I dont exactly know the reason ... but you can do something like this
to take desired effects in your button click handler.
private void button1_Click(object sender, EventArgs e)
{
//for combobox on 2nd tab.. this combobox is on second tab
tabControl1.SelectedIndex = 1;
comboBox1.Text = "test1";
//for combobox on 1st tab.. this combobox is on first tab
tabControl1.SelectedIndex = 0;
comboBox2.Text = "test2";
}
