我想在
private void textBox1_TextChanged(object sender, EventArgs e){}
事件中调用
private void dataGridView1_CellMouseDoubleClick(object sender, DataGridViewCellMouseEventArgs e){}
这个事件，怎样实现啊？急！！

private void textBox1_TextChanged(object sender, EventArgs e){
dataGridView1_CellMouseDoubleClick(null,null)
}

LS是对的

也可以：dataGridView1_CellMouseDoubleClick(new object(), new DataGridViewCellMouseEventArgs())

上面两位大侠，好像两种方法都不能解决啊！能明确一点吗？谢谢

都不能解决？这不可能哦~~~

是你的dataGridView1_CellMouseDoubleClick里面没写代码吧…所以调用了没调用没区别

你设置个断点，然后单步执行，看进去没

private void txtInput_TextChanged(object sender, EventArgs e)
        {
            String strInput = txtInput.Text.ToString().Trim();
            SqlConnection myConnection = new SqlConnection

("server=localhost;database=ProductData;Trusted_Connection=yes;user id=;password=");
            SqlDataAdapter orderdet = new SqlDataAdapter("select

pId,pName,pModel,pUnit,pColor,pPurchasePrice,pMinAmount from Product where pId like '%" +

strInput + "%' or pName like '%" + strInput + "%'", myConnection);
            DataTable dt = new DataTable();
            orderdet.Fill(dt);
            dataProductBill.DataSource = dt.DefaultView;
            //dataProductBill_CellMouseDoubleClick(dataProductBill,);
        //想在这里调用dataProductBill_CellMouseDoubleClick()这个事件，但是总是报参数出错！
        }




   private void dataProductBill_CellMouseDoubleClick(object sender, DataGridViewCellMouseEventArgs e)
        {
            try
            {
                //获取DataGirdView中的值
                String strId = dataProductBill.CurrentRow.Cells["pId"].Value.ToString();
                String strName = dataProductBill.CurrentRow.Cells["pName"].Value.ToString();
                String strModel = dataProductBill.CurrentRow.Cells["pModel"].Value.ToString();
                String strUnit = dataProductBill.CurrentRow.Cells["pUnit"].Value.ToString();
                String strColor = dataProductBill.CurrentRow.Cells["pColor"].Value.ToString();
                String strPuchasePrice = dataProductBill.CurrentRow.Cells["pConsultPrice"].Value.ToString();
                String strMinAmount = dataProductBill.CurrentRow.Cells["pMinAmount"].Value.ToString();
                String strManufacturer = dataProductBill.CurrentRow.Cells["pManufacturer"].Value.ToString();
                String strRemark = dataProductBill.CurrentRow.Cells["pRemark"].Value.ToString();
                FrmProductInfo fr = new FrmProductInfo(strId, strName, strModel, strUnit, strColor, strPuchasePrice, strMinAmount, strManufacturer, strRemark);
                fr.Owner = this;               
                fr.ShowDialog();
                label3.Text = strContent.ToString ();
                label4.Text = strName;
                label5.Text = strName1;               
                fr.Dispose();
                fillData();         
            }
            catch
            {
                MessageBox.Show("没有可选商品！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Warning);
            }
        }

dataProductBill_CellMouseDoubleClick（null,null）怎么会出错哦

谢谢你的指教，可是当我加入dataProductBill_CellMouseDoubleClick（null,null）的时候，这个事件还是没有反应的，可能是参数的问题吧！
