Is there a way to discover the starting X & Y position (in Pixels) of a
Cell within a DataGridView control on a Windows Form? (VS2005)
I've searched everywhere, and tried everything I can think of, but can't
seem to find the answer.
Thanks for any help.

The situation:
* I have a ButtonColumn in a DataGridView.
* When the user preses one of the buttons, a dialog appears.
* Based on what the user selects in the dialog, data is entered
programmatically into the the underlying cell (i.e., I'm setting Value
property of the cell based on user input, but the user is not directly
entering any data).
The problem:

I have combobox column in DataGridView.
Up and down error keys should be used to navigate previous and next row in
grid.
For this I override them in ProcessCmdKey() event.
When combobox dropdown menu is open arrow arrow keys should move to previous
and next item in
dropdown menu instead of moving betveen rows.
How to check that combobox dropdown menu is open in ProcessCmdKey() ?

Hello.
I have a DataGridView with a lot of rows.
I created a sort of "Goto" .
I used the CurrentCell property.
The DataGridView scrolls down
and the new cell is now visible
and it is blue selected.
But it is always displayed at the bottom (= the last row)

Hi all,
I want be able to enable and disable navigation buttons when on the first or
last row of a DataGridView object.
I have a populated DataGridView and two buttons - "First Row" and "Previous Row".
If the user clicks "First Row", they are taken to the first row in the DataGridView via:
Private Sub btnFirstRecord_Click(...)
' Move to first record in job list

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...

Someone has an example, C#, about how to set the cell(int row, int col) as
the current cell for a DataGridView. The example, in the help file, about
DataGrid.CurrentCell Property (Set)
myGrid.CurrentCell = new DataGridCell(1,1);
does not work, fro a DataGridView, since we cannot create a DataGridView
Cell while specifying only its row and column.

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
