.
After saving :Me.ItemTableTableAdapter.Update(Me.StockMoveDataSet.ItemTable)The 'Operator', 'Date', and 'Time' are not saved to the database for the first row only I have tried EndEdit, Update, refocussing the currentcell/row all to no avail.

Can anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.
