C#中datagridview单元格跳转问题
我现在在keydown事件是写了代码，跳转到当前行的某个单元格，但是运行之后，跳转的是下一行的某个单元格，不知道是为什么？
程序代码： if (this.dgvyzlr.Rows[rowid].Cells["ischild"].Value.Equals("1"))
{
//如果是子医嘱，则跳过用法，频率，直接跳到实际用量
this.dgvyzlr.CurrentCell = this.dgvyzlr.Rows[rowid].Cells["shijiyongliang"];
this.dgvyzlr.Rows[rowid].Cells["yongfa"].ReadOnly = true;
this.dgvyzlr.Rows[rowid].Cells["pinlv"].ReadOnly = true;
}
else
{
if (this.cblrfs.Text.Equals("自由录入"))
{
//规格获得焦点
this.dgvyzlr.CurrentCell = this.dgvyzlr.Rows[rowid].Cells["guige"];
this.dgvyzlr.Rows[rowid].Cells["guige"].ReadOnly = false;
}
else if (this.cblrfs.Text.Equals("临床项目"))
{
//用法获得焦点
this.dgvyzlr.CurrentCell = this.dgvyzlr.Rows[rowid].Cells["yongfa"];
this.dgvyzlr.Rows[rowid].Cells["yongfa"].ReadOnly = false;
}
}
this.dgvyzlr.Rows[rowid].Cells["yizhuneirong"].Value = this.dgvypxm.Rows[index].Cells["ypmingcheng"].Value.ToString();//医嘱内容
this.price = double.Parse(this.dgvypxm.Rows[index].Cells["ypdanjia"].Value.ToString());//单价
this.dgvyzlr.Rows[rowid].Cells["yizhuneirong"].Tag = this.dgvypxm.Rows[index].Cells["ypdanjia"].Value.ToString();
this.dgvyzlr.Rows[rowid].Cells["guige"].Value = this.dgvypxm.Rows[index].Cells["ypguige"].Value.ToString();//规格
this.dgvyzlr.Rows[rowid].Cells["yongliangdw"].Value = this.dgvypxm.Rows[index].Cells["ypyongliangdw"].Value.ToString();//用量单位
this.dgvyzlr.Rows[rowid].Cells["danwei"].Value = this.dgvypxm.Rows[index].Cells["ypdanwei"].Value.ToString();//单位
this.dgvyzlr.Rows[rowid].Cells["yaopinfenlei"].Value = this.dgvypxm.Rows[index].Cells["ypsx"].Value.ToString();//药品分类
this.dgvyzlr.Rows[rowid].Cells["ypbh"].Value = this.dgvypxm.Rows[index].Cells["ypbm"].Value.ToString();//药品编号
this.dgvyzlr.Rows[rowid].Cells["ydbh"].Value = this.dgvypxm.Rows[index].Cells["ypyaodian"].Value.ToString();//药典编号
jlxs = float.Parse(this.dgvypxm.Rows[index].Cells["jl_xs"].Value.ToString());//剂量
this.dgvyzlr.Rows[rowid].Cells["lcxmbh"].Value = "000000";
#region 药房编号
string yfbh = czyfbh(this.dgvypxm.Rows[0].Cells["ypyaofangmc"].Value.ToString());
this.dgvyzlr.Rows[rowid].Cells["yfbh"].Value = yfbh;
#endregion

this.dgvyzlr.BeginEdit(true);
this.pnypxm.Visible = false;private void dgvyzlr_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{

// 取得被表示的控件

在dgvyzlr的PreviewKeyDown的事件中调用这个方法的话，执行到this.dgvyzlr.BeginEdit(true)这句，程序就会跳转到EditingControlShowing和ProcessCmdKey里边，然后窗体上就会跳转到下一行，如果不执行这一句，或者是在dgvypxm的keydown事件中执行第一个方法，就没问题，不知道是哪里出了错？？请各位帮帮忙
