Child form disactivation on new data to datagrid! (Mainform jumps to TOP)

Hi,


I have notices forms activating/disactivating problems.
PLEASE HELP ME, it's very strange!

Try this:
1)Create MainForm+Datagrid(+new dataset assign to
datagrid)
2)Create Timer on MainForm + on timerTick add new data to
dataset (see below)
3)Create another form (child)
4)Execute all

ABNORMAL Behaviour:
Child form always jumps to background on TIMER TICK!!!
(MainForm jumps to TOP)

SW details:.NET framework 1.1.4322, C#,VStudio 2003

Source:

private void timer_Tick(object sender, System.EventArgs e)
{
DataRow row = dataset.Tables["Table"].NewRow();
row["Col1"] = "This is bug";
row["Col2"] = "child window deactivates!";

// this causes the deactivation of any child windows!
// BUT WHY!!! I do not wanna activate MainForm!!!!
dataset.Tables["Table"].Rows.Add(row);
}


best regards
Daniel Koci



+Other my-known Dataset Bugs:

1) See my record from 19.8.2003 (FRMWRK 1.1 - dataview
receives just ListChangedType.Reset instead of
ListChangedType.ItemChanged !!! (works fine in 1.0))

2) TabPage problems (Horizontal scrollbar on DataGrid
will not updates on TabPage when Page changed)
