Hello,
I would like to know if there is an event for the Datagridview control
that is trigger before the selection change and is cancelable.
I'm currently using the SelectionChanged event (using Full Row Select),
but this event is trigger only after the selection changed is completed and
therefore is non cancelable unless you keep the previous selection in a
variable and rechange the selection, which is painful.

I have some buttons that increment and decrement the index of a DataGridView.
The code below gets the updated index value. The code below highlights the
first column of the current row.
dataGridView1.CurrentCell = dataGridView1;
This is almost exactly what I want. I'd really prefer it if the code above
could highlight the entire row, rather than just the first column.
Any suggestions on how to modify the code above to highlight the...

Hi,
I have been encountering a refresh problem with DataGridView, which is bound
to a DataTable.
When I make updates (Add, Delete, update) to the DataGridView, everything
flow nicely to DataTable. No problem here.
However, when I add data (programatically) to the DataTable, the
DataGridView does not refresh right away. If I minimize and show my form,

Hi,
I have a DataGridView control, where I am setting its Datasource
property to a datatable. The DataGridView has it's MultiSelect property
set to false
I also have a handler for the SelectionChanged event.
When I load the data, I set the DataSource property, and then call
ClearSelection() to make sure there are no selected rows.

Hi, I have a problem with the datagridview not refreshed when the
application first appear on the screen.
The datagridview display data from a table in the dataset. At the same
time, I've added checkbox columns that are not bounded the table.
This datagridview is located in the tab (2nd). I thought I mention that
since that might be part of the problem (?).
When the applications start, it will need some parameter criteria selection...

Hi,
I need to tell how many rows are visible on the screen,
in my DataGridView control

Using VS2005, VB.NET,
I have a windows app with a DataGridView (lets call it DGV). At some
point in the life of my app I want to clear the selection of the
currently selected row (Multiselect=false) from DGV - to do that I
tried this:
DGV.ClearSelection()
Cosmetically this appears to work but it appears that the DGV still
stores the index value of the selected row. If the 1st row I click on
after executing ClearSelection() is the row...

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:
