centering a childform in MDI parent

[Peted]

I have a simple c# app that opens a child form in a mdi parent.

I want the child form to open in the center of the mdi parent, so i
can open the child form ok, it all works fine, but setting

frmConfig = new ConfigForm(this );
frmConfig.MdiPa rent = this;
frmConfig.TopLe vel = false;

frmConfig.Start Position = FormStartPositi on.CenterParent ;
frmConfig.Show( );
does not seem to work regardless if i set it runtime or in the windows
properties at design time.

The only way i can get CenterParent to work is to display the form
using Showdialog(), but then it has to be top level and the user can
drag it out the bounds of the MDI parent.
What i have found is if i use

frmConfig.Start Position = FormStartPositi on.CenterScreen ;
this will display the childform in the center of the parent, seemingly
regardless of where the parent is located on screen.
All the internet examples ive found say to use
FormStartPositi on.CenterParent ;

Does anyone have any idea whats going on and how it should be done ?

dear all,
how to know some fields were modified by user?
list bellow my project:
components: DataGridView,Da taSet
when user change the DataGridView colmons field value,we can use
Dataset.Getchan ges.tables[0] to list current record was modified.
but I can't know which fields were edited,only know the user edit the row.
even though I can't know it if a new record or edited record.

Hi,
I also have faced same problem long back...
I am just giving you hint ... not a solution

Put frmConfig.Start Position = FormStartPositi on.CenterParent ;
statement immidetely after frmConfig = new ConfigForm(this );

and put CenterParent in design time also.
