Delete Multiple Rows In Datagridview?
Apr 26, 2010
If I wanted to delete multiple rows in my datagridview how should I go about doing it? The info inside the rows are all in generic lists. How can I retrieve the selected generic list row, and how would I delete it from my .csv file?

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
'Function declarations

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, _

I have created a bound DataGridView and then added an unbound checkbox (name=select) for selecting multiple rows. The problem I'm having is the row doesn't actually get selected when I set .selected to true which I'm doing in the CellValueChanged event. When I trace it the code is properly executed but the row is not highlighted when the checkbox is checked and consequently not selected in the grid.There is no mouse or keyboard and the input device is a USB button panel which we built.
Public Sub dataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As DataGridViewCellEventArgs) Handles DGV_Categories.CellValueChanged
If DGV_Categories.Columns(e.ColumnIndex).Name = "Select" Then

In this form, I have a 'Remove Selected' button which will remove all selected rows in DataGridView. And another 'Remove All' button which will remove all rows in DataGridView regardless of rows selected or not.

I have a Windows application form. Directly on the form I have a lable ("Customer Names"), a ComboBox (pulling actually names from a database) , and a Buton to add a customer to the database if i choose. Additionally I have ControlTab(3 tabs) that has "fields" and its own Buttons to insert data into a different table. The first 2 tabs have textBoxes, which are completely functional, but the 3rd tab has a "DataGridView"
