I want to let others to delete selected row in the following datagrid view and I have written it like this. Now when I select a row and press the delete button I can remove the selected row
but it will not update the database which meant it will not deleting the above row.
I have bound my datagrid view using databinding.

This is such a basic question, I'm almost embarassed to ask it. How do I loop through seleted rows in a DataGridView and remove the rows?I've tried this, but it doesn't work. After one row is removed, the index is all screwed up.
With a DataGridView bound to a bindingsource, which is filled by da.fill(ds) . How do I go about deleting selected rows when the UserDeletingRow event is fired? I've used the following code in the event:
Dim dsEmplTran As New DataSet daEmplTran.Fill(dsEmplTran) dsEmplTran.Tables(0).Rows(dgvEmplTran.SelectedRows(0).Index).Delete() Dim cb As New SqlCommandBuilder(daEmplTran)
How can I delete a row from an SQL database based on what item is selected in a listbox?
The listbox is populated by the database, I bound it to the data source.
I tried this code but get an error:vb
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim myCriteria As String = CStr(ListBox1.SelectedItem) Dim deleteStr As String deleteStr = "DELETE customText WHERE userText = 'myCriteria' " End Sub

I have an ini File which I use as an "index" of jar files. The Jars are declared in it like: Name of the jar=c:Path So when my application starts, the ini file gets loaded in a list view. I have a delete button, with which I want to delete the jars from the list view and the ini file. It must be possible to delete multi choiced jar references. so I thought to do it with for each, so that every selected item get searched in the ini and deleted. The Error is, that the String (is correct, I tested it with a messagebox) get analysed - Unknown escape sequence R (The error is between the ** **)

I have a form with a treeview and a listview. The treeview lists the folders on your system and listview shows the files in the selected folder, similar to windows explorer. I have a delete button for deleting files.
[code]...
When deleting multiple files a confirmation message box pops up for each file selected. I would like to have it come up once and ask 'Are you sure you want to send these 'x' files to the recycle bin?' where 'x' is the number of files selected.
I wonder if it's possible to assign BindingNavigator.PositonItem with a datagridview selected row?
I have looked through msdn and it looks like it ain't - am i wright ?
All in all i've got a problem with delete item - it can only delete an item with number that's in PositionItem, while I'd like to delete current clicked row

I have a List of an object, set to DataSource of a BindingSource, set to DataSource of a DataGridView. Then I added a DataGridViewButtonColumn which I want a click to remove that record from the collection. So I simply call collection. RemoveAt (e.rowIndex) from the DataGridView CellClick event. However this produces an IndexOutOfRange Exception; "1 does not have a value"..
So is happening here? I have maybe a vague idea, but would like to understand exactly which events are failing etc.. and what do i need to do to perform this action properly?
EDIT: This seems not to happen if I use a BindingList.. But when using a List, I get this problem..
