How to keep focus on FarPoint.Win.Spread.FormulaTextBox

Hi guys, I'm trying to use FormulaTextBox to allow the user enter their custom formula, is there a way that we can keep the focus on the FormulaTextBox after the user enter an invlid formula and press enter key?

可通过formulaTextBox1_Leave事件判断：

private void formulaTextBox1_Leave(object sender, EventArgs e)
{
string txt = fpSpread1.ActiveSheet.ActiveCell.Text;
if (txt == "#NAME?" || txt == "#DIV/0!" || txt == "#REF!")
{
formulaTextBox1.Focus();
}
return;
}
