So, what are the current plans for the DataGridView virtual mode. 
Any chances we will see it on Mono 2.0 final release?

Thanks in advance.

No, it will not be in Mono 2.0.  Perhaps it will be in 2.1 or 2.2.

[Mono-dev] DataGridView virtual mode, exception

2008-04-04 Thread Cetin Sert 
Dear Mono Devs,

mono DGVV.exe

Unhandled Exception: System.NullReferenceException: Object reference not set
to an instance of an object
  at System.Windows.Forms.DataGridView.set_RowCount (Int32 value) [0x0]
  at (wrapper remoting-invoke-with-check)
System.Windows.Forms.DataGridView:set_RowCount (int)
  at DGVV.Form1..ctor () [0x0]
  at (wrapper remoting-invoke-with-check) DGVV.Form1:.ctor ()
  at DGVV.Program.Main () [0x0]

when setting RowCount property on a DataGridView instance in virtual mode, I
get the above exception with Mono 1.2.4, 1.2.6 and 1.9.

Is virtual mode of DataGridView usable in Mono (1.9)?

If it is, what am I doing wrong?
If it is not, what other winforms grid control do you suggest me to use? (It
should have a virtual mode support... I tested SourceGrid but it does not
draw properly when in virtual mode.)

Best Regards,
Cetin Sert

I do not know of any alternatives either.  Perhaps someone else does.
