DataGridView

Saludos a todos los del grupo,

Estoy realizado una pequeña aplicación en la cual a un DataGridView
le paso como datasource una lista generica de una clase Alumno. Asi:

List<Alumnolist a = new List<Alumno>();
Alumno alumno1 = new Alumno();
alumno1.nombre = "AAA";
alumno1.apellid o = "BBB";
lista.add(alumn o1);

datagrid.dataso urce = lista;

Cuando se muestra el formulario aparece el registro que agrege en la
lista, pero al datagridview lo configuré para que permita agregar,
eliminar y actualizar pero al momento de mostrar la pantalla no muestra
el registro ultimo en el grid para que pueda agregar uno nuevo, puedo
eliminar y puedo actualizar, pero no agregar nuevos.

Como puedo tener esta funcionalidad automaticamente ?, ¿Cuando agrege,
borre o modifique en el DatagridView tambien se modificará la lista?

Saludos,
Mariano

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. But when I click on a cell of that row, I suddenly got this error: "Index -1

Hello, I am populating a datagridview from a datatable and filtering the number of rows with a dataview object. Is there a way to retrieve the rows displayed by the datagridview into a separate datatable without having to loop through each column in the datagridview? Or is there a way to retrieve the rows from the original datatable filtered by the dataview into a separate table? I only want to copy the rows from the main table that...

Can anyone tell me the best way to update a dataset while it is being edited/viewed in the DataGridView control? Is this something that should be inserted into one of the grid's events? or should you update after closing the grid/form, etc.? Also, can you tell me the best book to buy that fully explains the DataGridView control? Thanks.

Is there an equivalent of the DataGrid's DataGridTableStyle for the DataGridView? If not, is there an easy way to duplicate the DataGridTableStyle's functionality for the DataGridView? Here's the background for my question... Before I switched my application over to the Fx 2.0, I used a DataGrid to display my data. I would store different DataGridTableStyles (each one with a custom set of columns) in the DataGrid.TableStyles property...

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...

I have DataGridView in virtual mode containing 3500 rows. In code below, assigning to RowCount value to 3500 takes 8 seconds. CPU usage goes high at this time. Stepping by F11 into user code shows few celltemplate property getters and combobox/datecombo constructor calls without database access which does not take a lot of time.

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...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
