Hi Ben,
Well, the name of the column isn't "Id". You've named it,
"idDataGridViewTextBoxColumn".
The indexer of the row.Cells collection requires the row's Name, not the value
of the HeaderText property.
this.selectedRowIndex = (int) row.Cells["idDataGridViewTextBoxColumn"].Value;
BTW, you probably shouldn't use try..catch here. It doesn't really make sense
here; especially since you're not catching any specific exception.

many thanks for your quick answer
but it s what I did :
//
// idDataGridViewTextBoxColumn
//
this.idDataGridViewTextBoxColumn.DataPropertyName = "Id";
this.idDataGridViewTextBoxColumn.HeaderText = "Id";
this.idDataGridViewTextBoxColumn.Name =
"idDataGridViewTextBoxColumn";
this.idDataGridViewTextBoxColumn.Visible = false;
and It still does not work :(
I wrote a very small project to reproduce this problem, I could send it
to you if you want ?
I ll take all advice or ideas :))

Hi Ben,
IIRC, your code should work if you really did hide the column.
By removing the column from the list in the designer you're not hiding the
column - you're completely removing it from the collection.
You must set Visible = false instead.

hi all
I m using the visual studio designer to create 1 Dataset with 1 table
with 3 columns : Id, Name, Birthday.
Once this done, still with the designer, I m creating a datagridview
and choose my dataset as DataSource.
magic : the columns appear in the datagridview.
Still with the designer, I can change the properties of the fist column
"Id" to hide it.
now it s time to write some code :
on the cellClick event I want to get the value of the Id, unfortunaly
it throws an exception cause the column is hided
DataGridViewRow row =
(DataGridViewRow)dataGridView.Rows[e.RowIndex];
if (row != null)
{
try
{
this.selectedRowIndex =
(int)row.Cells["Id"].Value;
}
catch
{
int a = 1;
}
}
Does anyone know how to get the value of a hiding column when the user
clics on a row ?
thx for your help
