C# dataGridView\u CellContentClick:无法对控件调用Invoke或BeginInvoke

有人能告诉我我做错了什么吗这段代码，它产生了味精

“在创建窗口句柄之前，无法对控件调用Invoke或BeginInvoke。”

private void dataGridView_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {

                if (e.ColumnIndex == buyColumn.Index)
                {

                    double openprice = (double)dataGridView.Rows[e.RowIndex].Cells[offerColumn.Index].Value;
                    string symbol = dataGridView.Rows[e.RowIndex].Cells[symbolColumn.Index].Value.ToString();
                    double quanity= (double)dataGridView.Rows[e.RowIndex].Cells[quanityColumn.Index].Value;

                    MessageBox.Show("I buy " + symbol +  " with "  + quanity + " at " + openprice);
            }        

更新：调试后，这3行导致问题，请告诉我如何修复

double openprice = (double)dataGridView.Rows[e.RowIndex].Cells[offerColumn.Index].Value;
                        string symbol = dataGridView.Rows[e.RowIndex].Cells[symbolColumn.Index].Value.ToString();
                        double quanity= (double)dataGridView.Rows[e.RowIndex].Cells[quanityColumn.Index].Value;

试一试

不可用，没有开始/调用的迹象，决不应在单击事件上发生。发布异常的堆栈跟踪。

        if (dataGridView.IsHandleCreated && e.ColumnIndex == buyColumn.Index)
        {

            double openprice = (double)dataGridView.Rows[e.RowIndex].Cells[offerColumn.Index].Value;
            string symbol = dataGridView.Rows[e.RowIndex].Cells[symbolColumn.Index].Value.ToString();
            double quanity= (double)dataGridView.Rows[e.RowIndex].Cells[quanityColumn.Index].Value;

            MessageBox.Show("I buy " + symbol +  " with "  + quanity + " at " + openprice);
         }
