On a data grid view there is a blank row with a (*) in it that allows the user to insert a new row of data.Is there a way to put focus on that row using code even though the data grid view has many rows already loaded in it?
View 1 RepliesIf a user clicks the blank row at the bottom of a DataGridView and moves focus away from the DataGridView, the row click in now is in a state that indicates a change is made to that row.
Is it possible to tell the DataGridView to un-mark this row as being changed?
Is it possible to reset this row when focus is off the DataGridView?
We are using the following event handler to alert the user if the Invoiced On is left blank:
Private Sub dataGridViewPayments_CellValidating(ByVal sender As Object, _
ByVal e As DataGridViewCellValidatingEventArgs) _
Handles DataGridViewPayments.CellValidating
[Code].....
Looks like we need a way to stop this from executing if the user simply clicks in the grid then clicks somewhere else in the form.
Datagridview . in cell validated handler and I have the column,row for the cell that I just checked on. If the cell contents are bad, I want to force the cell value to be blank and focus back on that particular cell and try again.The code i've tried simply moves to the next cell in the grid instead of staying where I want it to be. Surely there is a command to focus and put the 'cursor' back in a particular cell.Some sample code I'm working with:
MsgBox(
"Invalid Job#, Correct or DIE!")

View 2 Repliesfollowing is the code at button event which copy data from one DGV (dgvAccesList) to another DGV (dgvProbReport) and its working properly. Its paste data to 3rd and 4th column of destination DGV.But the problem is that, if at source DGV first column and second column have data..lets say up to 2 rows..then its copied data starting from 3rd row..for the 3rd and 4th column..which is incorrect..its should be always start with first row of third and fourth column.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
For Each dgvRow As DataGridViewRow In dgvAccesList.SelectedRows
Dim dgvNewRow As New DataGridViewRow

Basically I would like to have an sql statement which selects all the bookings from a table in microsoft access callled tblBookings where a certain date (selected by a datetimepicker) selected in vb.net.

This is my code:

I've inherited a form that has a DataGridView that is bound to a dataadapter and it is connected to a binding source. Within the DataGridView is a combo box that is bound to its own bindingsource which basically just calls a stored proc to bring back the possible values for the dropdown combo control
With a blank new row and sometimes even with an existing row, this value for the combo box can be NULL which is a legitimate value for it if no value selected. Problem is everything is so tightly bound if the user mistakinly clicks the dropdown then a value is populated and there's no way to get back to NULL
I've tried to catch the mousecelldown event and others to try to catch this before a value is selected but the Cancel=True doesn't work - I can catch the event but don't know how to return the cell to unclicked or reset it to NULL or pre selected value if NULL I know how to at a new row with the datatable and then set the combo datasource to it and I have my null blank value but with a tightly bound control how do I add this row?
