博客给出了一段代码，包含Grid_MouseMove和ShowHitInfo两个方法。Grid_MouseMove方法在鼠标移动时调用ShowHitInfo方法。ShowHitInfo方法根据鼠标点击的列名，从Grid中获取对应单元格的显示文本，并赋值给相应的文本框或下拉框，若列名不匹配则赋值为Null。

  private void Grid_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
  {
  ShowHitInfo(this.gridView1.CalcHitInfo(new Point(e.X, e.Y)));
  }

  private void ShowHitInfo(DevExpress.XtraGrid.Views.Grid.ViewInfo.GridHitInfo hi)
  {
   DevExpress.XtraGrid.Views.Base.ColumnView cgv =
    (DevExpress.XtraGrid.Views.Base.ColumnView)Grid.MainView;

   string columnName = hi.Column == null ? "No column" : hi.Column.Caption;
   switch(columnName)
   {
       case "账号":
     txtUserName.Text = cgv.GetRowCellDisplayText(hi.RowHandle,hi.Column);
     break;
    case "密码":
     txtPassword.Text = cgv.GetRowCellDisplayText(hi.RowHandle,hi.Column);
     break;
    case "真实姓名":
     txtRealName.Text = cgv.GetRowCellDisplayText(hi.RowHandle,hi.Column);
     break;
    case "电子邮件":
     txtEmail.Text = cgv.GetRowCellDisplayText(hi.RowHandle,hi.Column);
     break;
    case "角色":
     cbRole.Text = cgv.GetRowCellDisplayText(hi.RowHandle,hi.Column);
     break;
    default:
     txtUserName.Text = "Null";
     txtPassword.Text = "Null";
     txtRealName.Text = "Null";
     txtEmail.Text = "Null";
     cbRole.Text = "Null";
     break;
   }
