Hi, I'm using the DataGridView in VB.NET 2.0. The DataSource is a Generic List of a custom class0: lstMyPersonnes = New List(Of clsPersonne). When I add a new clsPersonne to lstMyPersonnes, and rebind the lstMyPersonnes to my DataGridView.dataSource, it shows the new record in the DataGridView as it should be.

Problem in datagridview datetimepicker column.

by: priyamtheone | last post by:

I'm trying to make a datagridview column to act like a datetimepicker column (C#.Net 2005). These are the behaviours that the dgv should have: 1) Initially all the cells of the dtp column should be blank unless they are filled by the user. 2) As soon as the user enters a cell, the dtp control should appear as the editing control of that cell. If there's a value in the cell beforehand, that value is set as the value of the dtp editing control...

The easy way to turn off automatic updates for Windows 10/11

by: Hystou | last post by:

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.
