I validate a DataGridView with the CellValidating-eventhandler.That works fine. However, I want to avoid validating when the user presses the Cancel button. In the sequence validation occurs before the event CancelButton.Clicked.

function Delete()
{
confirm('Delete this user');

I have a BindingNavigator and combobox tied to the same BindingSource. I want to allow the user to confirm a delete after hitting the delete button of the navigator. It appears that the row gets marked for deletion after my BindingNavigatorDeleteItem_Click event handler is processed. Is there no way to cancel the delete activity from within the delete click event? If not, then it becomes necessary to store a delete flag and catch another event to RejectChanges.
When a user wants to delete a row in a DGV, they are asked if they are sure they want to do it.
how do I go about stopping the row from being deleted should they say no?

I have a datagridview that has three columns. All three fields are unique fields in the Access table that the datagridview reads from in order to make sure that an entire record is unique. I have a form where a user can add a new record. Upon opening the form, two of the three fields have data automatically entered, leaving one field for the user to enter information. The field that the user needs to enter information in is put in edit mode. The problem I am having is that I have a Cancel button if the user does not want to enter a new record and wants to close the form. I tried using the following line of code to remove the current record that has information in two of the three fields before closing the form:
PriceHistoryBindingSource.RemoveCurrent()
Ive got a datagridview, which the user can put in to 'edit' mode by double clicking. If they then make changes but click to another row, I want to msg asking if they are sure they want to discard then changes. If they say No I want to stop the selection change from being made.

I'm trying to delete a number of records in a table from the last and forward. My idea is to use sql like this: delete top " & variable & " * from table where ID = something It gives me a general sytax error. Is it at all possible? Fuga. Edit: I also have the order by statement there. I just forgot to put it in the question.
View 5 RepliesI was trying to use the System.Threading.Timer to run a function every 250ms - but I'm finding it difficult to cancel the timer from within the callback function. I can't seem to find a reference to "this" (js has this - it's so nice). At any rate - how could I start a callback running 250ms from now - without a timer - and then if I want to continue it again do another start for 250ms.

I'm new to VB and using a datagridview for the first time. I've spent the last 2-3 days trying to get row deletion to work and can't do it. I've tried every piece of code I can find on the internets, and none of them are doing it.I have the selection mode set for full row, with a delete button on the form. Clicking it will delete the row from the DGV, but the changes are not going back to the database. Here is the code I'm using right now in my delete button event handler:

The row disappears from the DGV, but not from the database. I've gone back and started from scratch a few times now
how to go about the code for a button to delete the row in a datagridview. i have rows of data in there with a button at the end of the row. the difficulty im having is assigning the values in the row to delete it from the data grid and then update the database to remove the entry.i've tried this but it doesnt work? i'm sure there will be some short statement to do it but dont know what it is.

I have a VB 2008 program over the Northwind DB customer table.It uses LINQ to add, delete and edit records.
So I load everything into a datatable/dataset first.The Add and Delete occurs when the buttons are clicked on a binding navigator. The edit occurs when a cell is changed, and that row is clicked off. I've set the Customer ID field as the primary key in the DT. I then bind everything together with a binding mavigator.
So far so good, Adding & Editing works nicely the DGV & customer table . [code]...
