由于DataGridView的单元格DataGridCell处于编辑的时候,
当你按Enter键,那么DataGridView是不会激发KewPress/KeyDown/KeyUp这些事件的,
因为这个时候的DataGridView是一个容器。
我们无法直接在DataGridView的KeyPress事件中做处理,原因上面已经说明,也无法使用CellEndEdit这个事件,
因为这个事件不一定是通过Enter来触发的,直接鼠标移动到其他单元格也会的,因此我们需要修改一下:
1、项目里,添加组件MoMoDataGridView
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Diagnostics;
using System.Text;
using System.Windows.Forms;
namespace UFIDA.U8.Portal.Interface
{
public partial class MoDataGridView : DataGridView
{
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if (keyData == Keys.F2)
{
this.OnKeyPress(new KeyPressEventArgs('f'));
return true;
}
else if (keyData == Keys.Enter)
{
this.OnKeyPress(new KeyPressEventArgs('e'));
return true;
}
else if (keyData == Keys.Delete)
{
this.OnKeyPress(new KeyPressEventArgs('d'));
return true;
}
else
return base.ProcessCmdKey(ref msg, keyData);
}
}
}
2、然后将这个控件拖到窗体中 添加KeyPress事件
private void dgData_KeyPress(object sender, KeyPressEventArgs e)
{
dgData.EndEdit();
int irows = dgData.CurrentCell.RowIndex;
int icols = dgData.CurrentCell.ColumnIndex;
if (irows > -1 && icols > -1)
{
if (e.KeyChar == 'd')
{
if (dgData.CurrentCell.ReadOnly == false)
dgData.CurrentCell.Value = null;
}
if (e.KeyChar == 'f')
{
if (dgData.CurrentCell.ColumnIndex == 1)
{
string cinv = "";
if (dgData.CurrentCell.Value != null)
{
if (dgData.CurrentCell.Value.ToString() != "")
cinv = dgData.CurrentCell.Value.ToString();
}
frmInfor infor = new frmInfor("存货", cinv);
infor.ShowDialog();
dgData.CurrentCell.Value = frmInfor.rc;
}
}
}
}
