Hi,
I am struggling with two way databinding in WinForms and the DataGridView.
I am binding to business object classes (rather than datatables). If I
have a collection of these business objects that is the datasource of a
DataBinding that is bound to a DataGridView (WinForms) then I was expecting
that any change to the data would be reflected in the DataGridView (in other
words I was expecting the 2 way databinding to actually...

I have multiple datagridviews on one form. I am allowing editing in the
grid, and am performing error checking.
I am validating the data, if it isn't valid, I am cancelling any other
events fired. My problem is, I am validating in grid A, if they click
in Grid B, I am popping up a message box informing them of the error,
but if they click ok on the message box, and then click in grid B
again, it goes on. The following is a code...

Hello,
I 've a Windows Form and a "DataGridView" with the "DataSource" binding with
a "BindingSource" and a "BindingNavigator", in the other hand in the same
Form, there's multiples textbox's binding with the same "BindingSource".
Well, only I want to know if there's any automatic way to change the values
of all selected rows in a datagridview, when I change the TextBox's text.
Thank you.

I've been searching forever for examples of saving data changes in a
DataGridView. There's all kinds of examples, but none really show how
to save changes. Someone please help me.
I have a Windows Forms program with a DataGridView and a BindingSource
added to a form. Here is the code I'm using to populate the grid:
Dim CRClassesTableAdapter As SqlDataAdapter
Dim CRClassesTable As New DataTable()

I'm changing from a DataGrid to a DataGridView and have run across a
problem. The items that are bound to the DataGrid have an int Property that
represents a primary key of a lookup table in my database. For example:
table JobTypes
1 | Manager
2 | Controller
3 | Supervisor
table Employee

Hi All :)
I'm converting VB6 using True DBGrid Pro 8.0 to VB2005 using DataGridView.
True DBGrid has a MultipleLines property that controls whether individual
records span multiple lines. Is there an equivalent property for the
DataGridView? I have searched, but have not found one.
I would like the user to be able to see all the columns of the table on one
screen - thus eliminating the need to use the horizontal scroll bar to view...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
