[dba-VB] WinForms: What is the best event for custom drawing on a leftmost cell of DataGridView

Hi Shamil

I guess you have googled what you need to at this moment ...

The one strange thing about the row selectors is the default large width. Too wide in my opinion.

Hi Gustav --

Thank you. Yes, that should help. I must note I didn't google for that
somehow - just for RowPostPaint event.
It looks simple now - just information how to draw on left-top cell is
missing.

You're so quick with googling could you find that information? :) (If you'll
not find it quickly in your free time - forget it... )

<<<
Or could you do that and then use column 0 to simulate the row headers?
>>>
I wanted to use row headers - yes, simulation seems to be an "easy way to
go" - but I'd prefer row headers, which have special display view and
properties, which I do not want to spend time on simulation
implementation...

Thank you.

Hi Shamil

I see. If you didn't need to draw your +/- you could just remove the row
headers. Or could you do that and then use column 0 to simulate the row
headers?

This:

gs.org/web-forms/121172/+%22C%23%22+DataGridView+show+rowselector+arrow&cd=7
&hl=da&ct=clnk&gl=dk

located in the Google cache suggests:

Handle the RowPostPaint event (Code Snippet):

void dataGridView1_RowPostPaint(object sender,
DataGridViewRowPostPaintEventArgs e) {
  e.PaintHeader(DataGridViewPaintParts.All &
~DataGridViewPaintParts.ContentBackground);
}

Also, I located this thread which, however, perhaps collides with your +/-
drawing:

You may have seen it before (I just googled) but the topic seems pretty
close to that of yours.
