I want to load value from a file into a DataGridTextBoxColumn

using :

SetColumnValueAtRow(ByVal source As CurrencyManager, ByVal rowNum As Integer, ByVal value As Object)

The problem is i do not understand the CurrencyManader. How do I get it ? For the moment I overrided the Edit event:

ByVal source As System.Windows.Forms.CurrencyManager, ByVal rowNum As Integer, ByVal bounds As System.Drawing.Rectangle, ByVal readOnly As Boolean)

And I copy the correncymanager to a global var which is not a good thing. Anyone idea?

1) Why are you doing this?

2) The CurrencyManager is an underlying entity that manages navigating a DataTable that the DataGrid is bound to

1) I was doing that because i had to make something temp instead of searching was under the gun. But i know it's temp.

2) Aight, Tell me more i'm francophone or find some kind of schema, not that clear.

Loading data from a file into a DataGridTextBoxColumn so the box value is refreshed with the value found into the data file.

1) What kind of file?

2) Would binding the DataGrid to a DataTable be a possibility?

3) It sounds like what you are attempting could be done more simply, but I am not sure.

Well, it is a simple text file. I link the value of the .txt file to the datagrid and it's working fine. The DataGrid is already binded to a DataTable. But just to be sure, define binded i'm francophone

Databinding example:

    Me.DataGrid1.Datasource = table

Look here:
  Custom Object Data Binding with .NET
  http://www.15seconds.com/issue/040908.htm

If you set the DataGrid.Datasource to a datatable, then you won't need SetColumnValueAtRow, unless you are trying to do something special.

Loose translation:
Si vous placez le DataGrid.Datasource à un datatable, alors vous n'aurez pas besoin de SetColumnValueAtRow, à moins que vous essayiez de faire quelque chose de spécial. (translated)

Cannot bind to every textbox of my column.

                  dgtbMeasDataColStyle.TextBox.DataBindings.Add("Text", ATPCollection(i), "Test")

I'd like to bind every textbox.

How does that relate to SetColumnValueAtRow?  You can do both.
